Umbral Blade

1st-level illusion

Casting Time:1 action

Components:V, S, M (a pair of miniature swords)

Range:Touch

Duration:Concentration, up to 1 minute

Classes: sorcerer, warlock, wizard

You touch one weapon, imbuing it with subtle and deadly magic. A shadowy afterimage trails behind the targeted weapon, potentially damaging foes even when the weapon misses. For the duration, when the wielder of the weapon uses the Attack action, they gain an additional single attack with it. On a hit, instead of its usual damage, the shadowy afterimage deals 2d6 necrotic damage.

At Higher Levels: When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for every two slot levels above 1st.
