Hyperdense Greatsword (5e Equipment)
From D&D Wiki
Martial Melee Weapons
A greatsword that has been made from collapsed matter a thousand times more dense than steel.
Hyperdense: Hyperdense weapons are so unfathomably heavy that they need a built-in antigravity device just so it's practically possible to lift them off the ground, let alone wield them with any effectiveness. The antigrav runs for 24 hours on one energy cell, and while it's on only 6 lb. of the sword's weight counts towards your encumbrance. However, it still strikes with the force of its full weight.
