Ashen Lashes

You create two tendrils of magical ash to appear in unoccupied spaces within range. The tendrils can't be targeted with attacks and are immune to damage. 

When you cast this spell and as a bonus action on your subsequent turns, you can command one or more of the tendrils to attack a creature within 10 feet of it. Make a melee spell attack for each tendril using your spellcasting ability modifier. On a hit, a tendril deals 1d4 fire damage to the target. Befor or after an attack, you may move the tandrils up to 10 feet.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you can create one additional tendril for each slot level above 1st.
