Bone Cage

Armor (breastplate), unique (requires attunement by a fighter or rogue)

The bones of the damned are ghoulishly grafted into this charred black +2 breastplate.

Radiates: Abjuration and necromancy magic.

Power: This armor has no weight; you can add your full Dexterity modifier to your AC.

Power: You gain immunity to piercing and poison damage and to the poisoned condition. You suffer vulnerability to bludgeoning damage.

Power: Skeletons and skeletal creatures of CR 4 or less ignore you unless you attack them first.

Power: You gain advantage on Charisma checks against necromancers, undead, and warlocks.

Power: You may cast animate dead (skeletons only) as a bonus action a number of times per day equal to your proficiency bonus. You do this by ripping a bone from your armor and throwing it up to 30 feet away into an unoccupied square. The bone immediately grows into a skeleton under your control, complete with your choice of shortbow or shortsword. If destroyed or the duration ends, you may retrieve the bone and return it to your armor.

Special: If you are a rogue, you gain proficiency with this armor.
