This Arknights Boss is So WEAK Not Even His Immunity Can Save Him (RS-EX-8 CM) 

irrc u need a really fast burst to "ignore" his 2nd phase mechanic, buffer/de-buffer might be needed on this

After his phase 2 begins, let him normal attack 4 times and wait just a little bit more (may need a multiple tries to get the timing). There is a small window where his hp-gating can't activate because he's in the middle of using the brazier-extinguisher skill.
