A second set of Magitek Bits will spawn, and shortly after, Six ships will crash and damage with Freefire. Your best bet to avoid this is to run to the center? (Unsure. a few of us died, so I don't know the proper way to mitigate this.) Kill the bits.

The last thing Ultima does is cast, well...Ultima. Deals approx 30k damage to everyone. Again, we sort of died here. Not sure how to get past this.

I hope this helps you all out with the fight. Best of luck.

A pox upon the 1000 character limit. For shame!
