Crossing Slashes

A sword-aspected spell of Eirdmos's Battlemages.

You lunge forward, slashing an X of sword energy with both hands. Make four melee spell attacks against creatures of your choice within a 10-foot cube centered on a point within range. On a hit, an attack deals 1d6 force damage plus 1d6 slashing damage. As a bonus action, you can choose to charge the spell, making a fifth attack that, on a hit, deals 1d8 force damage plus 1d8 slashing damage. Alternatively, you can input additional commands as a bonus action, making two additional attacks that each deal 1d4 slashing damage plus 1d4 force damage.

At Higher Levels. For each spell slot level above 1st, make an additional attack.
