You will now notice that the Combat Grounds have opened up, allowing you to take on about a dozen different enemies at the moment (more to come very soon). I would highly suggest bringing along some food, a weapon and some armor if you plan on spilling a lot of blood. Some enemies can be more a little more fierce than they appear to be.
Thank you all for being so patient with the release of combat, I know you've been looking forward to it the most (I have as well). I'm sure you'll enjoy what you see, so go give it a try! Let me know on the forums about any feedback you might have. Good luck and have fun!
