Okay, for those who didn’t follow the thing before the mods/GMs deleted posts made on the forum topic, this “hack” is not duping.
He only exploited a little tiny defect on the Jone’s Blessings page. He replaced the ID of the Jone’s Blessing by the ID of Love:Up and Down and he got genuine unique-ID’d tome. It’s a pretty easy thing to do and I bang my head against the wall for not having thought of it before
To perform it, you only had to right click on the item you wanted to get (normally Jone’s Blessing or the other one) and you’d hit “inspect element”. You’d then find yourself in front of some internet language and by navigating a little you’d have found the line “itemid” and next to it “value=28297”. Then he just double clicked on the value, changed it to the ID of LU&D and there ! The GMs basically sent him a genuine LU&D tome !
It’s official though, the bug has been fixed and you can’t stop dreaming about sending yourself GM weapons or such !
The “hacker” got perma ban on all the PWE games.
