(is from Hades)
Centurio X-I Quicksands Caves
Drops plenty of gil, some scrolls (Stonega II is rare but sells for 100k!) and other normal antica drops.
While camping him, I usually clear out the Antica in the room for rotten meat (worthless, really, but NPCs for like 10 gil so hang onto it if you have space), Antican Robes, which desynth into cotton thread and cloth depending on the crystal you use, and Antican pauldrons which sell for about 1-2k. (Also desynthable but much higher level). You need to be 75 to solo him, and even that's kinda rough if you get too many links, but I do fine with RDM/BLM.
Also while camping you can take out the spiders in the room for webs (drop rate is sheer suck though I've never gotten one) and the worms for ores and flint stones.
