About this Mod
Basic Gameplay
- Added replication cores of different qualities to copy items under various conditions.
- Defeating the Ender Dragon automatically grants all nearby players materials to craft replication cores: Dragon Soul Crystal. Drops 3 on the first kill and 1 on subsequent kills (configurable in the settings file).
- Replicating items requires a Replication Table. Each replication consumes experience levels, calculated based on the item count and number/levels of enchantments (configurable in the configuration file).
- Experience cost formula:
Final Cost (rounded up) = Item Count × Item Cost + Sum of (Enchantment Level × Enchantment Cost)
