Guild Wars 2

For potions such as this one:

Weak Potion of Ogre Slaying
Nourishment(30 m): +3% damage vs. ogres
+10 Experience from kills
http://wiki.guildwars2.com/wiki/Weak_Potion_of_Ogre_Slaying

A) Is that +10 experience from killing ALL enemies, or just Ogres?

B) Can this stack with the +10 XP from food to give a cumulative +20?

It works for all enemies. There’s two types of consumables that can be active at the same time. One has apple icon and the other has wrench icon. Wiki isn’t very clear in making this distinction.

ooh that’s good to know. that there’s a diff between the wrench and apple. i know that if you eat another apple icon (usually food) then it disappears.

so technically, those effects CAN stack? if different types.
