Armada Cannon

You create a mold of energy that forms into a large cannon in an unoccupied space you see. The cannon takes up spaces as if it were a large creature, but any creature can walk through its space as if it were difficult terrain. The cannon counts as a Construct creature, it has 20 hit points and an Armor Class of 15. When a cannon is reduced to 0 hit points it breaks in pieces and disappears. The cannon itself cannot move once placed. On your turn, with a bonus action, you can command the cannon to make a ranged attack (in a 90 degree cone at which it is facing) using your spell attack modifier. The cannon has the loading property and can only make one attack per round regardless of how many bonus actions you use. While the cannon is not occupied by at least two enemy creatures it can circle on its axis with the same bonus action. Its movement is further restricted when it is placed on difficult terrain, grappled, incapacitated, paralyzed, petrified, restrained or stunned. The attack it can perform is dependent on the type of Armada Cannon you create, if you can hit more than one creature you roll a single attack roll for all creatures.

• Cannon Armada: 1 creature, 150ft. range, 3d8 (+ spellcasting ability modifier) bludgeoning damage.
• Scatter Armada: 15ft. cube, 60ft. range, 2d8 fire damage.
• Grenadier Armada: 20ft. sphere, 90ft. range, 1d10 (+ spellcasting ability modifier) fire damage.
• Wave Armada: 20ft. cone, 4d6 thunder damage.
• Bounce Armada: 1 creature, 120ft. range, 1d12 (+ spellcasting ability modifier) bludgeoning damage. If this projectile reduces a target to 0 hit points, it can bounce to a nearby enemy creature of your choice within 10ft. of the target for another 1d8 (+ spellcasting ability modifier) bludgeoning damage.

You can also create your own Armada at your DM's discretion.

When casting this spell at 4th-level or higher, you gain an additional 5ft. range on your initial spellcasting and you can create one additional Armada for every spell level above 3rd. The Armada don't have to be the same type, but have to be within 15ft. from each other at all times. You can command all Armada's with the same bonus action.
