Silver Spark

You have overcome an evil within yourself. The Silver Flame has recognized this, and has granted you a spark of power. Once per long rest you can do each of the following:

Argent Armament. As an action, you can touch a weapon and give it the silvered property and it becomes a +1 weapon. 

Gallant Guardian. As a reaction, when an ally within 5 feet of you fails a saving throw, you can envelope them in silver fire to protect them. The ally can reroll that saving throw. 

Silver Scourge. As a bonus action, you ignite your weapon with silver fire. For the next minute, your weapon attacks deal an extra 1d4 radiant damage, reduce your target’s movement speed by 5 feet, and once per turn you, or an ally within 10 feet of you is healed 2d4 hit points.
