Upgrade stops offer four cards. Three cost coins. One costs Robux. There are 21 cards in five rarities. Buying a card raises the next price of that rarity. A card can roll up to a higher rarity and grant several levels at once.
Price ladder
| Rarity | First buy | Rise per buy | Levels if the card rolls up |
|---|---|---|---|
| Common | 100 coins | +20 | 1 |
| Rare | 250 coins | +50 | 2 |
| Epic | 500 coins | +100 | 3 |
| Legendary | 1,000 coins | +200 | 4 |
| Mythic | 10,000 coins | +1,000 | 10 |
Read the climb as each buy of a rarity adding its step to that rarity's next price. The total for n buys is n times the first price, plus the step times n times (n minus 1) divided by 2. Five Common cards cost 700 coins. Ten Common cards cost 1,900. Driller's discount is not in that formula. At level 2, Driller cuts Drill Power, Mega Drill, and Power Slam by 50%.
The community wording of the climb is loose. If your in-game price does not match the next step, trust the number on the card.

What to take
For boss walls, RPM Overclock, Ultra Drill, and Power Burst are the named trio. Early, while cards are still Common, Drill Power moves the Grass through Clay walls. Fuel Storage and sack space are comfort buys, not substitutes for wall damage. Team Health and Health Regen matter once Toxic and Frozen hits stick. Buy Firepower, Sharpness, or Blast Power only for the weapon the party actually uses.
Executioner's level 4 perk is described as a free upgrade, chosen from three, each time you beat a boss. That is a boss reward, not a discount on the coin ladder.
Cards last for the run. They do not carry into the next descent unless a church save covers the gear you stored. Cards themselves are not listed as church gear.
