While wearing this ring, Phil can speak its command word as an action to summon 1d4 of a particular Ooze Creature (Summoner rolls 1d4 to determine the amount of oozes summoned and then rolls 1d4 and consults the following chart: 1 - Ochre Jelly, 2 - Gelatinous Cube, 3 - Ochre Jelly, 4 - Black Pudding)

The Ooze appears in an unoccupied space Phil chooses within range of 80 feet. It remains as long as he concentrates (as if concentrating on a spell), to a maximum of 1 hour, or until it drops to 0 hit points. It then returns to its home plane.

While summoned, the Ooze is friendly to Phil and his companions. It obeys any commands it is given, and if Phil fails to command it, the Ooze defends itself against attackers but takes no other actions.

The ring has 6 initial charges. Once the last charge has been used, roll d20. Anything below 10 and the ring disintegrates. Otherwise the ring restores 1d4 charges. It also grants the wearer advantage on all saving throws against Ooze creatures.
