Cleaving Liquid Blade

You brandish the weapon used in the spell’s casting, infusing it with elemental water, causing high-pressure ribbons of water to extend the weapon’s edge or point, and granting your weapon a temporary reach of 15ft for this attack. Make a melee attack with the weapon against one creature within range, and on a hit, the target suffers the weapon attack’s normal effects, as well as an additional 1d6 weapon damage from the increased momentum.

This spell’s damage increases when you reach certain levels. At 5th level, the attack deals an extra 1d6 (2d6) weapon damage to the target on a hit, and further increases by an additional 1d6 at 11th level (3d6) and 17th level (4d6).
