Sapphire Quads in Beadeaux drop Flood and Water IV. Shouldnt be a horrible drop rate with th5
Give it a try sometime, with TH7-8 (couldn't proc 9 because they die too fast). I gave up when I realized I didn't care whether my friend's RDM mule could cast Water IV.
You could also... Idk, just like... do Abyssea. Certain crafting materials that drop from gold pyxides make for some nice chumpchange, and there's the random piece of AHable gear off NMs that'll fetch 200k+. New NMs also drop tier pop items, which sometimes sell for a decent amount.
If you want to make a big sum of gil quickly, level up SCH, make friends with a MNK, get a discernment abyssite and learn how to speak Japanese. 3m Velox Harness, 5m Ocelot Trousers, etc.
