Hundreds of tiny cactus needles cover the green Cactus Cloak. When worn, the cloak moves and flows so that its wearer never need fear being pricked by the needles. The cloak acts as masterwork armor spikes, even if the wearer isn’t wearing armor. When used as armor spikes, the wearer gains proficiency in their use. They do 1d6 points of piercing damage (x2 crit) on a successful grapple and count as a light weapon when used as a melee weapon. Once per day, the wearer can whip the cloak in a chosen direction and fire a volley of needles. This volley of needles fills a 30-foot-long cone; all creatures in this area must make a DEX save (DC 17) or suffer 9d6 points of piercing damage. This damage is physical and is subject to damage reduction. Those who succeed at the saving throw take half damage.
Also, by wrapping the cloak about the body, the wearer can assume the shape of a Medium-size cactus; doing so is a standard action. The wearer can remain in cactus form for up to 9 hours. Once deactivated, this power cannot be activated again for 24 hours. The closest inspection cannot reveal that the cactus is anything other than a normal cactus, unless magic such as detect magic or true seeing is used. While in cactus form, the wearer can observe all that transpires around him as if he were in his normal form. The wearer’s hit points and saving throws are unaffected. A wearer gains a +10 natural armor bonus to AC but has an effective Dexterity score of 1. The wearer is also immune to critical hits while in cactus form, and all clothing and gear carried or worn changes with him. The wearer can dismiss the cactus form as a free action.
