Porcupine Elixir

The liquid in this vial is dark brown, shot through with vertical threads of white and tan.

Imbibing porcupine elixir toughens your skin, granting you a +1 enhancement bonus to your existing natural armor bonus. (A creature without natural armor has an effective natural armor bonus of +0.) In addition, hundreds of needle-sharp quills sprout from your body. These quills enable you to deal 1d6 points of piercing damage with a successful grapple attack. The quills sprout through light armor or hide armor, but heavier armors prevent them from growing. The effect of this elixir lasts for 12 hours.
