As we all know, the Glyph of Felguard is going to add such a nice little transmog touch to our favorite demon. But, while you can go and run dungeons for drops, there's a few unique weapons that come from quests that you won't be able to get in Mists of Pandaria. The quest reward system where you only get what's right for your spec was applied retroactively to all the quests in the game. So there will be some really awesome items, such as Torn-Heart Axe of Battle
and Sword of Nefarian's Hand
won't be available once the patch comes out to begin Mists of Pandaria.
So, I made a small list of weapons you can only get from quests, that are relatively unique looking or unique colors. Also note, you can use common items for the Felguard. I'll post the item name, the name of the quest you get it from, or the first quest in the chain, and then the zone it's located.
Make sure to get your awesome weapons now before it's too late!
Oh, and feel free to respond with other items from quests that would be cool.
