Not sure about how to do this.

Alright I have everything I need to powerlevel other players and since I need some cash I decided to give it a try. But when I killed all the mobs with my client standing 15 feet away they got 0 xp. Can anyone tell me what happened here? Do they need to attack, or get hit, or what? They got drops from the mobs but no xp so I just wondered. Please don't flame this thread with stupid comments about powerleveling.

aggro everything, then have em stand RIGHT next to you. they wont get atacked, but gt xp

also im just hoping you mean in-game cash here... hehe. but yeah, generally if you're close enough you get the exp, but if you're too far away you won't get exp. And to be honest, as long as you have a reusable res, it doesn't matter if they DO get hit.

I personally am sort of opposed to power leveling, but the bottom line is your client must "interact" in some way to receive XP. Here's a few ways for your client to receive XP: If they have R, W, or E in either their primary or secondary profession, have them pack a running skill(such as Sprint for W's, Dodge for R's, Windborn Speed for E's) and after you take the entire aggro, have them run right next to you, like suggested by Wrath, and then if need be they can make a quick runaway with that running skill.
But if they are Mo, N, or Me, have them cast some sort of enchantment or spell on you from a distance.(such as Mending for Mo's, Blood Ritual for N's, Inspired Hex for Me's). Another way for them to interact is once you have the aggro under control, have them cast some sort of offensive spell on an enemy you are fighting. That's just a few suggestions, but use your imagination as to how your clients should "interact."

Yes this is for ingame cash. And thank you Rayne for that idea. I could always use a mending on me and can't bring it myself because of negative energy regen.
