Scrolls are one time use items that you can buy in the shop. Each player has only one slot for scrolls and you cannot stack more than one scroll on top of each other. Scrolls are limited in numbers in the shop and the amount is shared among the players.
The chance of a rare scroll dropping is dependent on the rank of the last boss fight:
- Rank S = 30%
- Rank A = 20%
- Rank B = 10%
- Rank C = 5%
Each rare scroll can only be obtained once per run.
