Spectral Relay

The Spectral Relay is a block added by Astral Sorcery. It can either be used to bring more starlight to a Luminous Crafting Table (or any of its upgrades), to set the target Constellation of an Attunement Altar, or to provide items for an Iridescent Altar. They can hold a single item.

When placed in a multiblock structure (as described below) with a clear view of the sky and a Glass Lens put into it, the Spectral Relay will bring more starlight to the closest Luminous Crafting Table (or any upgrade) in a 16 blocks radius around itself. Multiple Relays in a 16 block radius will have diminishing effects.

When placed around an Iridescent Altar on the sooty marble, Relays will be highlighted during crafting, showing an image of an item to place on them to continue crafting.

Construction
