O12S (Omega)
Note
This guide is written assuming you have all Blue Mage spells, appropriate gear, and know how to play your chosen role.
The switch taunts you. You cannot resist. A satisfying “click” and your moment of weakness has activated a new phase of the Savage Initiative. This time, however, something is different. The broadcast is interrupted by an unexpected transmission─a message from beyond oblivion. A familiar voice guides you in an unfamiliar tone, and arms you with knowledge of impossible simulations. Your evolution is at hand.

Party Setup
For this fight I recommend having two tank mimics, two healer mimics, and four DPS mimics in the first phase. In the second phase, the off-tank can switch to DPS and if you have a confident healer you can switch one of the healers to a DPS mimic, but I don’t recommend it personally.
Phase 1: Omega M+F
The first phase has two targets that need to be tanked, and for this reason this is the only fight (currently) where I recommend having two tank mimics. The auto-attacks hurt, and the extra defensive stats from tank mimicry really help with this. Mechanically the first fight isn’t too difficult, but single mistakes can easily cause cascading failures that lead to a wipe. The large Omega eye that appears on the edge of the arena will be considered “north” for every mechanic. Players should have assigned clock positions for some mechanics and be ready to adjust to Celestriad positions just like in O8S. Additionally, the party should be split into two light parties with one tank, one healer, and two DPS.

Beyond Defense/Pile Pitch
When the boss is pulled, the tank should pull Omega-M to the far east side of the arena. The eye will cast Suppression which is a line AOE attack making the center unsafe, so we’ll handle the first bit of the fight on the east side. The fight opens up with Omega-M casting Beyond Defense which targets a random player with a small AOE that applies a magic vulnerability, followed by Pile Pitch which targets a different random player and splits damage among everyone hit (stack mechanic).
To handle this mechanic, assign four pairs of players to be on the boss’s north,
south, east, and west. Beyond Defense will hit one pair of players, and
afterwards everyone else should stack behind the boss. If the pair behind the
boss got hit they will need to move elsewhere. If this was done correctly, then
all of the DPS should be in
Revenge Blast range and can start
blasting. Due to damage variance it’s possible that someone is not in range, and
the off-tank will only be in range if they did not eat food. For this reason, I
actually recommend that the off-tank does not eat food in Phase 1. Additionally,
due to random targeting there is a 1/7 chance that someone in the initial pair
hit by Beyond Defense also gets hit by Pile Pitch and dies. If this happens,
just jump off and start over. It’s only the first mechanic and nothing is really
lost by resetting, but by doing the opening this way you can gain a ton of
damage from
Revenge Blast.
After awhile, Omega-M will melt into a puddle and arise as Omega-F. Omega then
uses Discharger which deals mild AOE damage but has a huge knockback, so
position on her rear to prevent getting knocked off the arena. Before the damage
goes out, it is helpful to have the main tank use
White Wind to
heal up the party. This is also a really good opportunity to use
Cold Fog.
Superliminal Motion
After the knockback, the tank should pull the boss to the center and face her
towards the eye. Omega-F will cast Superliminal Motion while the eye uses
Advanced Suppression. Superliminal Motion is a 270 degree cleave in front of
the boss, while Advanced Suppression is a circle AOE centered on the eye; this
means that the safe spot is in the south side behind Omega-F. After these casts
go off, the party needs to spread into their clock positions for Optimized
Fire III which is just a moderate damage AOE on every player. If there is
zero mitigation on this cast, then the party will be in
Revenge Blast range again, but it’s a very short window.
Electric Slide
Once Omega-F melts down into a puddle, heal up and apply
Gobskin.
Separate into your assigned light parties into the south and west, and two stack
markers will go out on random people. If two stack markers are on the same side,
have one stack marker swap with someone from the other side. A simple priority
system or small “conga line” works well for this, or you can just call it out on
the fly.
After the stack damage hits, return to the center and heal up. Once you see
Omega-M and Omega-F return to their humanoid form, use
Surecast
to avoid the knockback from Omega-F. Once this damage goes out, return to your
light party spots (if any swaps occurred, just return to your original spots).
Firewall/Resonance
Omega-M and Omega-F will both cast Firewall, which will make them immune to all damage except from the four closest players when the cast finishes. Make sure your light party is closer to your target than the other target so that everything resolves and assigns correctly. After a short delay they will both cast Resonance and receive either Local or Remote Resonance buffs. If it’s Local, they will need to be pulled apart by having light party 2 move to the east (while light party 1 stays in the west). If it’s remote, then they will need to be pulled together so light party 2 will move to light party 1 on the west. Tanks should try to position the bosses so that they’re not directly on the wall for the next mechanic, as players will need to have room to stand between the bosses and the edge of the arena.
Fundamental Synergy
Omega-M and Omega-F will begin casting Fundamental Synergy, which is usually just called “numbers” or “limit cut.” This is one of the trickiest mechanics in the phase, but it’s pretty straightforward once you know how to handle it. M and F will mark their light parties with numbers 1-4 and then start charging between the targets in ascending order. The Electric Slide charge does proximity based damage and has a very wide line AOE. The actual AOE is “short” and stops exactly at its target, so anyone standing directly behind will not get hit. One of the easiest strats for handling this is the “box strat”:
- Once numbers go out, all odd numbers should go to the opposite side from where they started. Local/Remote Resonance does not matter here – odd numbers just need to go to whichever side their targes is not on. Even numbers stay where they are.
- Have one set of numbers orient to the east/west marker, and one set of numbers be slightly south of that. I like having “squares” be on the marker and “triangles” be south of the marker, but many groups find it easier to do it based on light party, e.g. light party 1 is on markers and light party 2 is just south of markers.
- Once you’re at your starting position, have the lower number within your pair (1 on the odd side, 2 on the even side) take a step off the wall and the other person stand just behind them. This should result in the 1’s standing right in front of the 3’s and the 2’s standing right in front of the 4’s.
- The bosses will become untargetable and start charging across the room. When you or your partner gets hit, swap places with them.
- After all four charges have happened, return to your targets.
While the execution is simple, if anyone makes a mistake it’s very likely to result in a wipe. The tanks will be taking a ton of damage from auto-attacks at the beginning and end of the mechanic so make sure to watch them closely.
After the chargers finish, the bosses will use Laser Shower, a moderate
raidwide, which is a good opportunity to use
Cold Fog. This hits
pretty hard, so
Addle and
Magic Hammer can be
helpful here. They will both follow up with Solar Ray, an extremely
hard-hitting tankbuster with a small AOE. This is survivable with
Dragon Force and
Chelonian Gate, but I recommend just using
Diamondback.
The tanks should then move both targets to the center and face them north for
the next mechanic, which will either be Synthetic Shield or Synthetic
Blades. Each mechanic is described below, but the order in which they occur is
random. At this point I recommend holding on to
J Kick for
mobility >}}.
Synthetic Shield
Synthetic Shield is the more difficult of the two mechanics. This is functionally a combination of Beyond Defense, Optimized Blizzard III (cross-shaped AOE around Omega-F), Pile Pitch, Optimized Fire III, Beyond Strength (donut AOE around Omega-M), and Efficient Bladework (point-blank AOE centered on Omega-M). The way we handle this is:
- Point bosses north until first AOE markers appear.
- Move into Celestriad positions (as in O8S) and spread from your partner.
Use
Sprint as the next bits happen quickly.
- If you did not get hit by Beyond Defense, stack in the center to soak Pile
Pitch. This is a great time for a healer to use
Angel's Snack and a tank to use
White Wind (but be cautious of threat).
- Spread out to clock positions for Optimized Fire III. This can be a good
opportunity to use
Cold Fog, but the timing is a little bit difficult with all of the movement.
- Omega-M will jump to a random person and use Beyond Strength. Once he does
so, use
J Kick to dodge the AOE.
- Move away from Omega-M to avoid Efficient Bladework.
- Heal up and mitigate the following Laser Shower.
Synthetic Blades
Synthetic Blades is a little bit easier. This is functionally a combination of Superliminal Steel (cleaves on the left and right of Omega-F), Optimized Blizzard III, Pile Pitch, Superliminal Motion, Optimized Fire III, and Efficient Bladework. The way we handle this is:
- Point bosses north until Superliminal Steel cast begins.
- Stack behind the bosses (south of the center of the arena).
- After the steel cast finishes, step directly to the east to avoid Optimized
Blizzard III and share Pile Pitch. This is a good opportunity to use
Cold Fog.
- Return to the starting point south of center.
- Spread out to clock positions for Optimized Fire III while avoiding the Efficient Bladework AOE.
- Heal u pand mitigate the following Laser Shower.
After the previous mechanic finishes, Omega-M and Omega-F will cast Firewall and
Resonance again. This will require a tank swap as it swaps the Firewall debuffs
on everyone. This is easily accomplished by just stacking them together and
casting
Frog Legs after the cast finishes. They will then receive
whichever Resonance debuff they didn’t receive before, followed by Fundamental
Synergy which is handled the same way as before.
After Fundamental Synergy is done, bring the bosses back to the center and face them north again. Whichever of Synthetic Shield or Synthetic Blades didn’t happen before will happen now, so handle it as described above.
Limit Break
The final set of mechanics to deal with is Limit Break, where they will
quite literally use several Limit Break attacks in sequence. Someone will be
targeted with Sagittarius Arrow (a line AOE), someone with Meteor (a
proximity-based raidwide centered on the target), both tanks with Blade
Dance (a heavy-hitting tankbuster), followed by Suppression from the eye and
finally Cosmo Memory (a massive raidwide hit). This is a lot of incoming
damage and tough to resolve with mostly random targeting, so instead we will
just not handle it. Everyone should move to one side of the arena together
(either east or west) and use
Mighty Guard. As soon as the markers
go out, everyone should use
Diamondback. Everyone should survive
all of the damage, but keep
Mighty Guard up until after Cosmo
Memory since it hits extremely hard. After Cosmo Memory the tanks will need to
Diamondback again for Blade Dance.
The Limit Break sequence will repeat one more time, but the eye will use Advanced Suppression instead of Suppression. This doesn’t materially change how we handle the mechanic, so we can just handle it exactly the same way (just don’t be too close to the eye).
Final Sting
Omega-M and Omega-F’s Final Sting threshold is about 4% each. Once they are at
7%, apply
Off-guard, use
Moon Flute, any Primal
abilities you have, then finish with
Whistle and
Final Sting. Be very careful to only Sting the target to which you are
attuned via Firewall. Once one of the targets is “dead” (meaning it hits .1% HP
and Firewall debuffs are removed), that target’s players can switch to the
remaining target to finish it off.
Phase 2: Final Omega
This phase has some quite challenging mechanics and is one of the harder Blue
Mage fights in general. When we first received the level 70 update there was a
bug causing our DOT effects to be unable to Crit/Direct Hit, so the DPS check
was extremely tight and required the use of
Revenge Blast. Since
the bug was fixed and openers have been optimized from week one, the DPS check is
nowhere near as tight and the use of
Revenge Blast is no longer
recommended.
Utility Spells
-
Diamondback
-
White Wind
-
Frog Legs,
Avail, and
Blood Drain for off-tank.
Target Analysis/Savage Wave Cannon
The fights opens up immediately with the Target Analysis/Savage Wave
Cannon tankbuster combo. Omega will pick randomly from the two targets with
top enmity and hit them with Target Analysis, which deals mild AOE damage and
applies a magic vulnerability debuff. He then follows up with Savage Wave
Cannon, a line AOE that deals significantly more damage to whoever is closest to
the boss. The off-tank should use
Frog Legs somewhere in their
Moon Flute opener and if they are targeted by Target Analysis use
Avail on the main tank. The main tank will just use
Diamondback no matter what and take the damage. It’s also a good idea for
the main tank to use
White Wind early on in the pull to generate a
large amount of threat to ensure that the off-tank is above the rest of the
party after using Frog Legs. For positioning, the main tank can be
north of the boss, the party south of the boss, and the off-tank to the side of
the main tank to still be in Avail range.
Patch
After the tankbuster combo, Omega will use Patch. In my opinion this mechanic requires the tighest execution in the whole fight. Fortunately, it’s right at the beginning so you will get tons of practice. Unfortunately, it happens three times in the fight so you need to be consistent at it.
Omega will apply two pairs of red/green and two pairs of blue tethers between random targets, with each player receiving exactly one tether. The red/green tethers detonate when their targets are too close, while the blue tethers detonate when their targets are too far. The tethers will also detonate when they time out. When detonating, they deal moderate raidwide damage and apply magic vulnerability debuffs. If two pop at once it will kill everyone. Essentially what we need to do is pop the tethers in a controlled manner while also dealing with Diffuse Wave Cannon and Oversampled Wave Cannon. Diffuse Wave Cannon is a set of either front/rear or flank cleaves, and Oversampled Wave Cannon is a massive tankbuster with a pretty large AOE that targets two random players on whichever side the “monitors” appear. Diffuse Wave Cannon’s safe spot is indicated by whichever side has the glowing orbs, and Oversampled Wave Cannon will always be on either the boss’s left or right.
There are two approaches for handling the tethers: GGBB (green, green, blue, blue) or GBGB (green, blue, green, blue). Regardless of which order your group uses, you will need to set up a priority system with five different people to know who resolves the first tethers. I recommend using the main tank and off-tank as first and second priority, and the remaining three can be whoever has the lowest ping/fastest reflexes/most confidence in adjusting. Ping isn’t actually a huge issue, as a group I was in had someone on the other side of the planet with 300 ping as our first priority (after tanks) and executed it extremely consistently.
The first method for popping tethers is GGBB. By doing it this way, we can
guarantee that the MT/OT are the players taking the monitor tankbuster every
time. The trade-off is that people need to be more cautious with their blue
tethers and stay relatively close to the boss to make sure they don’t
accidentally pop tethers early. Additionally, the MT will need to mitigate the
tankbuster using
Dragon Force and
Chelonian Gate
instead of
Diamondback. These trade-offs are generally worth it
for simplicity. Here is a
toolbox for
that method, and the steps to follow are:
- The five priority players stand inside the boss’s hitbox and everyone else stands at the rear.
- Once debuffs go out, the player with the highest priority that has one of the green/red tethers moves to the front of the boss while everybody else moves to the rear. This will cause one of the close tether pairs at the rear of the boss to detonate immediately.
- When Diffuse Wave Cannon begins casting, rotate clockwise to avoid damage if needed.
- If Diffuse Wave Cannon required the party to rotate, then rotate back immediately to make the following monitor movement easier. The remaining close tether pair should step in to the boss’s hitbox to detonate their tether.
- Once the monitors appear, the MT and OT should move to the side with the
monitors, while the party moves to the side without the monitors. It is
extremely important that you do not go beyond the boss’s hitbox as popping
blue tethers early will kill the tanks. The OT can mitigate with
Diamondback and the MT can mitigate with
Dragon Force and
Chelonian Gate. The MT will survive getting hit by both busters if they overlap as long as they get healed quickly, but it’s generally a better idea to avoid overlap if possible. While the monitor buster is happening, determine the next blue tether that needs to break (you can defer to priority for this or just call it out on the fly).
- After the tankbuster hits, break the blue tether.
- Once the magic vulnerability debuff falls off, break the remaining blue
tether. The last blue tether could be between the tanks, and this is why we
want our MT to not use
Diamondback.
The second order for popping tethers is GBGB. Using this method we don’t need to
be as careful about early pops/distance, but it does mean that any two of the
five priority players need to be ready to take the monitor tankbuster with
Diamondback. This is what my group did in week one, but I don’t think
it’s quite as consistent as the other method. Here is a
toolbox for
that method, and the steps are outlined below:
- The five priority players stand inside the boss’s hitbox and everyone else stands at the rear.
- Once debuffs go out, the player with the highest priority that has one of the green/red tethers moves to the front of the boss while everybody else moves to the rear. This will cause one of the close tether pairs at the rear of the boss to detonate immediately.
- When Diffuse Wave Cannon begins casting, rotate clockwise to avoid damage if needed.
- If Diffuse Wave Cannon required the party to rotate, then rotate back immediately to make the following monitor movement easier. The highest priority blue tether should run to the front of the boss to pop their tether.
- Once the monitors appear, the two players at the front of the boss rotate to
the side with the monitors and use
Diamondback while everyone else rotates to the safe side. If the MT is one of the baiters they can mitigate using
Dragon Force and
Chelonian Gate instead.
- After the tankbuster hits, break the remaining blue tether.
- Once the magic vulnerability debuff falls off, break the remaining green/red tether. The person with the green/red tether that did not bait a monitor will need to run towards their partner to pop the tether, as their partner will probably still be in Diamondback.
Omega will finish Patch with Ion Efflux, a heavy-hitting raidwide AOE. Use
the usual mitigations of
Bad Breath,
Addle,
Magic Hammer and
Gobskin to survive. The timing can be
tricky since if the last tether of Patch detonates too late, you will still have
the magic vulnerability debuff when this goes off and die.
Hello World 1
Right after Ion Efflux, Omega will begin casting Hello World. This is also a pretty heavy raidwide, so heal up and mitigate appropriately. This is a somewhat notorious mechanic, but it’s not terribly difficult once you understand all the components.
Once the cast finishes, a bunch of debuffs will go out:
- One person receives Critical Overflow Bug (COB), which is a large AOE (about the size of the arena) that applies a magic vulnerability debuff and the COB debuff itself to anyone that gets hit (but they do not receive the debuff if they’ve already had it before).
- Three people receive Latent Defect. When this debuff expires, the target dies. It can be cleansed by taking damage from the other Hello World debuffs, and we will use COB to do so.
- Two people will receive Critical Synchronization Bug (CSB), one will have an 8
second duration and the other will have a 12 second duration. This is similar
to Shared Sentence in A12S; it is a heavy-hitting shared-damage AOE that we
will mitigate using
Diamondback.
- Two people will receive no debuff.
Essentially what needs to happen is everyone will receive the COB debuff at some point, we want no one to have it when Critical Error gets cast (a moderate raidwide which applies the debuff to anyone that hasn’t had it yet), and we want as few people as possible to actually receive it from Critical Error. Here is a toolbox for the mechanic. The resolution for each debuff, based on whatever you received initially, is as follows:
- Critical Overflow Bug runs straight south. After their COB goes off, they run back to the north (“D” marker in toolbox) and wait.
- Latent Defect players run to the south to cleanse their debuff with the initial COB (and receive COB at the same time). These players should form a short line at the south to indicate where they’re going next, as the subsequent COBs will go to the west, east, and south.
- Critical Synchronization Bug players will run to the north and take their
damage solo with
Diamondback. The short (8 seconds) debuff should go to the “1” marker from the toolbox and the long (12 seconds) debuff should go to the “2” marker from the toolbox. The short debuff may need to use
Swiftcast to mitigate the damage in time. After these players receive COB from Critical Error, they will bring their debuffs to the west and east based on whichever side they took their CSB debuffs (12 west, 8 east).
- No debuff will wait north (“D” marker from toolbox) and indicate if they intend to go east or west by leaning slightly in that direction. Once the Latent Defect players receive their COB debuffs, the no debuff players will move towards the east or west COB player to pick up the debuff when it detonates. Once they receive the debuff, they just drop it in the east or west (wherever they are) and finally return back to the north.
There is a ton of damage going out during this and it’s ultimately
everybody’s responsibility to heal themselves and their neighbors with
White Wind. The MT will still be taking auto attacks during this entire
mechanic, so it’s important to watch their health as well. For COB debuffs, if
you start casting White Wind when there is about one second left on the debuff
then you will snapshot yourself at full health and fully heal yourself. This
does take some practice and depends on things like ping and spell speed, but if
you can’t get the timing down you can just cast White Wind twice and be fine.
The “no debuff” players will take the most damage as they get hit by the Latent
Defect COB buffs, their own COB buffs, and Critical Error. There is plenty of
time for everyone to return to the north during the Critical Error cast to
receive heals, and mitigating the Critical Error cast is extremely helpful.
Once all of this is done, Omega will follow up with Ion Efflux again, so heal up and mitigate as before.
