How would i clone an object and put it in workspace??

I'm trying to understand what you're doing, but front what I can read you're trying to get a model from lighting, clone it and parent it to workspace. Then making that model be in the same position the character is when the character dies.

Assuming that I can actually go about fixing this.

--//Putting "local" in front of variables only used in the scope that it's in is good practice

local Character = script.Parent
local Dead = game.Lighting.Dead:Clone() --//Getting our Dead model. I'm calling clone here because just in case anything happens to the model inside of lightning, we'll always have a copy.
local Humanoid = Character.Humanoid

function OnDeath()
    local rootPosition = Character:GetPrimaryPartCFrame() --//Getting the CFrame of the root of the character
    local deadClone = Dead:Clone() --//Cloning our Dead model from lighting

    wait(0.5)

    deadClone:SetPrimaryPartCFrame(rootPosition) --//I'm assuming that it has a primarypart in it because it has a HumanoidRootPart inside of it.
    deadClone.Parent = game.Workspace 
end

Humanoid.Died:connect(OnDeath)

I describe most of what I'm doing in the scripts comments, but I'm basically just doing what I said above.
