Skeletons: Uleg Range (near-permanent weather means just need 10 kills)
Goobbue: Boyahda
Any: any
Birds: leypoint
Lizards: Kuftal if solo (lot of lizards in a confined area, but slow repop), Cape Teriggan in a team (more spread out, but faster repops means more potential kills)
Wamoura: Mount Zhayolm (either right behind the first gate with no more than a few people, or way past the dahaks for a large group). Highly suggested: 1 mnk/dnc + 1 mnk/rdm; having a real mage as support is even better.
Beasts: Uleg Range rabbits/tigers (team up with thf/dnc/blu's working on daggers/swords); can easily hit 100/game day
Bombs: Djinn in NW Battalia_S. 2/3 are EP, 1/3 are too weak; can still get over 50 per game day solo; got 75 when teamed with a smn; alt: Abyssea djinn in Vunkerl (~180/hr with a high-kill team)
Lizards: Kuftal if solo, Cape Teriggan in a team
