Critter’s Call

You summon one Tiny Beast with a Challenge Rating of 0 that moves within range in 1d10 minutes. The DM chooses a Beast appropriate to the current environment. The Beast is friendly to you and your allies and obeys your commands as best as it can. You can ask it to perform simple tasks such as guarding a designated area, alerting you to intruders, or entertaining an audience.

The Beast is not a familiar and cannot communicate telepathically. Its knowledge and awareness are limited by its low Intelligence. Spells and effects that specifically target familiars do not affect this creature. In combat, the Beast cannot attack or take the Help action, but it can take other actions as normal. It takes its turn immediately after yours.

You can only have one summoned friendly critter at a time. If you cast this spell while you already have one, the spell ends for the previous beast. The spell also ends if you or your companions harm the Beast, if the critter cannot find a path to you when summoned, or if you and the creature become separated by more than 500 feet.

When the spell ends, the beast becomes Frightened and attempts to flee from you by the quickest and safest route available.

Cantrip Upgrade. 5th Level: The duration increases to 8 hours. 11th Level: The duration increases to 24 hours. 17th Level: The duration increases to 7 days. During this time, you can attempt to domesticate the creature using Animal Handling checks (DM's adjudication). On a successful check, the creature remains beyond the spell's duration and becomes a loyal companion.
