Amulet of Ooze Control (5e Equipment)

Wondrous item, very rare (requires attunement)

While you are attuned to the amulet, ordinary oozes are indifferent towards you and will not attack you unless you threaten or harm them.
The amulet has 3 charges. Whenever an ooze that isn't under another creature's control comes within 30 feet of you, you can expend a charge as an action and make a Charisma check contested by the ooze's Wisdom check. If you lose the contest, the ooze behaves as it normally would and can't be swayed by the amulet's magic for the next 24 hours. If you win the contest, the ooze is swayed by the amulet's magic and becomes friendly to you and your companions for as long as you maintain concentration, as though you were concentrating on a spell, for a maximum of 1 hour. A friendly ooze obeys your commands. If you issue no commands to a friendly ooze, it defends itself but otherwise takes no actions. If a friendly ooze starts its turn and is further than 30 feet away from you, your control over that ooze ends, and the ooze behaves as it normally would and can't be swayed by the amulet's magic for the next 24 hours.
The amulet regains 1d3 expended charges daily at dawn.
