Twilight Blade

You weave together threads of shadow and the blessed energy provided by Ellagywn to create a sword of solidified twilight in your hand. This magic sword lasts until the spell ends. It counts as a any melee finesse weapon with which you are proficient.

When you cast this spell, you can choose radiant, necrotic, or psychic damage type; the weapon deals 3d8 on a hit and has the finesse property and the light property.

In addition, when you use the sword to attack a target that is in dim light or darkness, you make the attack roll with advantage.

Once per turn as a free action, you can extinguish a single light source within 60 ft of the weapon.

While the spell persists, you can use a bonus action to cause the sword to reappear in your hand.

At Higher Levels. When you cast it using a 5th- or 6th-level spell slot, the damage increases to 4d8. When you cast it using a spell slot of 7th level or higher, the damage increases to 5d8.
