1/day: Overbreathing: The Cassiter may enter an Overbreathing state for 30 seconds when threatened. While Overbreating, the Cassiter may add their Constitution to saves and checks involving Constitution, Strength, and Dexterity as well as Attacks or Spell Casts. The Cassiter may extend Overbreating at the cost of suffering 2 levels of exhaustion.   Noxious Spray: While Overbreathing, the Terssiter may spray a cloud of noxious aerosol in two 15 foot cones. Creatures caught in the spray must make a save equal to 10 + (Terssiter Hit Dice / 2) + 4. On a failed save, sprayed creatures will take (1+(Terssiter Hit Dice/2))d4 damage, half as much on a successful save. Affected creatures must then make a the above constitution save once more against inhaling the poison, failing this save will inflict two levels of exhaustion.
