Blizzard

Spell Type: Attack; Mana Cost: 20+ MP; TN: 17
Test: Dexterity (Acrobatics) vs. Spellpower; Requirements: Cone of Cold

This spell conjures forth a blizzard with a 30 foot radius, centered anywhere within 100 feet. Anyone in its howling winds takes 2d6 + Magic penetrating damage and must succeed at a Dexterity (Acrobatics) test vs. your Spellpower or slip and fall prone on the accumulating ice. Targets that start their turn in the blizzard take an additional 1d6 penetrating damage and must make an immediate test to avoid falling prone. All melee attacks made into or from the blizzard suffer a -2 penalty, all such ranged attacks suffer a -5 penalty. This spell normally lasts for one round but for 10 MP, paid at the start of your subsequent turns as a free action, you may extend the duration by an additional round.
