[Derision]

You want to check the sanity of the rule setting, to stop a crash when accessing the array if someone sets it to an invalid value:

// figure out if they should lose exp
	float GetNum [] = {0.005f,0.015f,0.025f,0.035f,0.045f,0.055f,0.065f,0.075f,0.085f,0.095f };
	int Num = RuleI(Character, DeathExpLossMultiplier);
	if((Num < 0) || (Num > 9))
		Num = 0;
	float loss = GetNum[Num];
	exploss=(int)((float)GetEXP() * (loss)); //Angelox: lose % of total XP pending rule (choose 0-9)

I would also change GetNum & Num to more meaningful names.
