[provocating]

My source will differ from yours, modified it some. But in your attack.cpp you will have a routine

bool Client::Attack(Mob* other, int Hand, bool bRiposte, bool IsStrikethrough, bool IsFromSpell, ExtraAttackOptions *opts)

Look somewhere around line 1500~1600 and you will see this.

	if(!GetGM())
	{
		if(exploss > 0) {
			int32 newexp = GetEXP();

			if(exploss > newexp) {
				//lost more than we have... wtf..
				newexp = 1;
			} else {
				newexp -= exploss;
			}

			SetEXP(newexp, GetAAXP());
			//m_epp.perAA = 0;	//reset to no AA exp on death.
		}

I would think you could change the one line to read something like this.

SetEXP(0,0);
