Regeneration

Your wounds heal very quickly.

Increased natural healing rate
Severed limbs regrow over time

Regeneration is a physical mutation which improves the player’s natural HP regeneration rate and allows the player to regrow lost limbs, given enough time. This regeneration rate is in addition to the creature's normal HP regeneration rate, which is ${\frac {20+2\times ({\text{Willpower Modifier}}+{\text{Toughness Modifier}})}{100}}$.

Note that only one limb can be regrown at a time. Additionally, if an entire arm is lost, then the arm and hand will be regrown separately.

Regenerating Limbs

The amount of time before a limb is regrown is determined by the following formula:

5000 - (400 * Level) + 1d((11 - Level) * 1000

Advantages & Disadvantages

This section is opinion-based. Your mileage may vary.

Advantages

• Gives the player easy access to limb regeneration, which normally requires specific resources, such as ubernostrum injectors, regeneration tanks, or hyperbiotic beds. Additionally, there is no limit on how many limbs a player can regenerate through the Regeneration mutation, while a player could, for example, run out of ubernostrum injectors.
• Increases the player’s passive HP regeneration.
• Slightly decreases the amount of water a player requires, as they will have to rest for a shorter amount of time when healing after a fight.

Disadvantages

• Very high Mutation Point cost at character generation.
• The bonus to passive HP regeneration is too low to make a significant difference in most fights.
• Limbs are dismembered very infrequently in Caves of Qud, and the “normal” methods of regenerating limbs are common enough to regrow any lost limbs.
• hyperbiotic beds are easily found in Grit Gate, so a source of limb regeneration is always available if the player has a recoiler.
