Shard of Light

The Shard of Light

Weapon (shortsword), Legendary (requires attunement)

''This short sword is one that has been lost to history for centuries…until recently. Given to a young acolyte of Paladine named Neran after a prayer to his god, he used it to kill Caeldor, High Master of Mishakal, who had betrayed everyone at the Temple of Hurim to an army of ogres. As Caeldor finished a ritual to summon a devil from the Abyss, Neran stabbed the Betrayer with the Shard, pinning the Betrayer's body to a stone sarcophagus, where it remained for over 1000 years until it was found recently by a party of adventurers.''

The blade is made of clear crystal that glows with an inner light. That glow can be made as bright as daylight, harming many undead and blinding any others.

This solid crystal blade is a +2 shortsword that gives off light in a 20ft radius.

Once per day, as a bonus action, you can hold the blade overhead and command the sword to shed bright light in a 10' radius that is like full daylight, and dim light for an additional 10' that grows by 5' every round to a maximum of ten rounds for a maximum of 60' each. When you lower the blade, the radiance fades to dim light and persists for a minute.

Once per day, as a bonus action, the wielder can turn the blade into pure light. When in this state, it deals radiant damage instead of piercing and ignores any nonliving matter /physical armor it strikes. While in this state, it cannot harm constructs, objects, or undead unless they are vulnerable to radiant damage. This effect remains until the end of the wielder's next turn.

Once per week a ray of sunlight can be unleashed in a 60ft cone. Anything within the cone is revealed by a true seeing spell. Lasts one minute.
