Greatsword of Grass

This magic weapon has 7 charges. While holding it, you can use a bonus action and expend 1 charge to conjure a thick patch of shrubs, grasses, aboveground roots, and even small saplings in a 10-foot radius. The area becomes difficult terrain, and the foliage is thick enough to provide cover against ranged attacks. The growth is permanent unless you speak the command word again. The weapon regains all expended charges after a short or long rest.

Heavy: Creatures that are Small or Tiny have disadvantage on attack rolls with heavy weapons. A heavy weapon's size and bulk make it too large for a Small or Tiny creature to use effectively.

Two-Handed: This weapon requires two hands when you attack with it.
