Bag of Goats

This appears to be a simple leather bag with a string to tie it closed. Inside are 7 of furry balls. As an action, you can reach your hand into the bag and pull out one of the balls and roll it onto the ground. When the ball stops rolling it transforms into a goat with AC 15, 29 HP and a passive Perception of 20. It is medium You can forgo your turn to let the goat attack. On a hit it does 2d10 + your proficiency bonus.

The goat will attack everyone except the summoner. This can only be remedied by inscribing a control rune from a set of runecarver's tools on the bag, at which point you may select 5 creatures that are not affected by it. The goat will follow the summoner anywhere.
