The most powerful cold based spell is the spell hailstorm. By tapping into the
arctic plane, a small storm producing hail is formed that swirls around the
target. The hailstones are similar to ice bolts, that they dissipate their
cold energy into the target upon contact. A large number of foes can be caught
in this spell at once. Much concentration and effort is needed to call the
power needed to create such a storm.
