Not terribly exciting, but I have the TOD for Shankha, a Uragnite NM in Bibiki Bay (Purgonorgo Isle).
I don't know what his spawn behavior is, but I saw him at:
I-9 in the Purgonorgo Isle part of Bibiki Bay that you get to via the Manaclipper or by using your +1 blue bathing suit top that has enchantment: Teleport-Purgonorgo Isle.
I hadn't camped him or anything; he was just sitting there unclaimed, with no one else in the zone but a couple of low-level ppl. who were nowhere in sight.
He checked as "Impossible to Gauge," so I had to go for it. ^^
He dropped a level 59 R/E shield:
Adoubeur's Pavice
Def. 15
"shield mastery" +1
all races
WAR/RDM/PLD/BST/SAM
Anyway, his TOD was 21:29 (9:29 PM) EST, tonight.
Vana'diel time 23:28 Earthsay, last quarter moon 45%.
It was an easy fight as 75 RDM/BLM. I Chainspell nuked him with Thunder III, but I don't think I actually needed to 2-hour.
That's all; just wanted to share.
