Alright, I’ll assume non-token user. 4 runs per character per day.
4 x 21 = 84 / 4 = 21 chocolates best case scenario
Multiply this by the number of characters you have. Again, I realize this is best case scenario. There is a very real possibility you will have to trade with people like what happened during the dumpling event. The numbers are still mostly in your favor.
I am only clarifying because there are some people in the game who believe that ingredients aren’t guaranteed to drop, when they’ve been speeding out of a dungeon as quickly as possible while I’ve seen ingredients left lying on the ground. What you get is the only RNG you have to deal with, at least.
