local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_MANADRAIN)
setCombatParam(combat, COMBAT_PARAM_EFFECT, 30)
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, 255)
setCombatFormula(combat, COMBAT_FORMULA_LEVELSKILL, -4.8, -60, -4.4, -90)

local distanceCombat = createCombatObject()
setCombatParam(distanceCombat, COMBAT_PARAM_TYPE, COMBAT_MANADRAIN)
setCombatParam(distanceCombat, COMBAT_PARAM_EFFECT, 30)
setCombatParam(distanceCombat, COMBAT_PARAM_DISTANCEEFFECT, 255)
setCombatFormula(distanceCombat, COMBAT_FORMULA_LEVELSKILL, -4.8, -60, -4.4, -90)

function onCastSpell(cid, var)
	if(variantToNumber(var) ~= 0) then
		return doCombat(cid, distanceCombat, var)
	end
