Dismemberment

B421
:If injury to a body part before applying the above limit was at least twice what was needed to cripple it, the body part is not just crippled but destroyed.
:A cutting attack or explosion severs a limb or extremity; otherwise, it’s irrevocably crushed, burned, etc.
Given that it takes MORE than HP/2 or HP/3 cripple a limb or extremity (ie HP/2+1 or HP/3+1) it would take HP+2 or HP*2/3+2 damage to destroy a limb or extremity.
==Fantasy==
ability on GURPS Fantasy pg 205 defined Innate Attack: Dismemberment as a Cutting Attack with modifiers:
*All or Nothing
*Delivered by Grappling an Extremity
*Immediate Crippling
This operates differently. Instead of needing at least twice the damage, it requires just the damage needed to cripple, and this generates a HT roll to decide whether or not the cumulative crushing+cutting cuts off.
This is a major advantage!
