Looking for stuff like the Barghest’s growth points, or a Juggernaut’s kill points.

Juggernaut (Soul-Powered ability), Barghest (Feed ability)

I’m looking for things similar to these, because I discovered that the Juggernaut has no limit to his kill points, but eventually it plateaus in usefulness since it doesn’t increase hp or damage.

I’m thinking of just adding a reskinned version of the Feed ability, but with no growing after 4 points, and adding it to creatures I want to make stronger, but I would really like to know if there is anything else that is similiar to these abilities.

Any undead with energy drain and vanpires with blood drain can get temporary hit points/healing by using those abilities.
