i’ve been thinking of trying wiz1>pyro2>kino3>featherfoot3. enervation would work really nicely with heavy gravity + flame ground. levatate would also keep it safe. and kundela slash + curse + 2x debuff on boss is incredible single target dps. i can’t decide if pyro2>kino3 would offer enough aoe dps though. it’s also tempting to drop pyro 2 and take thuma c1 instead. magnetic force > shrink body for easy +120% damage debuff. then kundela slash them while they’re gathered.
IIRC, FF have aoe attack limit so the gathering from psy would not be effective. If you change to linker , you would have the gathering effect but the damage would be many times better.
I think the developers made the psy have synergic skills with enchanter. Not just saying about the gathering thing, the enchanter attribute to specifically work with psy’s skills. With one rank for cryo it might be pretty good
