Lua Exori but healing if hit a monster or player

Hello, I was trying to do this by myself, but I couldn't think in a way to make this work
I want exactly like the title. Knight uses exori, if the spell hits a monster or a player, the knight get healed, if hits 2 monsters or players, heals 2 times the healing and so on.
Thank you
Exori's code

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
setCombatParam(combat, COMBAT_PARAM_USECHARGES, true)

local area = createCombatArea(AREA_SQUARE1X1)
setCombatArea(combat, area)

function onGetFormulaValues(cid, level, skill, attack, factor)
    local skillTotal, levelTotal = skill + attack, level / 5
    return -(skillTotal * 0.9 + levelTotal), -(skillTotal * 1.9 + levelTotal)
end

setCombatCallback(combat, CALLBACK_PARAM_SKILLVALUE, "onGetFormulaValues")



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

Spoiler

remove - from

return -(skillTotal * 0.9 + levelTotal), -(skillTotal * 1.9 + levelTotal)

so it is like that

return (skillTotal * 0.9 + levelTotal), (skillTotal * 1.9 + levelTotal)

oh, nvm - I missed that part

the knight get healed, if hits 2 monsters or players, heals 2 times the healing and so on

You need to iterate over the area of the spell, find affected creatures and for each of them heal cid for the values from onGetFormulaValues.
I cannot really write it, I don't have much experience with those outdated engines.
