High HP and Healing

The healing rates given for natural recovery, first aid, magical heal-
ing spells, the Regeneration advantage, etc. assume someone with
human-scale Hit Points; that is, with fewer than 20 HP. Those with
more HP heal in proportion to their HP score. Multiply HP healed by 2
at 20-29 HP, by 3 at 30-39 HP, by 4 at 40-49 HP, and so on, with each
full 10 HP adding 1 to the multiple.
