Mythic Adventures | Monsters | Dragon | Black | Mythic | Special Abilities | Corrupt Water
Once per day, a black dragon can stagnate 10 cubic feet of
still water within 210 feet, making it foul and unable to support
water-breathing life. The ability spoils liquids containing
water. Liquid-based
magic items (such as potions) and items in a creature's
possession must succeed at a Will save (DC 21) or become ruined. This ability is the equivalent of a 1st-level spell.
