well, i don't know what did I do. I only noticed after that, when I already lost like 3k damage.

originally i had like 12k damage, then for some reasons, suddenly, i noticed my damage become 9k

then i noticed, i got few blues and even 1 rare item with strength only (i am a wizard btw).

I guess I just vendor few of my rares.....and they are not in the buyback list....
