Mellowroot

Source Advanced Race Guide

Sneaky goblin chieftains give this orange paste to the tribe’s warriors before proposing a particularly bold raid. Consuming mellowroot causes a euphoric feeling that makes you feel invulnerable. For 1 hour after consuming mellowroot, you gain a +5 alchemical bonus versus fear effects. However, while under the effects of mellowroot, you must make a DC 15 Will saving throw when you try to leave the threatened area of an opponent. If you fail the saving throw, you cannot leave the threatened area with that action but do not lose the action.
