Argetlam (Claíomh Solais)

The legendary sword of the war god Nuada, reshaped into a silver prosthetic capable of being wielded alongside a bright silver light.

Argetlam allows the user to cast the cantrip Celestial light, either as a range attack or a melee attack. Casting as a melee attack allows the user to add their strength modifier to the damage roll.

Celestial Light: Fires a ray of bright silvery light at a target, dealing 1d12 + Charisma modifier radiant damage, alongside forcing the target creature to make a Constitution saving throw (8 + Charisma modifier + Proficiency bonus) or will be blinded for 3 turns or until making a successful save. The blinding feature is on a 6-turn cooldown.

Argetlam can be used to cast a spell of the same name once per day.

Argetlam: Melee attack (spell). Argetlam can be charged to release a massive amount of silvery light on a creature that you can hit with an unarmed strike, (10d8 + Charisma modifier) radiant damage. Upon this attack landing, both the target creature and the user must make a Constitution saving throw (8 + Charisma modifier + Proficiency bonus) or be blinded for either 3 turns or until a successful roll is made
