Yala quest

Hello brother
I've planned to make yala quest script and i will post it but i need simple code for this part
( Kill Tormented Ghosts and use the Ghost Residue on the charm thrice — this will make 6 more Tormented Ghosts appear. At this point the Ghost Charm will then change into a Charged Ghost Charm.)
i wanna code that use dead ghost on (x,y,z)
so any one can help
i will post it here when i finishing it free :D

Try thinking something with the code below

Code:

---

local pos = Self.Position()

for x = -7, 7 do
    for y = -5, 5 do
        if (Map.GetTopUseItem(pos.x + x,pos.y + y, pos.z).id == <dead ghost id here>) then
            return {x = pos.x+x, y = pos.y+y, z = pos.z}
        end
    end
end
