Bone Collective 2014
CR 8 undead
Small undead, Chaotic Evil
The collective’s individual bones are connected via a hive mind. It can telepathically communicate with any of its individual bones within 50 miles of it, and it can’t be surprised. If the collective is reduced to half its hp or fewer, its Intelligence score is reduced to 1, it can’t cast spells, it immediately changes to its shapeless form, and it can’t take on a Humanoid form.
The bone collective can wield weapons and hold, grasp, push, pull, or interact with objects that might otherwise require a Humanoid form to accomplish.
The bone collective can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a Tiny bone.
The bone collective doesn’t require air, food, drink, or sleep.
When the bone collective hits a poisoned creature with a Bite or Piercing Bones attack, the target’s Charisma score is reduced by 1d4. The target is incapacitated if this reduces its Charisma to 0. The reduction lasts until the target finishes a long rest.
