Created by the Eldritch Cannon subclass feature.

Activate Cannon (Requires You to be within 60 Feet of the Cannon). As a Bonus Action, you order the cannon to use the Flamethrower, Force Ballista, or Protector option below; you can direct the cannon to move up to 15 feet before or after that option:

• Flamethrower. The cannon blasts fire in a 15-foot Cone. Each creature in that area makes a Dexterity saving throw against your spell save DC, taking 2d8 Fire damage on a failed save or half as much damage on a successful one. Flammable objects in the Cone that aren't being worn or carried start burning.
• Force Ballista. Make a ranged spell attack originating from the cannon at one creature or object within 120 feet of it. On a hit, the target takes 2d8 Force damage, and if the target is a creature, it is pushed up to 5 feet away from the cannon.
• Protector. The cannon emits a burst of positive energy that grants itself and each creature of your choice within 10 feet of the cannon a number of Temporary Hit Points equal to 1d8 plus your Intelligence modifier (minimum of +1).
