Double-Bladed Scimitar 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.

The double scimitar is the signature weapon of Valenar elves. A haft of fine wood supports a long blade on either end. Forged with techniques honed over tens of thousands of years, these blades are strong, sharp, and remarkably light. Each scimitar is a masterpiece, and as a result the double scimitar is an expensive weapon, but few people ever have an opportunity to purchase one. If you're an elf, your blade could have a long and storied history. If you're not an elf, you might have stolen the weapon from a fallen foe or received it from a dying Valenar ally. If you work with your DM to create the story behind your double scimitar, you can start with the weapon at 1st level in place of a martial weapon normally granted by your class. However, it can be dangerous for a non-elf to carry a double scimitar. Valenar may demand its return or challenge you to prove that you're worthy to wield it.

Special: If you attack with a double-bladed scimitar as part of the Attack action on your turn, you can use a bonus action immediately after to make a melee attack with it. This attack deals 1d4 slashing damage on a hit, instead of 2d4.

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