Trickster Knight's Spear

Choose one creature you can see within range, all creatures within 5 feet of the target are also considered targets but get advantage on the save (this is only true until the spell levels up). The target must succeed on a Dexterity saving throw or take 2d4 necrotic damage.

This spell’s damage increases by double when you reach 5th level (4d4), 11th level (8d4), and 17th level (16d4).

The range doubles as well after 5th level.
