Drop rates are abysmal no matter where you farm. My favorite spot is Fuyuki X-G since it can beaten just by attacking with Buster cards and gives decent Bond EXP.

I tend to get up to 10 bones a day there, keyword being UP TO lol, but it is usually a minimum of 5

@QuinnJeriko13

my favorite place to farm bones is in septem

I use in Fuyuki Unknown coordinates C

C has technically the best drop rates, but it really takes a toll on your sanity lol, since you have to get through the loading screen so MANY time. Not to mention the bone drops is all it has, everything else is non existent

I know it’s rng but for a short time I actually got bones more often at X-G than X-C.

Weird Rngsus.

The overall % is just slightly better at C, so (22AP vs 23AP basically), so it's no surprise.

Drop rate per AP at XC is better but you have to run it a lot more than X-G. However XG seems to drop more often within less runs even though you spend more AP per run
