Heals FP Only

*Fatigue Only for Regeneration
*Heals Fatigue Only for Healing
*Only Heals FP for Leech
The term appears in http://www.sjgames.com/gurps/faq/FAQ4-5.html#SS5.1.3 where it is talking about Regeneration modifiers, but uses Leech's term for an enhancement when describing Regeneration's cost.
