Dagger Master

You know the workings of a dagger, from the very point down to the end of the hilt. You gain the following benefits:

• Any attack that hits a surprised creature with a dagger is considered an automatic critical hit.
• You gain advantage on Dexterity (Sleight of Hand) checks in order to conceal your dagger.
• You may conceal your dagger on your body. Any creature attempting to search you for weapons does so at
  disadvantage in order to find this weapon.
