Okay i just checked her stats - apparently she only
needs 4 skills ups to be max skilled. Maybe thats the reason they implemented such a low drop rate for her.. still thats quite bad. Rayleigh and Whitebeard skillbooks werent that bad from what i remember.
I thought of that too... but we've had plenty of secret stage units requiring 4 skill ups as well and their encounter rate was decent enough with mass runs. Boa shouldn't be below that percentage just because she's a legend unit.
Comparably, Whitebeard had a decent drop rate with Kraken and didn't feel completely insurmountable. Rayleigh I didn't finish, but frankly we got those books early with the day/date Halloween forts JPN had.
It's just all feeling kind of scummy, given the laundry list of negatives lately.
edit: I did find that running a BB STR shooter team is a LOT faster than even Legend Ace. Key is having Absalom to half the damage on the last stage so that you only take 50k instead of 100k.
The Ace team or any full shooter team just requires too many mechanics to slog through Domino which is already way too slow as-is. I've settled into a BB team as well, it's just way more comfortable nuking that boss stage with specials.
Though, still, I'd gladly take one of your many Ace dupes off you. Just one please.
It really is painful. I've been doing 15 stamina because I can't beat 30 at the moment. It's probably not the brightest decision, but I really want Boa books if I can get them, and I'm still earning decent exp at my level.
I've probably done over 100 runs or so at this point and gotten 2 books. I wish I'd kept track, but I didn't get my first book to drop until 4 days of farming. Looking it up on the reddit, 15 stamina has about a 2% chance and 30 stamina had a 7% chance.
I've gotten the minirhino up to level 52 just by feeding copies to itself by now.
Anything Rhino just drops way, way too much.
As per Boa, I'm not gonna lie... the safest bet is probably in the range of a minimum 400 30 stamina runs. It's grotesque and especially since you're running 15 stamina, it might be anywhere from 1.5x to 2x the amount of runs you'll need. The community rarely collects data analysis for 15 stamina runs, so even what I'm saying is just an estimate.
I don't have Boa myself, but would still personally like to stash about 20 books if I can get them. I'm going to run the event myself thru the rest of the week and whatever I end up with, I end up with.
If I could lend my team over to help with your farming, I would. All I can say is keep it up and good luck with drops on your end!
