You target a creature you can see within range and summon a miniature version of that creature in the nearest unoccupied space to them. The miniature creature is exactly half the size of the target and has 10 hit points with an AC of 12. The copy of the target cannot use spells and is equipped with miniature versions of the targets weapons, sharing the same hit roll modifier, but doing half damage (minimum of 1). The copy disappears when it drops to 0 hit points or when the spell ends.
The miniature creature is friendly to you and your companions for the duration. Roll initiative for the creature, which has its own turns. It obeys any verbal commands that you issue to it (no action required by you). If you don't issue any commands to the miniature creature, it uses the dodge action, but otherwise takes no actions.
If your concentration is broken, the miniature creature doesn't disappear. Instead, you lose control and it becomes hostile toward you and your companions. An uncontrolled miniature creature can't be dismissed by you, and it disappears 1 minute after you summoned it.
