Warband With a Frozen Theme

This teen frost-blasting witch is getting some minions in the shape of snow goons (run, Calvin, run...).

I think they should be immune to cold-based, but vulnerable to heat/firebased attacks, which should cancel each other out, points-wise.

I have two more of these 'Copplestone Collection' minis, and as rather lowly characters, I should have plenty of XP to make the witch a formidable foe for the Monsters.
