Version 0.28: This article may not be up to date for the latest stable release of Crawl.

Your regeneration rate is the speed at which your character recovers HP. It is affected by many things, almost all of which stack.

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

So for every max HP below 60, BRR increases by .333..., and every MHP above 60, BRR increases by 0.166...

Total regeneration rate (TRR) is modified as follows, in this order:

Because the last two effects are applied last, they are not modified by any other factors and can even heal deep dwarves.

Every turn (10 auts) you accumulate regeneration points equal to your TRR. When you accumulate 100 points, 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; your regeneration rate will remain consistent regardless of how quickly or slowly you are acting.

At 100 MHP, your BRR is 26. In order to get 50 BRR (regain 1 HP every 2 turns), you would need 240 MHP; for 100 BRR (heal every turn), you would need 540 MHP. Items or mutations that increase regeneration are far more efficient at raising your regeneration rate 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.
  • 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're wearing a troll leather armour, which adds 80 to this rate. Your TRR is 25+80 => 105. You accumulate 100 regeneration points and heal by 1 HP every turn, with 5 left over. Your healing rate is 1 HP every turn, with an additional HP every 20 turns.

History

  • Prior to 0.28, the Regen+ property gave a bonus regen of 100 (1.0 HP/turn) instead of 80.
  • Prior to 0.27, the Regen+ property gave a bonus regeneration rate of 40 (0.4 HP/turn) instead of 100.
