Probably $2500 or so.

A good $2000 of that was on FGs prior to the first guaranteed rainbow gacha (which no one was expecting for another half-year). Considering most of my rolls were garbage (even during the slice gacha that supposedly had increased rates), I do regret whaling that hard. Now I just do the 100/300 gold rolls and refill on FGs around once a month.

But the rainbow gachas we've gotten in the past three months have been fairly reasonable, bridal Cactus aside. I've done every ticket gacha, the first step-up gacha, the current step-up gacha, and steps 1-4 of the other two gachas.

Since I'm not really spending on anything else these days, and the only other Nutaku game I play is Aigis (which hasn't improved anywhere near enough to warrant going back to whaling), I don't mind spending on FKG now. Especially since it does seem to be actively improving.
