Good luck with that, Chloris is a terrible source for coins of balance, 5 Kis for a CHANCE at one stinking coin and thats if you proc yellow. senda takes 2 KIs is a much easier fight (due to the Kis) and always drops at least 1 coin if you don't proc yellow.OR...OR, as a 'healthy' alternative for those Coins of Balance, I can go to Tahrongi, and farm up a Chloris pop (which will take atleast 30 minutes from scratch), an Ursurpur pop (which could take a couple hours like tristia) or kill 3 Myrcomelons (yay refresh rods).
Myrcomelon is also a bad source with his low drop rate and can be very annoying low man. tho not hard.
