Terrorasque Double-Bladed Scimitars (Rare)

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.

From the fossilised teeth of a tar-rasque is extracted the magic of rage and ferocity. Upon attuning to this weapon, you gain the ability to unleash terrifyingly monstrous roars and swing the enormous, bone-handled blade with astounding aggression. You gain a +1 bonus to attack and damage rolls you make with this magic weapon. This weapon has 5 charges and regains 1d4 + 1 charges daily at dawn.

Ferocious Blow: As an action, you can expend 1 charge to call upon the spirit of the tar-rasque and make a mighty swing with this weapon. If the attack hits, roll four times as many damage dice for the weapon as normal for this attack. This dice multiplication does not affect additional damage from abilities such as smite or sneak attack, and is unaffected by critical hits. If the attack misses, you fall prone and your speed is reduced to 0 feet until the start of your next turn.

Terrorise: As a bonus action, or as part of the bonus action you use to activate the Rage class feature, you can brandish the terrorasque, amplifying your yell with that of a tar-rasque's. Each hostile creature within 60 feet of you that can hear you must succeed on a DC 15 Wisdom saving throw or be frightened of you for 1 minute. An affected creature can repeat the saving throw at the end of each of its turns, ending the effect for itself on a success. After you use this property, you can't do so again for 1 hour.

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.
