hello!!
You all know about the old mailbox exploit that did allow you to enchant shoulder with Aldor enchant / Scyer enchant, or Cenarion Expedition head enchant. That exploit did blizzard fix ages ago.
Now there is a new way!!!!!
Same way as with the mailbox but instead use you guild bank.
1. Get the enchant you want, and the head and shoulder you want it on. (Get a lot of it cause its hard to make the timing perfect).
2. Then go to the Guild bank. (Both you lvl 70/friend, and twink most be in same guild and have access to guild bank).
3. Open your bags with the lvl 70.
4. Start cast the enchant at the item. (Accept that the item will be soul bound to you).
5. Open guild bank.
6. When the casting bar reach 99%, move the item to guild bank.
7. Log you twink and take the item out of guild bank.
Its better to Move the item to early to guild bank then to late, if you move it to early u will cancel the spell. If u move it to late you will waste your regents.
The cast bar shall be like this [===================X] (where the X are).
here is a list of all head and shoulder enchants!
