Tiny Summons

You summon a tiny fey or fiend creature in the form of a beast with a CR of 0. The summoned creature disappears when it drops to 0 hit points, when you dismiss it as an action, or when the spell ends. The summoned creature is friendly to you and your companions. The Dungeon Master has the creature's statistics.

You can cast this spell multiple times to have up to three creatures summoned from this spell. 

These creatures cannot carry items, attack or help, but can take all other actions as normal. In combat,  the summoned creature rolls its own initiative and acts on its own turn. If you have multiple summoned creatures, they all act on the same initiative. Any creature summoned can obey any simple verbal commands that you issue to them (no action required by you).

If you don’t issue any commands to them, they will not perform any actions and will not move.
