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.
