A Castlewars brew is a potion exclusive to Castle Wars, where they are found on a table in the respawn room. It provides the boosts from a super combat potion, a ranging potion, stamina potion, super restore, and imbued heart at once.

Effects

The potion restores 20% of the player's run energy per dose, and offers a 70% reduction in run energy depletion for 2 minutes.

Melee boost

Stat boosts to Attack, Strength, and Defence are calculated with: $\lfloor SkillLevel\times \frac{15}{100}\rfloor +5$.
