A while back, I posted a little look at Morgion's bank, which was crammed full of various transmog pieces. It was pretty full! But since then, I replaced the 20-slot Frostweave Bags with 26-slot Illusionary Bags...and picked up even more transmog pieces.
Anyway, last week I learned of an AMAZING new addon called Goblinventory, created by the people behind The Undermine Journal. This addon produces a viewable webpage with a full list of your inventory, bank, guild bank and void storage contents, sorted and everything. You can also exclude certain items you don't want to show up in the total, like your Hearthstone, buff foods, Grisly Trophies or whatever you want.
You can link it to friends, or just use it for your own reference to know what exactly you've got stashed away. For example, here's a quick page I threw together showing the contents of my storage guild banks on Drenden. (Narci, here is where you have a field day telling me about all the useless crap I should get rid of.)
To anyone who tends to hoard stuff like me, I HIGHLY recommend it.
The only drawback I can see so far - and it's a minor one - is that it doesn't include your currently-equipped items in the tally. However, you can get around this by unequipping all your gear and simply having it all in your bags. Or, if you don't have the bag space for that (who does??) you can export your data, equip a different set, then export the data again (the site lets you combine multiple data exports). You then have to unselect all the duplicate items, which does take a few minutes, but the end result is a full inventory list.
So what did Morgion's bags end up looking like? Well, here's the export page for Morgion - a full list of her equipped items, bags, bank slots and void storage slots. (Ignore the empty slots in the first section - that's a result of 'tricking' the addon into including your equipped items.)
It's, uh...it's a lot. Look at what you have done to me, transmog. Just look.
Here's a few totals that caught my eye:
19 1-hand axes
25 1-hand swords
36 chests (including one plate dress “robe”)
I don't know how I'm going to handle a whole new expansion with dozens of new transmog pieces. I really don't.
