[Hinataa]

Well i bought it first day of expansion..... n i think its not working... while my friends who have same lix get 800-900 xp per wt4 run, i get 500xp like ppl get without lix...

Yours must have expired, look at the expiration on the sticker on the bottom of the bottle =]

The people who et 800xp stack like 2-3 elixirs + abbaddon
