Dmg reduc gear

Well... based on robert's post saying he took 503 damage from 1000 needles w/ 50% damage reduction on NIN, it is actually 512 denominator, and not 256...

Nice math!

Your math does look accurate. However, here's a screenshot from ages ago when I tested this stuff:

If you have just a single item that gives 5% (Black Belt), that is 12/256 or 25/512, depending on the precision.

With 244/256 damage, 1000 needles is 953.x dmg
With 487/512 damage, 1000 needles is 951.x dmg

So....?

fuck me... back to the drawing board.

Terra's Staff -20%
Darksteel Harness +1 -4%
Darksteel Subligar +1 -3%
Darksteel Cap +1 -2%
Darksteel Mittens +1 -2%
Darksteel Leggings +1 -2%
Jelly Ring -5%
Defending Ring -10%
Umbra Cape -12%
Minstrel's Earring -30%

-90% in red hp and at night, but it caps out so its pointless

Correct me if I'm crazy, but Umbra cape is 6% not 12%.

Actual % listed:
20% Earth Staff
6% Arhat's Jinpachi +1
9% Arhat's Gi +1
10% Defending Ring
5% Jelly Ring
= 50% = 500 damage which is wrong

256 Denominator:
51/256 Earth Staff
15/256 Arhat's Jinpachi +1
23/256 Arhat's Gi +1
25/256 Defending Ring
12/256 Jelly Ring
= 126/256 = 507.8125 damage which is wrong

Since the Black Belt test casts doubt on the 512 denominator, perhaps it is a 256 denominator and one of those pieces of gear actually overestimates the reduction by 1/256.

(1-127/256) * 1000 = 503.x

If I had to guess, maybe one of the arhats pieces is over by 1/256, if anyone wants to test them individually assuming it hasn't been done.

The alternative is that the black belt is erroneously 24/512.

But yea, testing the individual items should solve this mystery.

out to altepa i go!

[Kainen]

very interesting... 1000 needles w/ only my defending ring... did 898, which is MORE than the advertised 10% reduction.

[Kainen]

OK. All other items seem to pan out w/ the 256 denominator. Defending Ring just seems to be an anomaly.

256 Denominator:
51/256 Earth Staff
15/256 Arhat's Jinpachi +1
23/256 Arhat's Gi +1
26/256 Defending Ring
12/256 Jelly Ring
= 127/256 = 503.90625 damage.

Umm... the item descriptions have no actual bearing on the effects an item gives. SE probably just rounded everything to the nearest % for "display" purposes because it would look really stupid if the item descriptions said "damage reduced by 24/256" or "damage reduced by 19.9214%".

When the game calculates the damage, I would be reasonably sure that it's X/256 reduction, because doing calculations with a single byte of data is easy (and fast).

Right but the confusion here was due to the fact that in every case except defending ring, when SE says "damage taken -X%" they really mean "the greatest fraction of 256 less than X%" rather than "the nearest to X%". For example Jelly Ring being 12/256 or roughly 4.69% instead of 13/256 or 5.08% even though the latter is much closer to the value in the description. D. Ring being 10.16% instead of 9.77% is what threw everyone off, I think.
