Eclipse Blade

Weapon

Legendary Requires Attunement

This sentient longsword deals an additional 2d6 radiant damage on a hit.
Once per day, you can use an action to summon a solar eclipse. All creatures within 30 feet of you must make a DC 18 Constitution saving throw, taking 8d10 radiant damage on a failed save, or half as much on a successful one.

Description: A sleek, black longsword with a blade that seems to absorb light. It feels cool to the touch and hums with power.
Appearance: The blade is etched with intricate runes that seem to glow faintly when the sword is drawn.
