Programmer [Paid Job] New spell functionality

[poe6man3]

Im looking to create new functionality.
Here is the video with example:

Another one:

Additional info:
When spell is used/or called with a function inside spell the player is shown the area of the spell and is able to choose position where the spells damage/effect is dealth/shown
If player goes further then the area range the sprite of a spell area is changed into red color

Spell example:

local animation = {
    cast = {
        start = 29,
        stop = 33
    },
    loopFirst = {
        start = 34,
        stop = 37
    },
    loopSecond = {
        start = 38,
        stop = 41
    },
    attack = {
        start = 42,
        stop = 50
    },
    fail = {
        start = 51,
        stop = 55
    }
}

local function loopAnimation(creature, lookType)
    if not creature or creature:isRemoved() then return end
   
    creature:setOutfit({lookType = lookType})

    if lookType == animation.loopFirst.stop then
        addEvent(loopAnimation, 100, creature, animation.loopSecond.start)
    elseif lookType == animation.loopSecond.stop then
        addEvent(loopAnimation, 100, creature, animation.loopFirst.start)
    else
        addEvent(loopAnimation, 100, creature, lookType + 1)
    end
end

local function castAnimation(creature, lookType)
    if not creature or creature:isRemoved() then return end
   
    creature:setOutfit({lookType = lookType})

    if lookType == animation.cast.stop then
        addEvent(loopAnimation, 100, creature, animation.loopFirst.start)
        AND THERE I WANT TO SHOW THE PLAYER THE AREA AND LET HIM CHOOSE THE POSITION WHERE TO THROW THE SPELL <--------------------------
    else
        addEvent(castAnimation, 100, creature, lookType + 1)
    end
end


local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_ENERGYDAMAGE)
combat:setParameter(COMBAT_PARAM_AGGRESSIVE, true)


local spell = Spell(SPELL_INSTANT)

function spell.onCastSpell(creature, variant)

    addEvent(castAnimation, 100, creature, animation.cast.start)
end

spell:name("genki dama")
spell:words("genki dama")
spell:group("attack")
spell:id(10)
spell:level(20)
spell:magiclevel(5)
spell:cooldown(10000) -- milliseconds, 10 seconds
spell:needTarget(false)
spell:isAggressive(true)
spell:allowFarUse(false)
spell:vocation("goku")
spell:register()

That's probably handled entirely by the client, spell script won't matter.
