General Guide
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. Support weapons can be a great source of early Harvesting as well.
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.
Synergies
Crown grants +10 Harvesting and an additional 10% increase to Harvesting at the end of each wave.
Since the end-of-wave Harvesting increases are considered "Harvesting modifications," this is in an effective increase of 15% to the multiplier for a total of 22.5% increased Harvesting at the end of each wave. This is the highest possible per-wave Harvesting multiplier achievable. The description for Harvesting will still display a 15% increase per wave.
The effects of Piggy Bank will trigger after the store is closed at the same time as all remaining materials are lost. This means it will generate materials equal to 20% of the amount remaining when the shop is closed, and those materials will be kept into the next round while the rest will be lost. Effectively, this reduces the amount of materials lost at the start of each wave from -100% to -80%.
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 very little return on investment.
