This game is funny. After lv up, I fight with a creature lv 3 and I die. After that I got lv 1 again. And is it good that I take rage in the beginning game? Sorry.
You lose exp from dieing. No rage isnt recommended. Its recommended to save all your skill points until 25 and get the learning skill. Put all your points into damage for your attributes. It will get easier as you get better gear.
