Tywhen you place Fps on someone else's Gb, there is a chance to get in return, some Fps, medals, and Bps. The arc boosts these rewards by a percentage which grows for each level. For example, if I win a spot for which the base reward is 10 FPs, 100 medals, and 1 BP, and I have a level 80 arc, which gives a 90% boost, I will win 19 Fps, 190 medals, and 2 BPs.
I got the 1,000-for-500 deal once before. Unfortunately I was at roughly 450. Now I am sure to always keep at least 1,000 diamonds handy, in case something like that ever happens again.
Right next to the option to purchase FP with coins, there is an option to purchase FP with diamonds as well. During the May Madness sale I believe there was an option to purchase FP with diamonds, but this option is much more rare and inconsistent (only during special sales).How do you get FP that you can buy? In one of my worlds, I have 30 FP I can buy with gold and haven't bought that many. In my other world, I've bought many FP with gold and have hundreds more that I can but.
