So between using gems for multiplier and using gems for double shares, which one have more benefit?
Here is my answer: store's multipliers increase income of every girls so it will increase total income, it can stack too and it's good becoz you need money
BUT shares benefit to ALL things in your company: from increase multiplier to decrease upgrade cost, get more keys and increase private show, etc so in my opinion, shares are strong, much better than multiplier in store and you only need 50 to double it. Multiplier can be bought from store but you need at least 100 gems, for spin wheel... this thing is a scam and you need a lot of luck to get multiplier so bad idea. Key drop chances and reduce upgrade cost are 2 main powerful decorations, you will see how ridiculous these girls can cost in late games
I'm still try to figure about different between multiplier in store and multiplier from item but multiplier from item is way better than in store.
