This varying-sized cannon can be used to rain varying-sized ordinance down on your enemies. It appears to be a golden cannon barrel mounted on a steel- and wood-wheeled frame.

When you first acquire the cannon, it's at its normal Tiny, 5-pound size. As an Action, you may utter a command word choose to increase the cannon's size for 1 minute to Small (40-pound), Medium (320-pound), or Large (2580-pound) size. The cannon can be fired while held in hand if you can carry it, otherwise you can place it on a surface that can support the size you wish the cannon to be. After 1 minute or when you utter the command word again, the cannon returns to Tiny size.

The cannon contains 8 charges and regains all spent charges after a long rest. As a Bonus Action, you spend charges to fire the cannon at your enemies. The number of charges spent and the damage dealt changes based on the size of your cannon.

Tiny Cannon: spend 1 charge to fire; +6 to hit, damage equals (2d4 + your proficiency bonus) bludgeoning damage.

Small Cannon: spend 2 charges to fire; +7 to hit, damage equals (4d6 + your proficiency bonus) bludgeoning damage.

Medium Cannon: spend 4 charges to fire; +9 to hit, damage equals (6d8 + your proficiency bonus) bludgeoning or fire damage.

Large Cannon: spend 8 charges to fire; +10 to hit, damage equals (8d10 + your proficiency bonus) bludgeoning, fire, or force damage.
