Does Fast Healing stack with Health (from the Fitness power pool)?
Yes. Unenhanced, Fast Healing increases the recovery rate by 40%, while Health increases the recovery rate by 30%. Fast Healing and Health together (both unenhanced) allow a character to recover 42% of their Hit Points every minute, giving a full recovery in under two and a half minutes (141 seconds). With six single-origin Heal enhancements in Fast Healing, the rate rises to 62% per minute, or full recovery in just over a minute and a half (96 seconds). Placing those enhancements in Health instead provides a lower effect (57%, full recovery in 104 seconds). If a character takes both Fast Healing and Health, and places the maximum of six single-origin enhancements in both powers, their recovery rate increases to a maximum of 77% per minute, or recovery from 1 Hit Point to full in 77 seconds.
