No there is a max amount of drops you can get from parties. Keeping max plunder and increasing your base stats lets you get max drops with less hits but you cant get more. The only way to get a little bit extra per party is to buy the drop booster pack in the shop for real money
Max plunder gets you the most out of parties. More money and gets you drops easier. You get it by spending money on tutors. 15 million spent on tutors all up per 1kcs of your stats, 15 billion spent on tutors all up per 1mcs of your stats. So for you it would be 258 x 15,000,000 = $3.9 billion (rounded up). Better to be over instead of under max plunder. I usually recommend work your way to 15b soent on tutors then you dont have to worry about it again until you reach 1mcs
Kcs means thousand combined stats. Its when your base stats (the 2 numbers on your profile) add together to = a total of 1000 - 999,999. Mcs means million combined stats. Its when your base stats = 1,000,000 - 500,000,000
There's no info on how to obtain this so far. It'll probably be store-exclusive or there'll be a story that offers it as a reward unless it's an error on the devs' part for excluding it from hunt boxes
Probly but not worth the effort. Just keep max plunder and hit when you are on. Or if you really wanna find out just do some testing yourself. But i dont see the point in being on a game that you only want to put minimal as possible effort into. At that point may as well uninstall
Theres only 1 way to upgrade your dorm. And thats by leveling up your furni ane having something in each spot
