Serpents Fortitude

Once per long rest, after you are below half of your max HP, you spend your bonus action transforming into a Giant Constrictor Snake, all worn or carried items are absorbed into this form and can not be used. While in this form your Intelligence and Wisdom stats remain the same if you had the ability to cast spells you are still able to do so, and you maintain this form until dispelled or this form is dropped to 0 HP at which point you will revert to your original form and any extra damage is carried over.
