So I’ve tried using psyche with both Truffle and Fushu. I have invested a bit more into Truffle and because Truffle is healing large chunks of Psyche’s hp, she doesn’t need to consume as much sanity and can stay in her Flamboyance state.
It does need careful management as casting her skill too many times drains sanity too fast.

I will say I will use psyche, truffle and filbert and fina for the high damage and don't use fushu you can't use psyche when you had full sanity because of the damage you do gets even low after clicking too much her skill then using normal skill damage on the enemy
