Wiesnbräu

The Wiesnbräu is a consumable buff potion that causes the player to take no damage, but also reduces the damage dealt, for 30 seconds. It behaves very much like ale, but also activates the Potion Sickness debuff, which doesn't 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".
