Sunstone - caraminden/anathema-roguelike GitHub Wiki

The Sunstone is Sol's weapon of ultimate power, once his corruption has spread across the land via his Temples Sol plans to unleash this artifact upon Umbra destroying all darkness, killing Nyx and leaving Umbra in a state of permanent daylight.

Every 50 Segments the Sunstone gains 1% power, and each time a Temple is Desecrated it loses 5% power.

Each percent of power the Sunstone gains increases the Light level of every Location by 0.5%

If the Sunstone ever reaches 100% the Player immediately loses the game.
