Bio (3.5e Spell)

''The dragon suddenly felt a terrible pressure in its body, as weeping green pus erupted from its pores. What had that caster done to him?!''

You call up deadly venom within the body, damaging it from within. The target must save vs poison, or take 1d6 points of damage per caster level (maximum 10d6), Fortitude for half damage. If they failed, the next round they must make another saving throw or lose 2 points of constitution as well. Immunity to poison makes the creature immune to this spell.

Material Component: Crushed bodies of various toxic insects
