Retards, yes?
1. this is a display bug, the stats listed there are not the real stats - if you want the real stats, you can look either on the heirloom list under the 'retirement' tab on c-rpg.net, or you can look at it in-game (in-game stats are correct).
"But i'm a retard, so i can't see it ingame, QQ!"
2. if you can't see it in-game, go to the equipment tab on c-rpg.net, put the bec (The bugged, tempered bec) in one of your default equipment slots, that will make it appear in-game with the correct stats and all.
