If cast without an existing blade, the spell evokes an earthen blade in the hand of the magic user. The blade is similar in size and shape to a scimitar, and it lasts for the duration. If you let go of the blade, it disappears, but you can evoke the blade again as a bonus action.
If cast on an existing blade via touch, the spell causes earthen elements to congeal on the existing blade, creating a sharper edge and a heavier blow.
You can use your action to make a melee spell attack with the fiery blade. On a hit with the entirely earthen blade, the target takes 3d6 bludgeoning damage. It takes an additional 1d6 if cast on an existing weapon. On a successful hit, the target must also succeed on a Strength Save or be grappled in place to the earth. Creatures size huge or larger automatically save.
At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d6 for every two slot levels above 2nd.
