instant kill

Uhhh...no it doesn't, unless you hold down your bind for a good 10 secs and lag yourself out. Otherwise, it's the best way to kill.

Anyone know any good commands to level up faster?

Not unless you're an Evie.

Yeah, I would suggest just going along with quests as you get them. It saves time later down the road. I'm a stickler for a semi-decent story line, too. Vindictus doesn't have the best.. but it's a decent read ^^

i guees i my troll attempt was succesful

Only if the guy tried it lol

No I didnt try it, with me running things on max I stuck to 60
