[Spell] Spell Damage affected by variable stats? +Repping

[Guitar Freak]

Hello, Ive been inactive these past months due to lack of time but when I get the chance I try not to lose practice on this and now I have a problem that I just cant seem to be able to solve.

This is the spell script for a normal spell:

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_ENERGYDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLUE)
setAttackFormula(combat, COMBAT_FORMULA_LEVELMAGIC, x, x, x, x)

local area = createCombatArea(AREA_CIRCLE3X3)
setCombatArea(combat, area)

function onCastSpell(cid, var)
	return doCombat(cid, combat, var)
end

Now, in constant.lua we got this:

COMBAT_FORMULA_UNDEFINED = 0
COMBAT_FORMULA_LEVELMAGIC = 1
COMBAT_FORMULA_SKILL = 2
COMBAT_FORMULA_DAMAGE = 3

In my case, none of these work.

Lets say I have an extra stat on all my players lets call it "whatever stat" and it is defined by a Storage Value.

So I want to know how can I make it so the spell hits based on THAT stat and not the common level/maglvl/skill/etc.

If you still dont understand, this is pretty much it ideally:

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_ENERGYDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLUE)

local area = createCombatArea(AREA_CIRCLE3X3)
setCombatArea(combat, area)

function onCastSpell(cid, var)
doCreatureAddHealth(TARGET, -(getPlayerStorageValue(cid, whatever_stat_storage) * whatever_formula))
	return doCombat(cid, combat, var)
end

(this is ofc an example and it doesnt work this way)

So thats pretty much it, I have tried many things and I just cant understand how to do that TARGET part on a spell..

(It doesnt even have to be a spell if you know how to do it somehow else simulating it)

Ill be +repping helpful answers.
Thanks in advance.

Example of sudden death by storages;

local combat =  createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_DEATHDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MORTAREA)
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_SUDDENDEATH)

function onGetFormulaValues(cid, level, maglevel)
	local min = -getPlayerStorageValue(cid, 1337) * value
	local max = -getPlayerStorageValue(cid, 1337) * value
	return min, max
end

setCombatCallback(combat, CALLBACK_PARAM_LEVELMAGICVALUE, "onGetFormulaValues")

function onCastSpell(cid, var)
	return doCombat(cid, combat, var)
end
