Injury Tolerance (No Eyes; No Signature, +20%)Take one, the other, or both, but both might be redundant.
The way to stop our own attack from doing damage is to use the No Injury modifier.
This modifier needs to be modified in meta though because we don't want it to be on all the time.
The opposite of
No Injury, -50%is
Injury, +50%To Injury we need to add the limitations Accessibility, HP is positive, which is about -20%, and Reflexive, which is +40%, and Always on, which is -10%. This is altogether +10%, and +10% to 50% is 5%. Altogether, this is a +5% enhancement then to stop all damage beyond 1 HP.
Statistics: Crushing Attack 1d (False Swipe Modifier, +5%; Melee, Range C, -30%; No Blunt Trauma, -20%; Sorcery, -15%) 
Notes: 2d is an acceptable maximum.
