Dankwood Hag

The hag can breathe air and water.

The hag can mimic animal sounds and humanoid voices. A creature that hears the sounds can tell they are imitations with a successful DC 14 Wisdom (Insight) check.

The hag's spellcasting ability is Charisma (spell save DC 12). It can innately cast the following spells:

At will: dancing lights, minor illusion, vicious mockery

The hag covers herself with a magical illusion that allows her to look like another creature of her general size and shape. The illusion ends when the hag chooses, or if she dies. A DC 20 Intelligence (Investigation) check will expose the hag's disguise.

The hag magically turns invisible until she attacks or casts a spell, or until her concentration ends. While invisible, she leaves no physical evidence of her passage, and can only be tracked by magic.

Melee Weapon Attack: +6 to hit, one target. Hit: 17 (2d8 + 4) slashing damage.
