Actions

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).
