First of all, this guide will only work for Monks, as we will be abusing the spell [Zen Pilgrimage].
What you want to do is use your [Zen Pilgrimage] spell somewhere before accepting a summon or hearthstoning, then use [Zen Pilgrimage: Return] to return to the place where you first used it. For example, if you're questing in Zangamarsh, but need to go to Orgrimmar to buy a glyph from the AH, you would use your [Zen Pilgrimage] spell, hearthstone, buy the glyph from the AH and then use the spell again to instantly teleport back to where you were. I'm sure this can be abused in many more ways, which I'll leave to the OwnedCore community to figure out
tl;dr
1. Use [Zen Pilgrimage]
2. Accept summon/Hearthstone
3. Use [Zen Pilgrimage: Return] days later for a free port to where you set it.![]()
