Flame Tongue Shortsword 2024
Weapon, rare, (requires attunement)
While holding this magic weapon, you can take a Bonus Action and use a command word to cause flames to engulf the damage-dealing part of the weapon. These flames shed Bright Light in a 40 foot radius and Dim Light for an additional 40 feet. While the weapon is ablaze, it deals an extra 2d6 Fire damage on a hit. The flames last until you take a Bonus Action to issue the command again or until you drop, stow, or sheathe the weapon.
Properties
Finesse
When making an attack with a Finesse weapon, use your choice of your Strength or Dexterity modifier for the attack and damage rolls. You must use the same modifier for both rolls.
Light
When you take the Attack action on your turn and attack with a Light weapon, you can make one extra attack as a Bonus Action later on the same turn. That extra attack must be made with a different Light weapon, and you don't add your ability modifier to the extra attack's damage unless that modifier is negative.
VexMastery
If you hit a creature with this weapon and deal damage to the creature, you have Advantage on your next attack roll against that creature before the end of your next turn.
