a weapon combined from the yin sickle and the yang sickle. The two can combine and form into a stronger weapon which is the yin-yang scythe sickle. It grows in power and uses the necrotic and radiant energy of the blades combining them into a pure attack. 

The double-bladed scimitar is the signature weapon of Valenar elves. A haft of fine wood supports a long, curving blade on either end. Forged with techniques honed over centuries, these blades are strong, sharp, and remarkably light. Each scimitar is a masterpiece, and as a result the double-bladed scimitar is an expensive weapon (100 gp) — few though ever have the opportunity to purchase one. A Valenar blade in the hands of a non-elf is generally assumed to have been stolen or looted from a fallen foe, and a Valenar elf might feel entitled to demand its return or challenge the bearer to prove they’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.
