Damaging Shield throw hint:
Once you lock onto all the targets you want to throw at, flick the Nunchuk instead of releasin the C button for a Focus Increase Shot.
Deflect bullets and lasers at enemies without ranged attack first and not the gunners. If you kill the gunners first you won't have anything to deflect at the other enemies.
