Gnome Tremble (5e Equipment)
From D&D Wiki
Weapon (katana), very rare (requires attunement)
This katana was made from the fangs and claws of a powerful spirits which was only thought to be a myth. Legend say that a piece of gnome soul was infuesd with the sword giving it the power of earth.
Titan Earthshaker: As an action, you may drive the sword into the ground, shaking all creatures and structures in contact with the ground within 60 feet of you. If the ground is made of earth or stone, the area becomes difficult terrain within the range. Each creature on the ground in the area must make a DC 17 Dexterity saving throw. On successful save, the creature takes half of the 5d10 bludgeoning damage, and is not knocked prone.
This effect may be used two times, and the katana regains all uses of this effect at dawn.
