K.I.S.S. Master

Keep It Simple Stupid. Your motto in life. Through thorough training you've learned to find the simple faults in the enemies styles, tactics, and armor. While using Finesse weapons you strike these faults with uncanny speed and  precision control. You gain the following benefits:

• On your turn, when you score a critical hit with a finesse melee weapon you cause the creature to become wounded making it have disadvantage on attacks untill the end of it's next turn.
• Before you make a melee attack with a finesse weapon that you are proficient with, you can choose to take a -5 penalty to the attack roll. If the attack hits, you add +10 to the attack's damage.
