As we do these raids more, many of us are having fun finding new strategies to beat the boss in as few turns as possible. I found this strategy effective on Sino tonight:
2 Irritators, 2 Indominus Rex 2
Irritators: RTC, SS, GT
Indom1:Cloak, APR, MF
Indom2:MF, Cloak, APR
3 turns, the boss was defeated.
