That's a the beauty of exploration. Mobs in this game have levels. Orcs are level 6 I think, so it's normal that you can't kill them at level 1. So you basically have to make your wait into town and start doing little questing here and there. Then eventually you'll egret to mobs of your levels. It's not perfect but right now in beta map there are mobs of level 4,6,8. So you have to be either well equipped with skills weapons or wait until you level up. Do a lot of exploration, see which mobs are which level before you attack. Open barrels and chests.

The tutorial cave is pretty much just to show you how to move, how to open secret doors and how to loot. They are working to make tutorial better. So in about a month we may have a better Beta me thinks. Remember it is a Beta, which means that game is in bug-fixing and polishing stage right now. So be constructive and submit constructive feedback wink.
