I was trying to do an Exploit that I know to overenchant but in the C3+C4 dont work, when i was trying i discovered the new one.
To enchant without use scroll is simple:
First get the item what u want enchant and 1 scroll of enchant of the same grade, set up a shop (/vendor) then sell the scroll for 1adena, call a friend to buy it of you talk to him only drag it to buy but dont click "OK", then count down to 3 and when ur friend click "OK" u click in the item with the scroll, it appear No such scroll to enchant, look ur friend is with the scroll but ur weapon dont enchanted, then trade with him again and get back the scroll, now the trick put the weapon in ur gear.... WOW u have enchanted ur item now..
Sry my english, cuz Im br.
If u understood me u ill do it correct.
