Sourcebook: L’Arsene’s Ledger

You attempt to turn the skin of a creature you touch into bony plates. If the target’s body is made of flesh, it must make a Constitution saving throw. A willing creature can choose to fail this saving throw. On a failure, a creature’s skin turns into hardened, articulating plates of bone. For the duration, the creature’s speed is halved, it has disadvantage on Dexterity saving throws, and it has resistance to piercing and slashing damage.
