Rifts: Foundations of Hope
Using the following optional rule:
Savage Incapacitation plus Death and Defeat table.
If that proves too deadly, we may use Heroic Incapacitation plus the Death and Defeat table.
Heroic Incapacitation – Ignore Wound Modifiers on any Incapacitation roll. Hard to Kill instead provides a +2 bonus to Incapacitation rolls. Instant death is much more unlikely, but still a possibility for some concern.
