Hi. I'm trying to master frost mage, and while it tons of fun, I cannot help but get myself killed rather quickly. Is there any healing or protecting spells I could use, like priest ones? So far the only unit who can heal hero sustainably more or less is armored packbest, and even then it's written than it's only heals "adjacent" allies... which I suppose aren't everyone but oonly those who are by both side of this unit?
