Banshee Blade

This sword sings an inspiring song when wielded that only its user can hear. You gain a +1 bonus to attack and damage rolls made with this magic sword. As a bonus action, you can make the empowered banshee blade either sing or shriek.

• When the empowered banshee blade sings, you select up to four creatures you can see, which can include yourself. The selected creatures add a 1d4 to all their attack rolls when they are within 10 feet of the banshee blade. You roll the d4 each time a selected creature attacks.
• When the empowered banshee blade shrieks, you select up to four creatures you can see. The selected creatures subtract a 1d4 to all their attack rolls when they are within 10 feet of the banshee blade. You reroll the d4 each time a selected creature attacks.

While the banshee blade is singing or shrieking, you have disadvantage on stealth checks. The banshee blade sings or shrieks for 4 turns. Once the banshee blade has sung or shrieked, it can’t do so again until you finish a long rest.

Proficiency with a Rapier allows you to add your proficiency bonus to the attack roll for any attack you make with it.

Notes: Bonus: Magic, Damage, Buff, Debuff, Combat, Finesse, Vex
