Potion of Drunk Muscles

Adventuring Gear Common

When you drink this potion and are poisoned, you gain a +2 bonus to your Strength score to a maximum of 20. This increase lasts for 1 hour or until the poisoned condition ends, whichever comes first. When the effect wears off, you gain one level of exhaustion. This potion is a pure yellow liquid that tastes like raw eggs.
