Bladeworks

For the duration of the spell, the caster may fire, at high velocity, four objects stored in a demiplane, instance of Leomunds Tiny Chest, personal void, or other bag of holding/extraplanar space they have access to. A Bladeworks attack takes a combined action and bonus action. Weapons fired in this way attack as a ranged spell, applying the spell attack modifier of the caster. On hit, the weapon rolls for damage normally and adds an extra 1 damage to the total. Non-weapons fired by the spell attack in the same way, but damage is dealt as 1d20 halved +1 and would apply effects logical to the item.

At higher levels. When you cast this spell using a spell slot of 7th level, the number of weapons that can be fired off increases by one per level.
