Kime Strike

You've learned to strike critical points on your enemies, disrupting their Chi and causing massive damage. You gain the following benefits:

• On your turn, when you score a critical hit or reduce a creature to 0 hit points with a monk weapon or open hand strike, you can make one extra attack before the beginning of your next turn.
• Before you make a melee attack with a monk weapon or open hand strike, you can choose to take a -5 penalty to the attack roll. If the attack hits, you add +10 to the attack's damage
