Mob Slayer

You have mastered melee combat against large hordes of enemies. You gain the following benefits:

• Increase your Strength or Dexterity score by 1, to maximum of 20.
• If you reduce a creature to 0 hit points with a melee attack, you can make one additional melee weapon attack against a target within your reach. If the attack hits, the target takes damage equal to the excess damage from the creature you reduced to 0 hit points. This can be used more than once per turn provided there are enough targets within your reach.
