Crafted from blueberries, resin, Graydwarf eyes, and a Troll skin (or perhaps more rare ingredients?) Woad works like a potion, with visual changes to the wearer's body while they're using it. Character model shows vivid, faintly glowing blue markings.
When woad is applied and takes effect, the wearer's stamina, damage, and movement speed are drastically increased. Body paint does not affect their health recovery or ability to handle the elements. Woad lasts for 1 minute before the body paint is worn off, then has a 20 minute cooldown before it can be applied again. Player must remain in motion, or damage enemies, for the Woad to continue working. Wearer must not have any clothing or armor equipped (woad is treated like clothing for the duration perhaps?). Re-equipping armor / clothing negates woad and the body paint cannot be re-applied after the cooldown.
