Guild Wars 2

What does gthis do? I don’t get it…
Does it add a 11th utility skill slot?

-_- I hope not… I play on the xbox360 controller with all skills mapped perfectly already.

The exact same thing as the metabolic primer, but for oils/potions instead of food.

No, it makes utility consumables (like potions) last a lot longer when it is active. It works exactly like the metabolic primer gem item does for foods.

It means 12 hour sharpenning stone buffs.
