Sunblade

Using a bonus action causes a blade of pure radiance to spring forth from this weapon's silver hilt. While the blade exists, it has the finesse property, and it deals radiant damage instead of slashing damage. Also, the wielder gains a +2 to attack and damage rolls with
the Sunblade, and undead foes take an extra
1d8 radiant damage. The Sunblade's blade emits light in a fifteen foot radius
