You cause a tendril of undeath to sprout out of the ground at a point you can see within range. All creatures within 5 feet of the tendril must make a Dexterity saving throw or take 1d6 necrotic damage.

This spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
