My script keeps increasing the damage/items added each time it runs, how do i fix it?

So i have this looped function, once the other player is hit they take damage and this little shock wave appears, but each loop the damage increases and more shock waves are added, i'm not sure what's causing this. Script -

---------------------------------------------------------	
HBoxes.Touched:Connect(function(hit)---------------------
---------------------------------------------------------
		local Humanoid = hit.Parent:FindFirstChild("Humanoid")
		if Humanoid and Check and Barrage == true then
			Check = false
			Humanoid:TakeDamage(BarrageDamage)
			local Wave = RS:WaitForChild("Hit"):Clone()
			Wave.Parent = hit.Parent:FindFirstChild("Torso")
			Wave.Position = hit.Parent:FindFirstChild("Torso").Position
			Wave.Size = Vector3.new(math.random(4,10),math.random(1,3),math.random(1,3))
			Wave.Orientation = Vector3.new(math.random(0,360),math.random(0,360),math.random(0,360))
			Wave.SFX:Play()
			wait(0.05)
			Wave:Destroy()
			Check = true
		end
	end)
end)
