Ratbite

These pungent weapons are made of leather of dubious origin with clumps of fur still attached. The leather grip fits snugly over the knuckles, with rat teeth and bits of bone sticking out the outward facing side. It gives off an unpleasant odor. You gain a +3 bonus to attack rolls and damage rolls made with these magic weapons. While you are attuned to these weapons, you have Immunity to magical contagions. Any creature who takes damage from this weapon must succeed on a DC 1 Constitution saving throw or contract Sewer Plague. When you score a Critical Hit against a creature with these magic weapons, it takes an extra 2d4 Necrotic damage and has Disadvantage on saving throws against magical contagions for seven days.

Vex (Mastery): 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.

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: A light weapon is small and easy to handle, making it ideal for use when fighting with two weapons.
