I'm getting half of the bonus xp

Dekundo

I'm getting 5 % for being in a group of two and getting 25 % from Psijic Ambrosia.
Example : from a dungeon run without Psijic Ambrosia I'm getting 52k xp and using it I'm getting 65k xp

Experience bonuses are additive, not multiplicative. If you wear gear with the training trait, or have other experience bonuses, the potion will not increase your total xp by 25%.
