could somebody please help me to script monster which will decrease experience on each sucesfull hit ? I think some onHit or onDealdamage hook for monster attack and regular gain exp with minus sign for damaged champion should work ?

Example monster definition: Script Object: (name it drainExp) https://www.dropbox.com/s/84cn0jgyylkhb ... h.avi?dl=0

		if level < 20 then
		   return XPtable[level]
		else
		   return level * 1000000

	end

    function _adjustIfHuman(champion, amount)
		   if champion:hasTrait("human") then
			  amount = amount * 0.91
		   end
		   return amount

    function loseExp(champion, amount)
       amount = _adjustIfHuman(champion, amount)
       local currentLevel = champion:getLevel()
       local currentExp = champion:getExp()
       local minimum = _minimumXP(currentLevel)
       if currentExp > minimum then
             if currentExp + amount >= minimum then
                champion:gainExp(amount)
                return true
             else
                champion:gainExp((currentExp - minimum)*-1)   
                champion:gainExp(_adjustIfHuman(champion, (minimum - champion:getExp())))   
                return true
