Strategy

The good news is that players looking to only solo-MVP will not have to factor in Dimensional Cleave, as Colossus Omega usually does not enter Overdrive until near halfway. This also makes Break and Overdrive Assassin characters less than ideal for this fight, so plan accordingly if you're only after red boxes.

This does not make Colossus Omega any less of a challenge for newer players, however, as of the four "standard" element omega bosses it is considered the hardest and for good reason. Its basic attack will always be a brutally powerful single hit, so heavy attack downs and strong blinds are valuable. The charge attacks can be thought of as "mode changes": Shelter doesn't inflict much damage and actually lessens the power of its normal attack but makes the boss very tanky (especially against Water, although Dispel will remove the resist first) while Resolute Reactor's Burn and Attack Up will quickly drain lifebars but the self defense down makes it the perfect time to unleash a full chain. This is all it does for the first half of the fight, so react accordingly to the charge attack it uses and grind it down to half HP.

The second half of the fight is all about dealing with the dreaded Dimensional Cleave, which nukes the unfortunate target for over 60k damage. Needless to say, this will kill the target without some form of defense. You'll need AT LEAST 90% damage cut against fire (or preferably 100% cut) or a dodge to survive, and due to the potential for constant triggers you should be prepared to lose units anyways. It can also be worth it to save a full chain of charge attacks until it nears a trigger to try to skip as many as possible. Without either Yngwie, Lily, Garuda summon, or Holy Saber, you should be prepared to call for help if the wrong unit takes a Dimensional Cleave to an undefended face.

Strategy

  • Dimensional Cleave has gone from "Massive Overkill" to simply "One Hit Kill without mitigation". Going for the Arm first helps to prevent this in two ways: As you're killing the Arm to stop the Cleaves altogether, activating its Heat triggers clears diamonds. You get two clears this way and should be able to get a Break before it can refill after the second Heat.
  • As with the other Impossible Omega raids, the fight calms down a bunch once the add is dead. Just don't carelessly auto into Resolute Reactor at the end.
