02:19 Phase 2
03:25 NIKKE gears
always clear off her circles, if you miss it, she will cast rocket barrage
always go for cover during her fire breath to avoid the DoT
the fireballs at 00:48, if you can tank that, you can shave some time for dps instead of going for cover
For phase 2, try focus fire to destroy 1 head, you can see at 03:05 once 1 head gets destroyed, 10x health bar is deducted.
Good luck!
