Guerilla Warfare

You have a wealth of experience and training at striking from the shadows. This particular set of skills gives you the following benefits.

• You roll one extra damage die when you make a melee weapon attack with advantage against an unsuspecting target.
• You do not suffer disadvantage to your Dexterity (Stealth) checks from wearing heavy armors.

Additionally, you learn the Knockout maneuver. When you make a melee weapon attack with advantage against an unsuspecting target, you can forgo the damage roll and have the target make a Constitution Saving Throw with disadvantage against a DC equal to (10 + your proficiency bonus). A failed save knocks the target out and makes them stunned. The target can attempt the save again at the end of their next turn. This maneuver is completely silent.

You can use this feature a number of times equal to half your proficiency bonus between long rests.
