I'd meant to go back and test more before posting, but I can't seem to find time, so I'll just post what I have.
I was looking over my Death Resist set in response to the Ambuscade Frog deciding to death me twice in one fight. For PLD, that's pretty much just rings. thing is, there's 3 of them.
Warden has a visible value(+10)
Eihwaz is reported as +10("+10% resistance to death, according to FFXI Premium guide 2013",

But I couldn't find anything on Shadow Ring's potency anywhere. And I sifted through age old KI posts, and Google translated JP wiki. JP wiki did have something vaguely phrased about it being the potency of a job resist trait? but didn't explicitly state a value.
I've just been using the newer two rings with the thought that stats tend to increase over time, and being old and hell, Shadow Ring probably has lower potency. But I didn't
Know so I tested.
Angra Mainyu in Dynamis Beaucedine is an amazing test mob for Death. Once he chainspells and come back from warping away once, he literally does nothing but Death and the Rare TP move.
You can just lock in Twilight, RR, claim him him, then get Death'd. each cycle took maybe 20 seconds. 10 of that being waiting for RR to pop up.
Anyway, Results.
121 deaths cast.
32 resists.
96 dead.
26.4% Proc rate.
This is a small sample size, so the real value could like +/- 8% or so. But it's still waaay higher than I expected. I'd like to increase the sample size at some point, but haven't been able to find the time. Still, this is enough to tell us something useful. Use Shadow Ring over one of the newer rings.
Part two - Resist all status Ailments gear.
Now I admit, I screwed this test up pretty well. And it should be redone, but even so, I think it probably still shows how this works. Or rather, doesn't.
Tested with Adamas, reportedly +20 resist all, and Staunch Tathlum. Issue being that I typo'd my lock command and wasn't actually wearing Staunch for a portion of the test. Which I didn't mark, so I don't know how long. And Adamas value is reported, but not well confirmed. So this whole test is kinda iffy.
Anyway. Ate 35 deaths wearing Adamas, and sometimes Staunch. And never resisted. Which is I guess.. possible, but unlikely assuming Adamas' value is correct, and that resist all status gear works on death. I'm inclined to say it doesn't at this point. But I do think I should retest.
