Battle-Bot, I choose you!
A Battle-Bot joined all my characters’ inventory a few days ago. He’s a neat little bugger.
The Battle-Bot was a clever ploy by Blizzard to get many folks to do the WoW Battle.net account merger. If you have not grabbed a bot for your account yet, MMO has a good article explaining the process. It’s really a painless procedure that takes about 5minuites to complete.
After the initial day of receiving the pet, you can get a stack of 5xBlue Battle Fuel or 5xRed Battle Fuel each following day by following the same link & logging in.
