I had fun with the CryoCannon on my last multiplayer run. Couldn’t put it all together since my partner was Dark Urge origin, but still effective. I’d only run Storm Sorcerer before and I didn’t find myself twinning spells a lot with that one. Felt like I was making better use of my sorcery points with this build.
My favorite build is an elemental damage critical hit build. It essentially simulates the tabletop experience of throwing piles of dice on the table per attack. I just put up a guide for it in the community (hopefully it’s not out of date with the new patch).
