Only works as Day of the dead.
Easy to do, rollbacks your cooldowns (transmute epic gemz etc.)
Step 1. Get Bread of the Dead - Item - World of Warcraft to your mail (Make friend put to ah, send from alt etc.)
Step 2. Buy anything from vendor, like 1 copper, just ANYTHING.
Step 3. Use the cooldown you need (transmute w/e)
Step 4. Pick up the mail (remember to stack them as 1 because they will be deleted 1 by 1 when you pick them)
Step 5. You will disconnect, log back in and you will be where you vendored something, cooldown resetted.
This used to work with every duration item before they nerfed it so you cant send duration items with mail, gl.
