How to fix onTouch Function Delay?

https://www.youtube.com/watch?v=7Cf5Olp3tJ0

The Sword was suposed to damage any humanoid that it touches on the first swing but the damage function is being activated with a delay for some reason and it is making it only damage things ontouch after the animation is done.

The Code:

  if keyPressed == Enum.KeyCode.Z and Toggled == true and AnimOn == false and ZAttackCD == true then
   AnimOn = true
   ZAttackCD = false
   Humanoid.WalkSpeed = 0
   ZAttack:Play()
   wait(0.25)
   TParts.Trail.Enabled = true
   local Conn
   Conn = TParts.Touched:Connect(function(hit)	  
   if hit.Parent:FindFirstChild("Humanoid") then
    if not hit.Parent.Humanoid:FindFirstChild("BValue") then
     local dtag = BValue:Clone()
      dtag.Parent = hit.Parent.Humanoid
     hit.Parent.Humanoid:TakeDamage(15)
     game:GetService("Debris"):AddItem(dtag,1)
     wait(1)
     Conn:Disconnect()
    end
   end
  end)
   wait(0.85)
   TParts.Trail.Enabled = false
   ZAttack.Stopped:Wait()
   AnimOn = false
   Humanoid.WalkSpeed = WalkSpeed
   wait(10)
   ZAttackCD = true

Summing up:I want to make it so the sword damages while the char plays the animation of the first swing, not after nor before.

Any help would be appreciated, thanks.
