Lods of Emone

The Lods of Emone modification introduces special coins into the game that can be exchanged for in-game FTB Money currency. You can spend either a single coin or an entire stack - to do this, you need to hold Shift and press the right mouse button. The mod's feature is that the coin denominations are specified through NBT data, allowing you to customize their value according to your needs. You can also choose which denominations will be displayed in the creative menu and in JEI according to your preferences.
