Question about function in xml

[Gothric]

i want to add absorb percent dead in addon bonus system in outfits.xml but i dont know what function use to fix it

 <outfit id="1">
		<list gender="0" lookType="136" name="Citizen">
				<stats maxHealth="50"/>
				<stats precentDeath="50"/>
	</list>
		<list gender="1" lookType="128" name="Citizen">
				<stats maxHealth="50"/>
                               <stats precentDeath="50"/>
	</list>

i think that it will work only for full addon , but i want to absorb 5% of death dmg if player has only first addon, and maybe 10% when he has second addon :|

so can anyone help me? i think thats impossible to do it in lua
