Virulent Walking Bomb

Spell Type: Attack; Mana Cost: 13 MP; TN: 17
Test: Constitution (Stamina) vs Spellpower; Requirements: Death Syphon

You infect the blood of a target within 20 feet with deadly magical venom. When first cast, this spell immediately deals 2d6 + Magic penetrating damage. The subject must then make a Constitution (Stamina) test vs. your Spellpower at the start of each of its turns. If it succeeds, the spell ends. If it fails, the target suffers another 1d6 + Magic penetrating damage. If the target dies while virulent walking bomb is still in effect, it explodes in a shower of gore, dealing 2d6 damage to anyone within 15 feet. Subjects caught in this blast must succeed at a Constitution (Stamina) test vs. your Spellpower -2 or become secondary targets of this spell, suffering 1d6 + Magic penetrating damage on each of their turns until they succeed on the test. Secondary targets do not infect additional targets.
