Correct, I've not implemented something like this yet, as I have not thought of a suitable system for my mud. :)

Say you're a healer and you don't do any damage at all during the fight, but you keep the tank alive by healing them throughout the battle. You didn't do damage, but you definitely were part of the fighting, but with this system as it is you would get no experience. Also should other things like debuffing spells be taken into account? Like if you dispel the mobs sanctuary or lower it's AC with faerie fire. Things like that can turn the tide of the battle yet with this system as is would get no exp. I'm not saying the system as written is bad, I like what's been done and I've always planned on doing something similar. I just think to make the whole system fair you need to account for all functions of the battle. You could probably even do this, with the system Jason already wrote just consider healing a person within the group doing damage against the mob and make different debuff spells equivelent to a certain % of damage done also. You'd have to somehow subtract a % of the damage from the people doing direct damage so that it balanced out, but it's doable. Just my 2 cents, Jason --- Jason Gauthier <[EMAIL PROTECTED]> wrote: >(Not a hold hand snippet, but all the code required to do this) > >Two big reasons for doing this include: > >No more kill stealing >No more power leveling > >You get out of a fight what you put into it. > >In doing this, I also changed how experience works. >No longer, is experience based on difference of levels, it's now based on >level of the mob. >For instance, a level 100 mob will give 500 experience regardless of players >level.
