Adran's Blade Binding

You tense your grasp around a dagger, shortsword, scimitar, rapier, or longsword in your hand, imbuing with your arcane mark. While this spell is active, you gain proficiency in that weapon and may use your Spellcasting Modifier for damage and to hit rolls. You may use this blade as your Arcane Focus. This spell ends when you let go of the blade.

When you cast this spell using a spell slot of 2nd level or higher, you may cast this spell as a bonus action.
