Your wounds heal very quickly.

Increased hit point regeneration rate

Severed limbs regrow over time

Preliminary testing seems to indicate that this mutation gives you a flat bonus of ~.23hp/Turn (for reference vanilla regen with 16 Toughness/Willpower is .2hp/turn). Each level increases the regen by ~.04hp/Turn. These bonuses don't appear to scale with your toughness or willpower.

  • Better health regeneration.
  • Regrow limbs slowly. This takes many in-game days.
  • Slightly reduced food/water consumption as auto-heal takes less time.


  • High MP cost of 5.
  • Can make untreated Glotrot extremely annoying as your tongue will occasionally regrow, then bleed and rot again, constantly interrupting your attempts to travel and making you lose HP.
