The Orb of Deception is one rare and cool transformation trinket.
When you use the trinket it transforms you to look like a member of the opposing faction for 5 minutes.
It has a 30 minute cooldown.
Below is a list of the race changes:
Blood Elf <-> Draenei
Goblin <-> Worgen
Forsaken <-> Night Elf
Orc <-> Human
Tauren <-> Gnome
Troll <-> Dwarf
It has a low drop rate from a number of different mobs and bosses. See a complete list at Wowhead.
You must be level 54 to use the trinket.
I love being a Blood Elf, but female Draenei’s are also gorgeous. I love walking around looking like the gorgeous Draenei I transform into above when I use the Orb of Deception.
