This double-bladed scimitar was specially enchanted by Elyian, a simulacrum turned true sentient. Much like it's owner, its blades are unusually cold to touch, and are etched with alien teal runes on both sides. Its long, dark hilt is made out of twin scimitars attached from their silver pommels, which flash with a red light when wielded by a creature of evil alignment, or purple when wielded by a creature of good alignment.
This weapon emanates a freezing aura around it. When held, the wielder takes 1d8 cold damage at the start of their turn if they are not resistant to cold damage.
Magical. You have +3 to attack and damage rolls made with this magic weapon. Furthermore, all damage made through this weapon is automatically converted into cold damage.
Special. Once per day, the wielder can cast Investiture of Ice spell through this weapon. When used, this weapon loses both its magical properties as well as this feature, which are both gained at the start of next dawn.
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.
