Can someone explain why my Linked sword kill effect isn't working?

So I've been trying to make kill effects for my game, but it seems the vanish kill effect is bugged. I have the script in a local script under the tool name "Forcefield" which is the name of the weapon.

When I test and kill someone the kill anchors, but other than that it doesn't seem to work.

Here's the script:

local Players = game:GetService('Players')
local toolName = 'Forcefield'

Players.PlayerAdded:Connect(function(Player)
    Player.CharacterAdded:Connect(function(Character)
        local Humanoid = Character:WaitForChild('Humanoid')
        Humanoid.Died:Connect(function()
            if Character:FindFirstChild(toolName) or Player.Backpack:FindFirstChild(toolName) then

                for i, v in pairs(workspace:WaitForChild(script.Parent.Name):GetChildren())do
                    if v:IsA("Accessory") then
                        v.Handle.Anchored = true
                    elseif v:IsA("MeshPart") then
                        v.Anchored = true
                    elseif v:IsA("UnionOperation") then
                        v.Anchored = true
                    elseif v:IsA("Part") then
                        v.Anchored = true
                    end
                end
                for i = 1,20 do
                    wait(0.0025)
                    for i, v in pairs(workspace:WaitForChild(script.Parent.Name):GetChildren())do
                        if v:IsA("Accessory") then
                            v.Handle.Transparency = v.Handle.Transparency + 0.05
                        elseif v.Name == "Head" then
                            v.Transparency = v.Transparency + 0.05
                            v.face.Transparency = v.face.Transparency + 0.05
                        elseif v:IsA("MeshPart") then
                            v.Transparency = v.Transparency + 0.05
                        elseif v:IsA("UnionOperation") then
                            v.Transparency = v.Transparency + 0.05
                        elseif v:IsA("Part") then
                            v.Transparency = v.Transparency + 0.05
                        end
                    end
                end
            end
        end) 
    end) 
end) 

Can anyone explain what I have done wrong so I know what to keep in mind in the future? Please and thank you.
