When you drink this potion, you become fleeing for 1 minute, and you gain a +40-foot status bonus to all your Speeds for the duration as long as you are fleeing.
You're forced to run away due to fear or some other compulsion. On your turn, you must spend each of your actions trying to escape the source of the fleeing condition as expediently as possible (such as by using move actions to flee, or opening doors barring your escape). The source is usually the effect or caster that gave you the condition, though some effects might define something else as the source. You can't Delay or Ready while fleeing.
The fleeing condition is usually negative, it takes you out of the encounter. But the Potion is the effect, so in which direction are you supposed to be running?
