The darkmantle isn't a particularly good climber, but it can cling to a cave roof like a bat, hanging by the hooks at the ends of its tentacles so that its dangling body looks nearly indistinguishable from a stalactite. In this hidden position, the darkmantle waits for prey to pass beneath, at which point it drops and swoops down to attack its victim, slamming its body against the foe and attempting to wrap its webbed tentacles around the target. If the darkmantle misses its prey, it swoops back up and drops again until its prey is vanquished or the darkmantle is grievously injured (in which case the creature flutters back up to the roof to hide and hope its "prey" leaves it alone). The darkmantle's inborn ability to cloak the area around it in magical darkness gives it an additional advantage over foes that rely upon light to see.
