$ Scrolls are items that can be activated in order to increase the total amount of funds your accounts has gained. This is not to be confused with donating via the Webstore. Gaining funds by using scrolls will progress you towards higher donator ranks. Scrolls themselves can be traded, but once activated, they are bound to your account. Scrolls can be activated in bulk by right clicking them.
Currently there are 5 different variants: 1$, 5$, 10$, 25$ and 50$. The 1$ scrolls can be combined into 5$ scrolls via Combination.
