Dragon's Animated Siege

You channel the draconic spirit into a group of small objects, causing them to animate and fight by your side. Choose up to eight Tiny or Small non-magical objects within range, be it rocks, blades, or even miniature siege weapons. Each object becomes a creature under your control, gaining an AC of 18 and 30 hit points, and its damage type changes to fire, lightning, or acid, depending on your choice.

As a bonus action on your turn, you can command the objects to move up to 30 feet and take an attack or take the Dodge action. They can use the Attack action to make a ranged attack with a range of 30/120 feet, dealing 1d10 + your spellcasting ability modifier damage of the chosen type. Alternatively, they can make a melee attack with a reach of 5 feet, dealing 1d4 + your spellcasting ability modifier damage of the chosen type. If they attack a target, they roll their damage separately, but multiple animate objects can attack the same target.

The animated objects have a movement speed of 30 feet and can hover if they were designed to fly. They can also take the form of miniature siege weapons, such as ballistae, trebuchets, or cannons, dealing massive damage at the cost of mobility. If you command them to do so, they can form a barricade up to 10 feet long, 5 feet wide, and 5 feet tall, providing half cover to you and your allies.

When you cast this spell using an 8th level spell slot, you can animate up to ten objects. When you cast this spell using a 9th level spell slot, you can animate up to twelve objects, and the damage dealt by the animated objects increases by 1d10.
