For my second playthrough (no WM 1 and 2 yet), I was going for a Russian theme with my pc and a couple custom companions. One was a pale-elf druid who could turn into a bear and was focused around freeze damage. 15/9/10/17/18/9 stats. But while winter wind was pretty solid I found that past the first tier druids were very lacking in good ice spells. Are wizards simply better equipped at dishing out that damage type? What talents would be best for a wizard/druid specialist in ice nukes?
