When Harvesting increases by 5% at the end of each wave, this is considered a "Harvesting modification" for the purposes of the Entrepreneur's passive ability and will itself be increased by 50%. This results in an effective increase of 7.5% to Harvesting at the end of each wave even though the description for Harvesting will still display a 5% increase per wave. Combined with the 50% increased Harvesting received from level-ups and shop purchases, the Entrepreneur has a much larger than average return on Harvesting acquired early.
Since the Entrepreneur loses all material at the beginning of a wave, it is wise to spend as much material as possible before closing the shop. Spending any excess material on re-rolls is preferable to losing that material for nothing.
In Endless Mode, the 10% Harvesting Stat lost at the end of each round is unfortunately also increased by 50%.
|Harvesting increases by an additional +8% at the end of a wave (stacking)||Since the end-of-wave Harvesting increases are considered "Harvesting modifications," this is in an effective increase of 12% to the multiplier for a total of 19.5% increased Harvesting at the end of each wave. The description for Harvesting will still display a 13% increase per wave.|
|+20% of your materials at the start of waves||Piggy Bank's effect stacks additively with the Entrepreneur's passive. This will increase the amount of Materials kept at the start of each wave from -100% to -80%, meaning that 20% of the Materials left over after exiting the shop will be kept instead of 0%.
However, it is generally not recommended to purchase Piggy Bank on the Entrepreneur as it will still be preferable to spend as much material as possible at each shop, resulting in a low return on investment.
