Best way to get your machine to 1000 coins in greedmode.
1. Reroll runs until you get the d20 on 1st floor.
2. Find a floor with a battery charge in the shop, complete the floor without picking up coins, d20 the drops, buy the battery over and over to keep d20ing, you'll get a shitload of everything including items from golden chests, (dont actually take these unless theyre damage ups though), you'll need to do this for 30 mins to an hour.
3. You're looking for 2 things from this process, a fool card and either a d6 or a blank card and dice shard or perthro rune. Keep the fool card in another room so you dont d20 it.
4. When you've got that, you also need to start buying items from the shop until you get "the battery" item (you can also use the shop to get your blank card/d6).
5. Reroll the items you got from d20ing until you get glowing hourglass, take whatever you want.
6. Take the fool card and hourglass down with you.
7. When you get to super greed, kill him, use the fool card, go back into the room and start donating. If you run out of money or it jams, use the hourglass. For whatever reason when you have double charges with the battery you can use it an infinite number of times.
8. Congrats, you donated 1000 coins in a single run. The setup is long but its way quicker than doing it the normal way.
