Wiesnbräu

The Wiesnbräu is a consumable buff potion that grants the Immune buff when consumed. Under the effects of the buff, the player will take less damage, but also deal less damage (-50% damage, rounded up) for 30 seconds. Consuming it also activates the Potion Sickness debuff, and it cannot be used while the debuff is active. It is purchased from the Merchant for, during Oktoberfest.
