XP Potion
An XP potion increases the XP gains from active or passive activity. They are potions made with the alchemist profession. They are limited to one Episode area each with a different recipe for each area. Increasing variants provide a stronger XP boost percent.
Normal XP potions increase active XP gained for 2 minutes. Some examples are the 5% Potion XP Hopeport and 5% Potion XP Hopeforest.
Passive potions last one hour (60 minutes), but only affect passive training. One example is the 5% Potion XP Hopeforest (passive).
Bear in mind that the XP potion takes up a space in the inventory, but they will stack.
