Arcane Reach

You brandish the weapon used in the spell’s casting and create a force field that acts as an extension of the weapon. Until the start of your next turn, your reach with the weapon increases by 5 feet. As part of the action used to cast this spell, you can make a melee weapon attack against one creature within reach.

This spell's extended reach increases by 5 feet when you reach 5th level (10 feet), 11th level (15 feet), and 17th level (20 feet).
