Lua Rod that heals per swing

[ziggy46802]

So far I got to this

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_BLOCKARMOR, 1)
setCombatParam(combat, COMBAT_PARAM_BLOCKSHIELD, 1)
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_EXPLOSIONAREA)
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_EXPLOSION)

setConditionFormula(combat, -0, -1, -2, -10)

setCombatCallback(combat, CALLBACK_PARAM_LEVELMAGICVALUE, "onGetFormulaValues")
 
 
function onCastSpell(cid, var)	
	return doCombat(cid, combat, var)

	return doCombat(cid, combat, var)
end

You see I got the main things for it to attack, but I didn't know if I had to go through special route of reaching the combat formula since is heals and damages. I wasn't sure how to call back the formulas so some help on that would be nice, but I do wan the 2 minimms for healing to be 0 and 1 and maximums to be 2 and 10, if that works ot.

Any help on this rod would be greatly appreciated and I will add in some surprising and random features to it and release it as well.

EDIT- No one wants rep? Even if you give me a non working script, as long as its me closer I'll rep you

Here is a script that almost works

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_BLOCKARMOR, 1)
setCombatParam(combat, COMBAT_PARAM_BLOCKSHIELD, 1)
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_EXPLOSIONAREA)
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_EXPLOSION)

function onGetFormulaValuesOne(cid, level, maglevel)
	local min = -1
	local max = -10
	return -min, -max
end

function onGetFormulaValuesTwo(cid, level, maglevel)
	local min = 1
	local max = 2
	return -min, -max
end
 
setCombatCallback(combat, CALLBACK_PARAM_LEVELMAGICVALUE, "onGetFormulaValuesOne")
 
 
setCombatCallback(combat, CALLBACK_PARAM_LEVELMAGICVALUE, "onGetFormulaValuesTwo")
 
	return doCombat(cid, combat, var)
end

The problem with it is that it heals the monster instead of the player, so how do I change it to the player?
