Vomit Scrap (Recharge 5-6)

The rust drake vomits forth a 15-foot cone of rusted metal. Each creature in the area must make a DC 15 Dexterity saving throw, taking 22 (5d8) slashing damage and 22 (5d8) poison damage on a failed save, or half as much damage on a successful one. In addition, each creature that failed the saving throw must succeed on a DC 15 Constitution saving throw or contract the rust drake lockjaw disease (see the Rust Drake Lockjaw trait).
