Due to the magic emanating from these flying cities, the trees below sometimes generate shadowbark: a purple-and-black, moss-like coating that looks like a splotchy bruise.",
    "Any creature that enters a space within 5 feet of shadowbark for the first time on a turn or starts its turn there makes a {@dc 12} Constitution saving throw. On a failed save, the creature takes 5 ({@dice 1d10}) Necrotic damage and can't regain Hit Points until the start of its next turn. On a successful save, the creature takes half as much damage only.",
