Grim Harvester

You gain a +1 bonus to attack rolls and damage rolls made with this magic weapon. This weapon has the Finesse property. On a hit, the sickle deals an extra 1d6 Necrotic damage. In addition, by using a Bonus Action, you can awaken the sinister energies that dwell within this weapon for 1 minute. For the duration, wounds inflicted by this weapon harvest the essence of the target's soul, reducing its Hit Point maximum by an amount equal to the damage dealt. This reduction lasts until the target finishes a Long Rest. The target dies if this property reduces its Hit Point maximum to 0. Once this property is used, it can't be used again until the next dusk.

Nick (Mastery): When you make the extra attack of the Light property, you can make it as part of the Attack action in· stead of as a Bonus Action. You can make this extra attack only once per turn.

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. For example, you can attack with a Shortsword in one hand and a Dagger in the other using the Attack action and a Bonus Action, but you don't add your Strength or Dexterity modifier to the damage roll of the Bonus Action unless that modifier is negative.

Finesse: When making an attack with a finesse weapon, you use your choice of your Strength or Dexterity modifier for the attack and damage rolls. You must use the same modifier for both rolls.
