Wand of Centipede

Wand Uncommon (this item requires attunement)

This wand is crafted from dark wood, and carved to appear finely segmented. While holding it, you can use an action to speak its command word, transforming it into a giant centipede. The creature acts on its own initiative count and follows your mental commands. The wand returns to its normal form when you use a bonus action to speak the command word again, or if the creature is reduced to 0 hit points.
