interrupting skill to sapphire roga

since no one share it here (or maybe I'm just stupid), I'm just gonna write it here.
Sapphire roga (lvl 181)
Purple mode (normal mode) - any interruption make the boss change to green mode, counter to flinch
Green mode (crit resist mode) - any interruption make the boss change to red mode, counter to tumble
red mode (high def/resistance?) - any interruption make the boss change to purple mode, counter to stun

green mode make the boss resistance to critical. but when i attack it, it's like I'm doing critical damage to boss but the number colour is white (don't know it's a bug or it's defence/resistance became lower)
just tested on normal difficulty.

 

You can try throwing a cat on that and just bombard it with elemental debuffs.(feel free to correct me if im wrong tho lol)

 

you mean deal ailment to it will change the boss phase?
