Resistance damage reduction

Can someone point me to a table/info on how much of a reduction to damage you receive from various resistances?

I think the basics and poison give you 2/3 reduction (single source), or 8/9 reduction (permanent + temporary source).

How about the others?

They vary in a non-intuitive, opaque manner, and is something that I've been lobbying to have changed for a while.

For shard, nexus, nether, chaos, disenchant. the resisted value is equal to

6/(6 + randint(1,6)) so anywhere from 1/7 resist to 1/2

for sound it is

5/(6 + randint(1,6)) so sound is a little better.

for light and dark it's

4/(6 + randint(1,6)) so they're even better yet.

If we wanted a random value, I still think we could accomodate it without such an asinine formula.

Let me confirm:
I get hit by a breath attack of 700, which I resist.

If the attack was shard, nexus, nether, chaos, disenchant: my damage is 350-600.

If the attack was sound: my damage is 292-500.

If the attack was light or dark: my damage is 233-400.

This would be correct, except that the damage is also capped - with different caps for each element, and the resistance calculated after the cap is applied. So for nexus, light and dark, the cap is 400, so the damage is 200-343 for nexus, 133-228 for light and dark. And so on.

Ok: I've thrown this info together:

Fire/Cold/Lightning/Acid/Poison/Time/Gravity: damage = 1/3rd of the health of the monster
other damage types: damage = 1/6th of the health of the monster

caps:
F/C/L/A : 1600
Poison: 800
Nether: 550
Sound/chaos/disenchantment/shards: 500
Nexus/light/darkness: 400
Inertia/gravity/force: 200
time/plasma: 150

Notes:
(1) I cannot find a monster that breathes darkness for the maximum amount. However The Phoenix caps the light breath at 400. Tselakus the Dreadlord can invoke a darkness storm for 440 damage (but this isn't a breath).
(2) The aether vortex shows us clearly which damage types do 1/3rd the health of the monster, and which do 1/6th. In particular Time and Gravity unexpectedly do 1/3rd the health of the monster.
(3) Other information on caps for the most part taken from Ancient Dragons/Wyrms or Zepher Hounds

I should just point out that one of the very small changes I made in my custom version was to drop time and gravity to 1/6 just like every other breath. They're dangerous enough at half damage, I don't know why they need to be buffed in that way too. It doesn't make sense.

I hate time breathers . The one saving grace is that both have low damage caps.

This table lists maximum resisted damage from breaths:

caps resisted (double resisted in brackets):
F/C/L/A : 533 (177)
Poison: 266 (88)
Nether: 471
Chaos/disenchantment/shards: 428
Sound: 357
Nexus: 342
Light/darkness: 228

Notes:
(1) In the case where resistance chops off a semi-random amount, the worst-case scenario is listed.
(2) Values assume that angband rounds down all resisted damages to nearest integer.

Caps for unresisted sound is same as chaos/disenchantment/shard and unresisted Nexus is same as dark and light. (list-mon-spells.h)

Nether = 550 cap HP/6, Cha/Dis/Sha/Sou = 500 cap HP/6 and Nxs/Drk/Lgt = 400 cap HP/6. Unresisted time and gravity have HP/3, but caps are much lower.

I don't know why sound does less damage than four other balance elements (law + chaos = balance). IIRC it didn't used to (except that chaos had 600 cap in old times).

Sure, but the amount resisted is different. (see Fizzix's post above)
