Here is an alternative.
Ice pillars is targetable terrain, with crappy Defence.
if you are REALLY good at guessing that 3' gap, you could potentially put down a pillars with a totem, then arc up on the pillars with Raspy, 2 blasts side by side can then reach out a further 10 cm to get someone for what? with touch of winter 5 dmg? do that twice (burning stones) and BHAM, dead 10 wound model.
