Potion of Chameleon Skin

This potion changes colour constantly, shifting hue between all the known colours and a few only the elves can see. Once consumed the user can change the colour of their skin and held items to any hue they like, simply by concentrating. Whilst many outlandish adventurers use these potions simply as fashion items - changing their colour at a whim - they're most commonly used to aid in more sneaky pursuits. 

When used to aid in appropriate skill checks to hide or deceive, Potions of Chameleon Skin give a +5 bonus. The duration the effect lasts for depends on tier.
