Ring of the Excited Serpent

Due to this item's size it is classified as a ring, however, it functions more like a collar. The ring is white in color and has a black stripe in the center that comes to an hourglass like design in the front.

While attuned, once per day this ring can be activated to place the wearer into a state of excitement for 1 hour. While excited, the wearer grows 2 sizes and now has the stat block of a corresponding creature. (ex. a poisonous snake becomes a giant poisonous snake. etc.) 

Notes: Can only be attuned by a legless creature of size small or smaller.
