I second what was already said, just wanted to add a bit on feet. Pascerpot (crawler) is pretty easy, he likes Banishaga III and Sticky Thread though, drawback is he has the lowest droprate for NIN (something like 20%). Iku-Turso (sea monk) is a dirty cheating bastard, among the more obnoxious things he will do is Maelstrom (causes silence aura, bad for shadows), he also likes to throw out -ga IV at the worst possible moments, droprate is around 35%. Personally not worth it to me, you can kill 2-3 crawlers in the time it takes to kill one sea monk. The third option in this zone is Lord Varney, a timed pop and easily soloable with NIN/DNC if I'm not mistaken, droprate here is around 50%. He has a stun/knockback move that can get you in trouble, best spot to fight him is near Conflux 5, place yourself in the walled area by the tunnel, he won't be able to knock you back in that spot. The quest, UGH, this is how I got my feet for both NIN and BLM, it took me at least 20 game hours (BLM was done first, NIN about an hour later), this is an absolute last resort option if you want my opinion.
