Q:
Boost Enchantment Powder does not seem 2 work
A:
There are several different items named “Experience Booster” with different effects. The boost enchantment powder only works on the (discontinued) blue (fine rarity) ones that give 50% experience from kills for one hour and nothing else. The green (masterwork) and yellow (rare) Experience Boosters, which give 50% experience in all game types, PvP reward track gain and kill streaks for 30 minutes or 2 hours can not be used with boost enchantment powder.
