6th-level transmutation (dragon)

Casting Time: 1 action
Range: Self
Components: V, S
Duration: Concentration, up to 1 minute

You take on some of the physical characteristics and abilities of the cave dragon, growing protective scales and claws. Until the spell ends, your AC can’t be lower than 16, regardless of what kind of armor you are wearing. You gain blindsight out to a range of 60 feet. You can take two actions on your turn to attack with your claws, dealing 1d6 slashing damage on a hit. You have resistance to poison damage. Up to three times while the spell is active, as an action, you can breathe a 20-foot cone of poison gas, dealing 6d8 poison damage to each creature in the cone and making it poisoned until it finishes a long or short rest. A creature that succeeds on a Constitution saving throw takes half as much damage from your breath weapon and is not poisoned. Finally, you gain a climbing speed of 40 feet.
