A vrock can release a cloud of spores from its body once every 3 rounds. Adjacent creatures take 1d8 points of damage from the spores, plus 1d4 points of damage per round for 10 rounds as the spores grow into thick green vines. Although ugly, the vines are harmless and wither away in 1d4 days if not shaved off before then. The spores can be destroyed by casting bless on the affected creatures or by sprinkling them with holy water. This attack can also be halted by effects that remove or provide immunity to disease.
