Whip of the Snake

As an action you can change your whip into a
6 foot long, bright green shimmering boa
constrictor. As a snake, if it takes 2 or more
damage the snake turns back into a whip and
can't change back until the next dawn.
It costs an action to change it back into a whip.
It has a bite attack that on a hit (+5)
does 1hp damage.
