Rage Potion

The Rage Potion is a vile concoction brewed by Alchemists, from various unsavoury animal parts. It is a thick bright red mixture, and when drunk causes violent mood swings and a marked increase of aggression in the drinker. For most people this just causes trouble, but warriors find this heightened state of anger of great use in their work.
