That spell is really meant for LA Atlantis I believe and for LA Atlantis I find hidden in snow to be a great spell. For undead they have great stats. Above average hitpoints, high magic resitance, high defense and a cold aura. And you can cast it using water gems instead of death gems. There is a lot more use for death gems then water, so that in itself is a bonus. Combine them with darkness, wolven winter, and cold fatigue spells, and they do great.
