U have armor and weapon tickets that upgrade from 0 to +x for set amount of time (1day,7days etc). day before it expires u put in the bank and after it expires ur weapon/armor is unbinded (it has to be in the bank durring expiration)..Those tickets u can get from 50-55 chests,i think u can also buy from AH.
i have a question about the ticket bug; i have gloves +10 and ticket +6. can i use the ticket on the gloves that have higher upgrade so it remove the bind after 1 day? if yes what will happen? will i have gloves +10 again?
