When the caster points at a living creature in range, the subtle balances that maintain it are disrupted. The creature begins to melt from the inside out taking 1d2 +1 HP per level of the caster acid damage. At the start of the creatures turn, it makes another saving throw, if it fails the spell continues and it takes damage again.
