Forum:Old heroes from oracle

i went to the link to buy old heroes/items from the oracle and typed it in correctly and made sure i had enough favor pts (have 26 and was trying to buy barbarus' helm for 25). when i entered the link correctly it said wrong reward and would not let me get his helm. is it because the item is out of stock or am i too high of a lvl (lvl 178)? once i get enough favor pts i also want to buy kaiser so i want to know if this will be a recurring theme or just a minor issue right now. thankyou
