Conjure Eldritch Soldier

You create a spectral soldier within range that lasts for the duration or until you cast this spell again. When you cast the spell, you can make a melee spell attack against a creature within 5 feet of the soldier. On a hit, the target takes force damage equal to 1d8 + your spellcasting ability modifier.

As a bonus action on your turn, you can move the soldier up to 20 feet and repeat the attack against a creature within 5 feet of it.

The soldier can take whatever form you choose. The wizard can create the aesthetic look of the soldier but it is always transparent and spectral in nature.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d8 for every two slot levels above 2nd.
