The Berserker Potion is a potion added by the Nether Expansion idea pack. It cannot be brewed, however, and is only obtained with a 30% drop rate from the Demon Berserker, a very dangerous mob found in the cells of Demon Castles. By default, the effect lasts for 3 minutes.
When the Berserker Potion is drunk, the player drinking it will get Strength III but also get Resistance -II. This makes them much more susceptible to melee attacks, but also hit much harder. Even a punch can hurt.
Like most potions, the Berserker Potion can be affected by these modifiers when brewing:
- Glowstone Dust: Makes it more potent (Strength IV and Resistance -III)
- Redstone: Lengthens the effect duration from 3 minutes to 8.
- Gunpowder: Turns it into a splash potion. Takes 2 minutes off the effect duration.
