Script causes server to slow down?

The script works perfectly fine in studio but when I play the game, it crashes the moment I try to enter.

while true do wait(0.1) if script.Parent.Humanoid.Health == 0 then local maths = math.random(1, 1)
local tool = game.ReplicatedStorage.Rats:FindFirstChild("Poison") local nothing = game.ReplicatedStorage.Rats:FindFirstChild("Nothing")

if maths == 1 then
    local toolc = tool:Clone()
    toolc.Parent = game.Workspace
    toolc.Handle.CFrame = script.Parent.Head.CFrame + Vector3.new(5,2,0)
    script:remove()
else if maths == 2 then
    local nothingc = nothing:Clone()
    nothingc.Parent = game.Workspace
    nothingc.Handle.CFrame = script.Parent.Head.CFrame + Vector3.new(0,-200,0) 
    script:remove()
else if maths == 3 then
    local nothingc = nothing:Clone()
    nothingc.Parent = game.Workspace
    nothingc.Handle.CFrame = script.Parent.Head.CFrame + Vector3.new(0,-200,0)
    script:remove()
else if maths == 4 then
    local nothingc = nothing:Clone()
    nothingc.Parent = game.Workspace
    nothingc.Handle.CFrame = script.Parent.Head.CFrame + Vector3.new(0,-200,0)
    script:remove()
else if maths == 5 then
    local nothingc = nothing:Clone()
    nothingc.Parent = game.Workspace
    nothingc.Handle.CFrame = script.Parent.Head.CFrame + Vector3.new(0,-200,0)
    script:remove()
else if maths == 6 then
    local nothingc = nothing:Clone()
    nothingc.Parent = game.Workspace
    nothingc.Handle.CFrame = script.Parent.Head.CFrame + Vector3.new(0,-200,0)

wait(1) end end end end end end end end
