Regeneration and Fast Healing Question


Rules Questions


Ok so I am curious, how would Regeneration and Fast Healing work together?

Say I had Regeneration 1 and Fast Healing 1. I would heal 2 points of damage each round right?

Regeneration (Ex)
A creature with this ability is difficult to kill. Creatures with regeneration heal damage at a fixed rate, as with fast healing, but they cannot die as long as their regeneration is still functioning (although creatures with regeneration still fall unconscious when their hit points are below 0). Certain attack forms, typically fire and acid, cause a creature’s regeneration to stop functioning on the round following the attack. During this round, the creature does not heal any damage and can die normally. The creature's descriptive text describes the types of damage that cause the regeneration to cease functioning.

Attack forms that don’t deal hit point damage are not healed by regeneration. Regeneration also does not restore hit points lost from starvation, thirst, or suffocation. Regenerating creatures can regrow lost portions of their bodies and can reattach severed limbs or body parts if they are brought together within 1 hour of severing. Severed parts that are not reattached wither and die normally.

A creature must have a Constitution score to have the regeneration ability.

Format: regeneration 5 (fire, acid); Location: hp.

Fast Healing (Ex)
A creature with the fast healing special quality regains hit points at an exceptional rate, usually 1 or more hit points per round, as given in the creature’s entry. Except where noted here, fast healing is just like natural healing. Fast healing does not restore hit points lost from starvation, thirst, or suffocation, nor does it allow a creature to regrow lost body parts. Unless otherwise stated, it does not allow lost body parts to be reattached. Fast healing continues to function (even at negative hit points) until a creature dies, at which point the effects of fast healing end immediately.

Format: fast healing 5; Location: hp.

What is the difference in the two? In 3.5 Regeneration treated all damage not of the Fire or Acid type to be nonlethal but it doesn't seem that is true in Pathfinder, so how are they different?


They both heal every round.

Fast healing won't save you from death or dismemberment, while regeneration will.

Regeneration usually has something that will suppress the effect for one round. For that round, the regeneration stops working, and the creature can die normally; if they do, regeneration won't bring them back.


They are both fast healing so they don't stack.

The difference is Fast Healing works while you are alive. There is no damage that stops it form working but when you are dead you are dead.

Regeneration is Fast Healing except it works when you are dead and will bring you back to life. You could be negative 1000 hit point and you will come back as long as you didn't take fire or acid damage when you should have died. You will regrow from the largest body part and all other wither and die if not reattached.

Where did you get that? It says it prevents you from dieing not that you regrow after death. So like if someone stabs me while I am down at below 0 HP I don't die because regeneration keeps healing me unless they use Acid or Fire damage in that blow.

As far as not stacking I don't know if they do or not. They are different abilities and different names, just similar effects.

They are separate abilities so they'd both stack.

It was noted by 3.5 that if you arranged for something with regen/Fire or ACid to become immune to fire or acid, their regeneration became fast healing, they didn't become unkillable.

That's the only overlap between the two.

The only difference between the two is that you can shut regen off by hitting its weakness. Otherwise, Regen/1, FH/30 and Regen/30 FH/1 are exactly the same in net effect.

So I would heal 2 points per round, and unless you are hitting me with Fire or Acid I cannot die.. am I a highlander?

Different abilities with different names do stack unless they grant the same "type" of bonus (eg enhancement) or specifically say they don't stack. Neither of these is the case with regeneration or fast healing, so they do stack.

As an example:

YOu meet up with a Pit Fiend, that happens to have fast healing/5 (there are actually epic monsters from 3.5 that have both, btw), and it's normal regen 5/good.

You smack it with a holy sword.

It will not regenerate 5 hp that round. It will, however, still fast heal for 5 points.

IN effect, the fast heal will always heal, even if you null the regen for a round. However, you can still die while fast healing.

Thus, Regen/1 FH/30 is a more powerful combination of the two then Regen/30 FH/1, but in normal circumstances they'll net out the same. The First will simply heal more in periods when regen is 'down'.

They would stack, and unless you are hit with acid fire or something else that halts your regen, you gain 2 points a round.

If you are "killed" (for a creature with regen, this means brought below -CON in HP with no regen stopper applied) your Fast Healing stops until you are -CON. Your regen keeps working even if "killed" fast healing does not.

For confirmation, check out vampires.

That's the whole point of regeneration and it's not always fire or acid . Yeah you can keep hitting a monster to -100 000 hp, they will not die until you stop their regeneration.


Hmm the idea I had was to mix 3.5, toughness and troll blooded with a Spelleater Bloodrager would grant me Regen1/FH1 from second level on.

At that point it is just easier to drown the thing in its own blood.


Now we're getting close to the old favorite question of "can you kill a troll by suffocation or with disintegrate?".

My favorite: if you have no fire or acid handy, just incapacitate it, disembowel it, collect some stomach acid, and apply it liberally. Should do the trick.

Suffocation definitely ("Regeneration also does not restore hit points lost from starvation, thirst, or suffocation"), but Disintegrate no.

It would be reduced to ash and have a number of HP equal to its negative Con score, since as noted in the Death Attack rules a creature who is killed (no matter how they died) is at -Con or below.

From there, they would Regenerate back up to full HP, regrowing lost body parts (i.e. All of them) along the way.


By my reading suffocation will not kill something with regeneration but, without being able to heal the damage from it, it will remain unconscious until healed by a different source.
