This dark grey cloak is made of cured Basilisk skin. As an action, you can command the cloak to transform you into a Basilisk for up to 1 hour. The transformation otherwise functions as the polymorph spell, but you can use a bonus action to revert to your normal form.
Curse. This cloak is cursed with the essence of a Basilisk, and becoming attuned to it extends the curse to you. Until the curse is broken with remove curse or similar magic, you are unwilling to part with the cloak, keeping it within reach at all times.
The sixth time you use the cloak, and each time thereafter, you must make a DC 15 Constitution saving throw. On a failed save, after the transformation ends you suffered the effects of Petrifying Curse, and your body begins to petrify while your skin hardens. You will recive +1 to your Armor Class, -1 to your Dexterity Modifier and your moment is reduced by 5 feet, this effects cumulates and after reciving 4 charge user becomes Petrified. Each of the 4 minor charge can be removed by lesser restoration or remove curse spells, but from the Petrified condition user can be only freed by Greater Restoration. If you remain in this petrified form for 6 days, only a wish spell can reverse the transformation.
Notes: Buff, Shapechanging, Cursed
