Shadow Infiltrator

Having adeptly honed the skill of concealing oneself within the midst of the ordinary, you've acquired a profound mastery in the art of remaining unnoticed, seamlessly blending into the tapestry of everyday life with an uncanny ability to elude detection and observation.

Blending in

Starting at 3rd level, you can use a Dexterity (Stealth) check, to hide in the crowd adding +5 to stealth checks

Opportunist

At 3rd level, you can scan the room within a 30-foot radius for potential weapons, tools, or people. You can see the damage items can deal and gain information about the properties of items. Additionally, you can tune out crowd voices to listen to one conversation within the same range.

Stalking

Starting at 9th level, if you watch a target within 30 feet for 1 minute, you can choose between gaining information about their HP and AC, their items, or having a guaranteed crit if you hit him before they can hit you. After stalking, you can spot your target easily in a crowd.

Chameleon

Starting at 13th level, if you wear a disguise/uniform, if you are not within 5 ft of someone or are in someone's vision for 1 minute or longer, you wont be seen.

Anatomy expertise

Starting at 17th level, you can see the weak spots on people. Once per short rest, you can use this knowledge to gain advantage on attack rolls against a chosen target for 1 minute.
