Health regeneration - 1982 to 2022
The protagonist regenerates health automatically over time.

Health regeneration: Slow - 1991 to 2021
Health regenerates so slowly it won't save you even if you get a few moments of peace. Requires long downtime between battles to help at all.

Health regeneration: Fast / Instant - 2001 to 2022
Health regenerates fully in only few seconds when not taking damage, making it very useful even in middle of combat.

Health regeneration: Moderate - 2001 to 2018
Health regenerates at a moderate speed, a breather may help you survive, but you won't get back to full health without still spending some time out of harms way.

Health regeneration: Stunted - 2001 to 2017
Health regeneration works only up to a point (such as restoring a partial segment to full but not beyond it, or up to a certain percentage of full health), never fully restoring it.
