Stone of Monkey Business (5e Equipment)
From D&D Wiki
Wondrous item, uncommon
This stone has a smooth, yellowish-grey surface. If you use an action to speak the command word and toss the stone to a point on the ground within 10 feet of you, the stone becomes a living beast as dictated below. If the space where the creature would appear is occupied by other creatures or objects, or if there isn't enough space for the creature, the stone remains dormant.
This creature acts independently of you, but it always obeys your spoken commands. It understands, but does not speak, Common. In combat, it rolls its own initiative and acts on its own turn.
It reverts to the stone early if it drops to 0 hit points, if it is otherwise killed, or if you use an action to speak the command word again while touching it.
The stone has three charges, and regains 1d3 - 1 expended charges daily at dawn. While in creature form, the stone does not regain charges. It can be used to summon the following: monkey (1 charge), ape (2 charges), dire ape (3 charges). If you expend the last charge, roll a d20. On a 1, the creature becomes wild and no longer obeys commands.
Monkeys created by this stone are able to use magic items (provided that the item can be worn or held by a tiny monkey), but can only attune to one. This does not count towards your attunement limit. Class, level, race, and any other prerequisite still apply.
