Regeneration rate
Your regeneration rate is the speed at which your character recovers HP.
Rate Math
Your base regeneration rate (BRR) follows one of the following formulas:
- If below 60 max HP (MHP)
MHP / 3
- If 60 MHP or higher
MHP / 6 + 10
Total regeneration rate (TRR) is modified as follows:
- Each ring of regeneration adds 40
- A troll leather armour adds 40
- The moon troll leather armour unrandart adds 40 in addition to the previous bonus
- The regeneration mutation adds 20 per level
- The Regeneration spell adds 100
- Trog's Hand adds 100, and unlike other sources is not affected by the Slow Healing mutation
- The demonspawn mutation Powered by Death adds 100 for every corpse within a radius of 3 tiles per rank, up to a maximum of 700. However, the additional regeneration only triggers when you kill a monster, and lasts 2d8 + 8 per rank turns.
Finally you multiply this result by 1/2 if there is a monster in your LoS and you have one level of the Slow Healing mutation; or by 0 if you have three levels, or only two levels and there are monsters in LoS.
Every turn of 10 auts you accumulate regeneration points equal to your TRR. When 100 are gained you heal 1 HP, and excess regeneration points are carried over to the next turn.
If your last action didn't last 10 auts, the amount of regeneration points you gain is scaled with the amount of time taken. But, there is an exception to this rule: walking with delay greater than 10 auts is treated as if it only was 10 auts. This way, Nagas and Cheibriados' followers won't regenerate/hunger too fast while they are exploring the dungeon.
At 100 MHP your BRR is 26. In order to get 100 BRR you would need 540 MHP. For 50 BRR, 240 MHP. As can be expected, regeneration items are far more efficient at raising your TRR than stacking HP.
Examples
- You have 30 MHP so you use the first formula. Your BRR is 30/3 => 10. It will take 10 turns to accumulate 100 regeneration points and heal by 1 HP. Your healing rate is 1 HP for every 10 turns.
- Same as above, except you have a troll leather armour, which adds 40 to this rate. Your TRR is 10+40 => 50. It will take 2 turns to accumulate 100 regeneration points and heal by 1 HP. Your healing rate is 1 HP for every 2 turns.
- You have 90 MHP which is over 60 so you use the second formula. Your BRR is 90/6 => 15+10 => 25. It will take 4 turns to accumulate 100 regeneration points and heal by 1 HP. Your healing rate is 1 HP for every 4 turns.
- Same as above, except you have the regeneration 1 mutation, which increases your RR by 20. Your TRR is 25+20 => 45. It will take 2.2 turns to accumulate 100 regeneration points and heal by 1 HP. Your healing rate is 1 HP for every 2.2 turns.
- You are a Demonspawn Berserker with Robust 3, Rugged Brown Scales 3, and Powered by Death, at XL27 with 27 Fighting. You thus have 347 base max HP. You are wearing the moon troll leather armour, have been lucky with mutations and gotten Regeneration 3, are wearing a ring of regeneration and the ring of Vitality (giving you 362 max HP), just killed a monster with 7 corpses in sight, are calling upon Trog for divine regeneration, just pulled an Elixir card and got the regeneration effect, and are berserk (bringing your max HP up to 543). Your BRR is 543/6 + 10, or 100. You have 700 from PBD, 80 from your rings of regeneration, 80 from the moon troll leather armour, 60 from the regen mutation, 100 from Trog's Hand, and 100 from the Elixir card's regeneration, for a TRR of 1220, meaning you will gain 12 or 13 HP each turn.
