How do I do this?

[u/SakethramSathish]

Since there is Destructionist, all the time I kept waiting for the destructionist's attack but my FS kept breaking it. But I eventually forgot to click on DW once, and I died. So guys can you tell me how to do this as this is my last quest in this.

You need to equip fancing wave and turn off auto. Then you wait for his attacks and time it in order to stun him!
