Stealth Fighter

You have become so proficient in stealthy attacks that you have managed to master the art of getting the drop on your enemies. Your stealthy fighting style grants you the following benefits.

• You can now use your dexterity or strength modifier for any one-handed weapon, not just finesse. 
• You gain Expertise in stealth if you didn't have it already. 
• When you get a critical hit during a sneak attack, your enemy falls prone if your sneak attack dealt bludgeoning damage. 
• Sneak attack damage goes up by 1d6.
