Azrael's Black Flame Blade

This spell may only be cast using a Lantern of Loss as the focus. You brandish the weapon used in the spell’s casting and make a melee attack with it against one creature within 5 feet of you. On a hit, the target suffers the weapon attack’s normal effects, takes 1d8 force damage (increasing to 2d8 at 5th level, 3d8 at 11th, and 4d8 at 17th), and receives the Devoid status effect until the start of your next turn as the black flame leaps from the weapon onto the creature. A creature subjected to the devoid status effect is left devoid of the weave, rendering them incapable of casting spells that use Mystra's Weave for the duration. Additionally, when the target is wreathed in Azrael's Black Flame, it gains resistance to magic damage of any type other than psychic cast with spells using Mystra's Weave, and can pass through magical barriers as if they were not there. You may alternatively use this spell to strike a creature's corpse who has been dead no longer than a minute to purify its soul and channel it into a lantern of loss.
