Including camera angle into .Move direction

Hello! I am trying to code a dodge ability that will also factor in the y-axis (up). The expected function would be the player is moved a certain distance, if the player is looking up and standing still, they would dodge upward. Currently, this only affects the X/Z axis.

Additionally, is there a way to slow the movement by some controllable number?

 private void OnDodge()
 {
         if (dodegTimer == 1.5f && allowDodge)
         {
             Vector3 inputDirectionForDodge = new Vector3(_input.move.x, 0.0f, _input.move.y).normalized;
             Vector3 inputDirection = new Vector3(_input.move.x, 0.0f, _input.move.y).normalized;
             _targetRotation = Mathf.Atan2(inputDirection.x, inputDirection.z) * Mathf.Rad2Deg + _mainCamera.transform.eulerAngles.y;
             Vector3 targetDirection = Quaternion.Euler(0.0f, _targetRotation, 0.0f) * Vector3.forward;
             _controller.Move(targetDirection.normalized * (dodgePower * Time.deltaTime) + new Vector3(0.0f, _verticalVelocity, 0.0f) * Time.deltaTime);
             //Debug.Log("This is a successful dodge run");
             dodgeActive = true;
         }  
 }
