Darkmantle

Darkmantles are small, flying predators living in caves, hunting by using camouflage and magical darkness to surprise, envelop, and crush their prey.

Attracted by sound, these creatures cling in wait upside-down on the tunnel's ceiling, appearing as stalactites to unwary prey. Dropping down and opening up like an umbrella, these creatures clamp down onto the heads of their victims.

Appearance

Abilities
