Avatar of the Serpent. As a bonus action you may speak a command word and throw this shield to an unoccupied space within 30ft. of you. The shield transforms into a Giant Poisonous Snake. The snake has an amount of hit points equal to 5 times your character level and rolls its own initiative. When the snake is reduced to 0 hit points, or after 1 hour has passed, it turns back into a shield. You retain the effects of Ward of the Fang as long as the snake is within 200ft. of you. You can use this feature once per day.
