Master Assassin

This feat correlates with the Superior Hidden Blades magic item and the Assassin's Apprentice and Advanced Assassin's Apprentice feat.

You have risen to the second highest rank among the assassins. You are granted with mystical powers only few receive every century. You gain the following benefits:

• You gain resistance to all non-magical bludgeoning, piercing, and slashing damage.
• You gain an additional 60ft. of Blindsight (uncapped).
• You can cast Find Familiar. Your familiar will take the form of any small bird you like, and use the statblock of your choice between for a raven or owl (you can make this choice each time you recast this spell using this feature).

• If you surprise a creature and hit it with an attack on your first turn in combat, the attack deals an extra 2d6 damage to it. You can use this trait only once per combat.
