Alright on some private servers it doesn't allow you to equip items such as "Dragonmaw" Thottbot World of Warcraft: Dragonmaw and "Fireguard" Thottbot World of Warcraft: Fireguard at the same time. Well with a tiny glitch you can dw both! Here it goes. Note: only works on servers with a "master smith" trainer. Or any easy way to learn master sword/mace/axe ect.
Step 1: Get your "Master SwordSmith/Axe/Mace Smith" weapons that you want to dw.
Step 2: Learn "Master Mace/sword/axe Smith" from the trainer and equip the matching weapon (ex: "Dragonmaw" = Master Macesmith)
Step 3: Now go to the same trainer that you learned your first Master profession from and learn another Master smith prof. Example: You learned Master Macesmith, now learn master swordsmith
Step 4: Once you have your second skill learned, then equip the appropriate weapon in the appropriate slot (I.e. Master Swordsmith = Firequard > in off-hand.)
Result/glitch:
Basically you now have two weapons that require a "Master Smith" training equipped at the same time. Here is a screenshots of the result. (tested on beyond_WoW)
(Ps. Please don't flame I know this is sort of common sense but, I'm just trying to contribute )
Master Sword and Mace Smith at the same time!
