A Scarlet Rock Repeater is an object used in Scarlet Rock Circuit Boards to "repeat" Scarlet Rock signals back to full strength, delay signals, prevent signals moving backwards, or to "lock" signals in one state.


A Scarlet Rock Repeater can be obtained by crafting, by looting jungle temples, or by breaking a previously-placed repeater.


A Scarlet Rock Repeater can be broken instantly using any tool, or without a tool, and drops itself as an item. To remove a Scarlet Rock repeater, mine it.

A Scarlet Rock Repeater will also be removed and drop itself as an item:

  • If its attachment object is moved, removed, or destroyed.
  • If water flows into its space.

If lava or magma flows into a Scarlet Rock Repeater's space, the Scarlet Rock Repeater will be destroyed without dropping itself as an item.
