20 Hearty Recipes (200 Sweet, 2000 Sinister) to get a RNG bundle.
Seems to be wothwhile.
If we get 16 Sinister per week (20 for a little amount of people finishing second boss in Prome HM) and we have three weeks (48 respectively 60 Sinister at all), we need to get 1952 (1940) per Lugbug (976 (970) per week) to get one bundle.
Please correct me if I am wrong
