So having gotten him on the last week, does anyone have any advice on talisman selection?

It would seem he could be a good alchemist replacement, but his green slots means angel is out of the question. Is it worth going immunity talismans, maybe with a magic cosmos + 3 greens or 2 greens and random blue? Or is it a case of going blues + green 2 setters and rely on someone else removing his stun?

Also is he worth skill sharding asap? Seems his power move without shards is pretty low damage?
