P96 defined as Common for trigger limitation (expensive, somewhat hard to find) and it's -30% due to the usual -20% being multiplied 1.5 for "illegal, addictive, or otherwise dangerous" (probably the 1st, illegal to hurt people, explanation is "illegal on most worlds").
- just like Sexual Energy for Dependency disadvantage on H66 which appears to be FP/HP lost to leeching to restore HP
- as compared to Trigger: Injury which is "Very Common" since it is accessible through self-injury, which is easier to do than injuring others
- there is not actually an "injure others" option though, only "injure them with Leech and get HP from it".

Trigger, Extended would be lower-value if the HP activated something for a longer period.
One thing that seems kind of unclear though is if HP/FP is used to fulfill a "cost" (trigger an ability limited like this, or to stave off HP loss from dependency) is if it would have it's standard effects (like healing HP as Leech would normally do).
Presumably since triggers/dependencies often use up VALUABLE quanta (ie buying drugs) since you don't need to pay for this (instead you are stealing vitality from others) in lieu of not paying money perhaps you should not get the usual effect when it goes to that.
