The best places to farm (x)

[Unhappy Camper]

Figured I'd drop what I found were the best spots for some of the more important items to farm, since a lot of times I looked for specific rooms to siren specific enemies to increase the chances of getting the drops I needed. This is of course, aside from pink tails which can only be farmed in 1 room anyway.

Black Tail: B2 of Lair of the Father, sirens always call Armored Fiends here
Blue Tail: B3 of Passage of the Eidolans, shortcut to the Feymarch and then exit back to the cave, Sirens always call Thunder Dragons
Yellow Tail: Outside of the Passage of the Eidolans, Sirens always call Yellow Dragons here.
Green Tail: Outside of the Sealed Cave, Sirens always call Green Dragons here.
Red Tail: The First Level of the Lunar Core (where the music from the Giant of Babil plays), Sirens always call 1 Red Dragon here, also a good enemy to grind xp on, as the drops pay for the sirens, see if you can steal Crystal Rings while you're at it, and you can also get Wyvern Lances, which are good for Kain to use on these to reduce the incoming damage he takes from them.

Rainbow Pudding: Same place you farm Pink Tails is the best but barring that you can also use Sirens in a room on the Right side of B2 of Antlion Lair to kill the Yellow Puddings but the drop rate is ultra rare.
Silver Apples: Mount Ordeals Summit, Sirens always call Liliths here and as a bonus you can save scum at the savepoint if you really want.
Ribbons: B1 of Lair of the Father, Sirens always call 1 Dark Sage here. This is also the best way to farm Soma Drops
Crystal Rings: Steal from Red Dragons while farming Red Tails in Lunar Core
Cursed Rings: Mount Hobs Summit, Sirens always call 2 Spirits here.
Dragon Whisker: B3, B4, or B5 of Lunar Subterrane, Sirens call 2 Blue Dragons
Artemis Bow: Unfortunately not a good one as Moonmaidens always spawn with something else, the best is B1 of Lunar Subterrane, as Sirens will summon either 1 Dark Sage, 1 Dark Sage and 1 Moonmaiden, 1 Dark Sage and 2 Moonmaidens, or 3 Dark Sages, you can also farm Ribbons and Soma Drops doing this at least. I have yet to get one myself.
