My script wont work?

Ok so I made this skill script the skill works fine but for some reason it does damage to me when I use it so can someone take a look at it and help me? I wanted it to do damage to the other players.

Player = game.Players.LocalPlayer
Char = Player.Character
Torso = Char.Torso
Mouse = Player:GetMouse()

function Move(key)
    key = key:lower()
    if key == "z" then
        print ("z was pressed")
        game.Players.LocalPlayer.Character.Torso.Anchored = true
        for i = 1, 100, 3 do        
            Move = Instance.new("Part")
            Move.Parent = Workspace
            Move.Size = Vector3.new(math.random(4,6), math.random(4,6), math.random(4,6))
            Move.Anchored = true
            Move.TopSurface = 0
            Move.BottomSurface = 0
            Move.BrickColor = BrickColor.new("Brown")
            Move.CanCollide = false
            game.Players.LocalPlayer.Character.Torso.Anchored = false
            game.Players.LocalPlayer.Character.Humanoid:TakeDamage(1)
            y = Instance.new("BodyVelocity")
            y.maxForce = Vector3.new(math.huge, math.huge, math.huge)
            y.velocity = Player.Character.Torso.CFrame.lookVector*80
            Move.Parent = Workspace
            y.Parent = Move
            Move.CFrame = Player.Character.Torso.CFrame*CFrame.new (0, 0, -12)*CFrame.new (0,0,-i)CFrame.Angles(math.random(), math.random(), math.random())
            wait()          
        end
    end
end
Mouse.KeyDown:connect(Move)
