Psychic Raiments

You draw ectoplasm from the Astral Plane to encase your body in a protective layer. After it initially forms you can, as a free action, make the material take the shape and appearance of any non-magical clothing or armor you wish, and may do so as often as you like for the duration. This is not an Illusion and will hold up to physical inspection, however if a portion of it is cut away or separated, the removed portion will revert to a silvery gel and dissolve back into the ether within 1 round. The spell ends if you don armor or dismiss the spell as an action. 

While wearing Psychic Raiments your base AC becomes 12 + your Charisma modifier and as an action you can cause the Psychic Raiments to grow claws over your fingers allowing you to make a melee spell attack which deals 1d8 Psychic damage.
