Island Chunk Booster Modules 
are special items that let you change the buff of an Island Chunk Booster Block on a Progression Island. These blocks are found on Progression Islands and normally give a base buff, but placing a Module on one will replace that default buff with a new, stronger one.
- Modules can be added, removed, or swapped at any time for free.
- When a Module is applied, the original buff is disabled and your new Module takes effect in that chunk.
- Modules are found in Adventures and other tables.
