I am thinking of trying the Flicker Frenzy build, looks terrible for Delving but looks like a straight up boss melter. Any thoughts on this build?

Actually played an Oros Flicker Slayer in Flashback. Got rly good equip and for Mapping its pretty super fast.
But even with Slayer overleech it feels a bit squishy and from time to time you get one shot because max 7k life is not enough to survive everything.
Delving is doable. Just switch in Moltenstrike and you do great.

Maybe cyclone

Maybe something shadow but should probably do something fast to compete and maybe make a lil FG in beginning of league and farm enough currency for other toons.

sunderboi

The improved cyclone looks fun, gonna try that

no clue, but probably not something melee
