You are an expert when it comes to daggers, years of training have given you the following benefits:

• Flurry of Stabs: You are able to strike in quick succession. If you are holding a dagger or dagger-like weapon when you take the attack action, you can choose to take a -2 to hit rolls this round and make an extra attack.
• Knife Tosser: You know a technique that makes you a better at throwing knives. Daggers and dagger-like weapons have a range of 30/75.
• Throat Slitter: Sssssht! It will all be over soon. If you make a successful attack from hiding with a dagger or dagger-like weapon, and the attack would kill or knock the opponent unconscious, you may have the action produce no more noise than a whisper.
