Wiesnbräu

The Wiesnbräu is a consumable buff potion that causes the player to take reduced damage, but also reduces the damage dealt, for 30 seconds. Consuming it also activates the Potion Sickness debuff, and it cannot be used while the debuff is active. The duration of Potion Sickness does not start counting down until the effects of the brew wear off, effectively adding 30 seconds to the regular potion sickness debuff. The Wiesnbräu is purchased from the Merchant during Oktoberfest.

Trivia

 * It is the only consumable to cause the Potion Sickness debuff without restoring any health.
 * Wiesnbräu is depicted as being served in a bierstiefel, a common boot-shaped German mug for serving beer.
 * Beer served during Oktoberfest is better known in reality as Wiesnbier, which roughly translates to "festival beer".
