Rod of Summoning Ooze - D&D5e (Patreon)

Rod, very rare (requires attunement)

___

This magical rod is crafted from metal, specially treated with a unique alchemical preparation made from the potent spittle of a black dragon. This process renders the metal extraordinarily resistant to the corrosive power of acid, making it both durable and resilient. At its base, an enchanted yellow diamond gleams adding a touch of enchantment to its already impressive design.

The head of the rod is fashioned from shattered fragments of black dragon bones, it partially encases an enchanting, fluid-filled sphere of potent acid. This liquid dances within the confines of the bone, moving with an almost lifelike grace.

The Rod of Summoning Ooze holds 7 charges and regains 1d6 + 1 expended charges daily at dawn.

Summon Ooze. As an action, you can expend one or more of the rod's charges to summon a Gray Ooze for each charge spent. The summoned Ooze appears in an unoccupied space within 60 feet of you.

Call of the Cube. By channeling the rod's power, you can expend an action and 6 charges of the rod simultaneously to call forth a Gelatinous Cube. The massive entity manifestsin an unoccupied space within 60 feet of you, pulsating with an insatiable desire to engulf anything in its path.

The summoned creatures regard you as an ally and will fight by your side. In combat, they share your initiative count but act right after your turn. These creatures heed your verbal commands, no action required. If not given any instructions, they instinctively take the Dodge action and move to avoid threats. The creatures vanish in a pool of acid after 1 hour, you dismiss them, or they are destroyed. Any creature that moves to the pool of acid for the first time on a turn or start its turn there takes 2d10 acid damage.

Curse of Corrosion. Should you expend the rod's final charge, roll a d20. On a result of 1, the rod  starts to corrode rapidly, dripping with acid, until it disintegrates, leaving nothing but the stench behind.
