Domain Expansion: Cathedral of the Last Eclipse

When invoked, the world fractures like stained glass — light shatters into drifting shards, and the battlefield is swallowed by a colossal gothic cathedral suspended in a starless void. A black sun hangs behind a circular rose window, radiating dim silver light that casts long, warped shadows.

The floor is polished obsidian, reflecting not what is, but what could have been. Massive pillars stretch impossibly high, vanishing into darkness. Every footstep echoes like a tolling bell.

• Gravity feels slightly heavier, as if the air itself mourns.

• Shadows detach slightly from their owners, lagging half a second behind movement.

• A faint choir hum reverberates through the space, though no source can be found.

Sure-Hit Effect: Judgment of the Black Sun

All enemies within the domain are marked by eclipse sigils over their hearts. These marks:

• Reveal their exact location at all times within the domain.

• Cause radiant + necrotic damage whenever they attempt to lie, hide, or teleport.

• Accumulate “Guilt” stacks whenever they deal damage. At 3 stacks, chains of black light erupt from the floor, restraining them for 1 round.

Additional Effects

• The caster can step between shadows as bonus actions.

• Healing magic used by enemies is reduced by half.

• If an enemy drops to 0 HP inside the domain, their shadow remains behind and fights as a weakened wraith for 1 round.

Flavor Variations

• The cathedral could reflect the caster’s faith, trauma, or ambition.

• The black sun could whisper secrets only the caster hears.

• Stained glass windows may depict moments from the enemy’s past failures.
