Lua Help with spell

[Equalizer]

Yo all,

Can someone help me with this spell?

I am having a great spell script but I need to change something, but I am not able to do it myself.

This is the spell:

local arr = {}
 
arr[1] = { 
{0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0}, 
{0, 0, 0, 1, 1, 1, 1, 1, 0, 0, 0}, 
{0, 0, 1, 1, 1, 1, 1, 1, 1, 0, 0}, 
{0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0}, 
{0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0}, 
{1, 1, 1, 1, 1, 3, 1, 1, 1, 1, 1}, 
{0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0}, 
{0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0}, 
{0, 0, 1, 1, 1, 1, 1, 1, 1, 0, 0}, 
{0, 0, 0, 1, 1, 1, 1, 1, 0, 0, 0}, 
{0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0}, 
} 
 
arr[2] = {
	{0, 0, 0, 0, 1, 0, 0, 0, 0},
	{0, 0, 0, 1, 0, 1, 0, 0, 0},
	{0, 0, 1, 0, 0, 0, 1, 0, 0},
	{0, 1, 0, 0, 0, 0, 0, 1, 0},
	{1, 0, 0, 0, 2, 0, 0, 0, 1},
	{0, 1, 0, 0, 0, 0, 0, 1, 0},
	{0, 0, 1, 0, 0, 0, 1, 0, 0},
	{0, 0, 0, 1, 0, 1, 0, 0, 0},
	{0, 0, 0, 0, 1, 0, 0, 0, 0}
}
 
arr[3] = {
	{0, 0, 0, 1, 0, 0, 0},
	{0, 0, 1, 0, 1, 0, 0},
	{0, 1, 0, 0, 0, 1, 0},
	{1, 0, 0, 2, 0, 0, 1},
	{0, 1, 0, 0, 0, 1, 0},
	{0, 0, 1, 0, 1, 0, 0},
	{0, 0, 0, 1, 0, 0, 0}
}
 
arr[4] = {
	{0, 0, 1, 0, 0},
	{0, 1, 0, 1, 0},
	{1, 0, 2, 0, 1},
	{0, 1, 0, 1, 0},
	{0, 0, 1, 0, 0}
}
 
arr[5] = {
	{0, 1, 0},
	{1, 2, 1},
	{0, 1, 0}
}
 
arr[6] = {
	{0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0},
	{0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0},
	{0, 0, 0, 1, 1, 1, 1, 1, 0, 0, 0},
	{0, 0, 1, 1, 1, 1, 1, 1, 1, 0, 0},
	{0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0},
	{1, 1, 1, 1, 1, 3, 1, 1, 1, 1, 1},
	{0, 1, 1, 1, 1, 1, 1, 1, 1, 1, 0},
	{0, 0, 1, 1, 1, 1, 1, 1, 1, 0, 0},
	{0, 0, 0, 1, 1, 1, 1, 1, 0, 0, 0},
	{0, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0},
	{0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0}
}
 
local formulas = {
	[6] = {COMBAT_FORMULA_LEVELMAGIC, -11.0, -1900, -10.2, -2000}
}
 
local function onTileComb(cid, pos)
	if(isCreature(cid) == TRUE) then
		doSendDistanceShoot(pos, getThingPos(cid), 3)
	end
end
 
local combats = {}
for i, v in pairs(arr) do
	combats[i] = createCombatObject()
	setCombatParam(combats[i], COMBAT_PARAM_TYPE, COMBAT_FIREDAMAGE)
	if(i < #arr) then
		_G["callback" .. i] = onTileComb --Mwahaha
		setCombatCallback(combats[i], CALLBACK_PARAM_TARGETTILE, "callback" .. i)
	else
		setCombatParam(combats[i], COMBAT_PARAM_EFFECT, 6)
	end
 
	if(formulas[i] ~= nil) then
		setCombatFormula(combats[i], unpack(formulas[i]))
	end
 
	setCombatArea(combats[i], createCombatArea(v))
end
 
local isCharging = {}
local function eventFunc(p)
	local cid = p.cid
	local n = p.n or 1
 
	if(isCreature(cid) == FALSE) then
		isCharging[cid] = false
		return LUA_ERROR
	end
 
	if(isCharging[cid] and n == 1) then
		if(isPlayer(cid) == TRUE) then
			doPlayerSendCancel(cid, "You are already charging it.")
		end
		return LUA_ERROR
	end
 
	isCharging[cid] = (n < #combats)
 
	local pos = getThingPos(cid)
	if(getTilePzInfo(pos) ~= FALSE) then
		isCharging[cid] = false
		return LUA_ERROR
	end
 
	local var = positionToVariant(pos)
	if(doCombat(cid, combats[n], var) == LUA_ERROR) then
		isCharging[cid] = false
		return LUA_ERROR
	end
 
	if(isCharging[cid]) then
		addEvent(eventFunc, 500-n*100, {cid=cid, n=n+1})
	end
	return LUA_NO_ERROR
end
 
function onCastSpell(cid, var)
	return eventFunc({cid=cid})
end

My problem is; the combat formula is now

{COMBAT_FORMULA_LEVELMAGIC, -11.0, -1900, -10.2, -2000}

But I want to change it to a formula like;

function onGetFormulaValues(cid, level, maglevel)
	min = -(1200 + maglevel * 10)
	max = -(1200 + maglevel * 15)

	return min, max
end

setCombatCallback(combat, CALLBACK_PARAM_LEVELMAGICVALUE, "onGetFormulaValues")

But when I replace it, the script doesn't work.

Please help me rep+
