ToME: the Tales of Maj'Eyal

Hi,

While in shivgoroth form i dont get healed by cold damage I do for instance by Ice Storm. In the log i see cold damage done but it does not heal me.

You get healed when you take cold damage, not when you deal cold damage, and you can't hit yourself with Ice Storm. Double check by casting Glacial Vapour on yourself?

I've recently played around with cold magic and for me it did work as advertised.

Like donkatsu said, you get healed by cold damage to you, not by dealing out cold damage. Ice storm doesn't damage you, as you can see when you cast it near the end of your shiv form duration so it goes on a bit longer.
