Oil of Keen Edge

[Nator]

In Hero Lab, you can buy an Oil of Keen Edge for 750gp. The item description only says this, "Aura: Faint Transmutation, CL 5, Slot None, Cost 750GP, Catagory: Oil/Potion, Doubles normal weapon's threat range."

That's it, nothing more.

Now the Spell Keen Edge says that its duration is 10 min./level, which would be a minimum of 50 min. Is that how long the Oil lasts or is there a different duration for it?

[Cuup]

10 minutes per level at [CL 5] would indeed be 50 minutes.

[Claxon]

Yes, potions are usually always made at minimum caster level, and that would be the caster level you use to determine the effects, such as time.

So in this case an oil of keen edge would last 50 minutes.

Thank you both for confirming my thoughts!
