Word of Power: Lux Mortis When the wielder of the enchanted dagger speaks the power word "Lux Mortis", the blade flares with necrotic energy. A wave of dark light erupts from the weapon, inflicting damage upon those within its radius.

• Effect: All creatures within a 10-foot radius of the wielder must make a DC 15 Constitution saving throw. On a failed save, they take 3d6 Necrotic damage. On a successful save, they take half as much damage.
• The runes along the blade glow with a faint, cold light after activating the power, dimming gradually until dawn.
• This ability can only be used once per long rest.
