BUT Blizzard DID give us The Emperor's New Cape which drops off of Emperor Dagran Thaurissan in Blackrock Depths. THIS they make moggable when we already have the option to hide our cloaks. CRAZY!
There ARE some useful invisible items out there! Are you a Death Knight? If so, you're in luck! The Archerus Knight's Girdle you get from the starter zone is invisible!
Did you miss out on Griftah's Authentic Troll Shoes during the Barrens Invasion event? If you're a Tauren, Troll or Draenei these will be invisible:
- Mail wearers: Tsunami Boots
- Plate wearers: Ancient Skeletal Boots / Boots of the Funeral March / Foreshadow Steps / (Paladin only) Crafted Dreadful Gladiator's Greaves of Meditation & Alacrity
- Cloth wearers: There are SO MANY that I can't list them all. I'm mostly a Draenei-person, so I take all my ladies out to Azuremyst for the Kurkenstoks and don't keep any other "invisible" ones.
- Leather wearers: Ravenholdt Boots
Are you out of bank space? If you dual wield, you don't need to get both fist weapons - you can use the same weapon to mog both hands!
Do you have a soulbound item that you don't use much? Check on WowHead to see if it has a look-a-like BOE version. Buy it at the AH or farm it and send it to an alt bank for storage until you want to wear it again. Delete the soulbound one.
There are also some fun/unique items for transmog. Have an alchemist? Mog the offhand with a Vial of Chloroform if you haven't already done the Alliance Redridge quest that rewards it. Even better, mog a beaker of Tears of Heaven which is a vendor item you don't have to farm or quest for!
There are Picks, Shovels, cricket cages, lanterns and even pots of boiled squirrels! There are multiple versions of these items, so just click on the "same model as" tab on wowhead to search for other versions that might be easier to get.
Engineers have many options for goggles, but I think my favorite is still the Gnomish Mind Control Cap - I just wish that some of the hats wouldn't make our hair disappear :P
There's a similar cloth cap found in (dare I say it?!?) GNOMEREGAN: Electromagnetic Gigaflux Reactivator.
Do you use unique or fun items in your transmog? I'd love to see pictures!
