A forest drake can, as a standard action, spit a ball of acid that bursts into a cloud on impact. This attack has a range of 60 feet and deals acid damage (Breath save halves) to all creatures within the resulting 10-foot-radius spread. The cloud remains for 1d4 rounds once created, acting as a 10-foot-radius obscuring mist (it no longer causes damage), but a strong wind disperses it in a single round. Once a forest drake has used its acidic cloud breath, it cannot do so again for 1d4 rounds.
