What fixed it for me was the removal of Unending Thaw perk. I tried putting it on again, then the ice storm bugged again, very easily recreatable bug. I took all the ice storm talents.
on a side note, pillar of fire still cast on self, but less often from before 1.0.5, doesnt really matter whether weapon sheathed or unsheathed
I don’t have unexpected issues with my ice gauntlett and fire staff (I have an issue only once in stairs with fire pillar)
But as we cannot stack DoT aoe anymore (ice storm, and burn area on fire pillar et Fire ball) these skills won’t do any damage is there is another mage with you
This bug is happening when completely solo. Just me and the mobs. Keeping Unending Thaw off gear has helped, but any cast of Ice Storm is still hit and miss.
I suppose this is a good point for other Ice Gauntlet users. Avoid Unending Thaw gear.
