Give Singularity Reactor an item level sync

I just don't like how we get the boss to 1% & continue to wail(?) on him for 30 secs until he finally starts his ultimate sequence

I kinda think it's funny how we can't sequence break the fight since a recent run had him at 0% for like a minute before he went into the mechanic fest portion of the fight.
