The Scarecrow

Far in the distance, the town's church bell tolls midnight. You stand in the silent corn fields, the whispering of the plants beckoning you forward. You cannot resist, delving deep in the identical rows of hushed straw and corn. When you can no longer see the town behind you, you come across a pile of cloth and straw in the shape of man slung up on a pole. The whispering of the fields suddenly comes from the lone scarecrow, and two burning eyes open. It whispers you a deal, and you accept.

 

You have made a deal with a benevolent construct, one that gives you the ability to hide in plain sight and exhume an aura of fear. Eventually, you can be a sleepless sentinel, watching over your party for ever and ever.

Power Of The Construct

Starting at first level, you gain part of the ability to hide yourself in plain sight, just as your patron can. You gain proficiency in the disguise kit, and investigation checks made to find you while disguised have disadvantage. Additionally, you gain advantage on checks made to ward off the frightened condition. 

Finally, difficult terrain in fields or farms no longer costs you extra movement. 

Where Did That Statue Come From?

Starting at 6th level, you can disconcertingly appear in places you should not be. While you are hidden in plain sight using your disguise kit, you can teleport up to 66 feet to a place that you can see as a bonus action. Investigation checks made to find you after teleporting have disadvantage. Additionally, when an investigation checks allows someone to spot you, you can force them to make a Wisdom saving throw against your spell save DC. On a failure, the target is frightened of you until the end of your next turn. 

 

You can use this ability as many times as half your Charisma modifier rounded up per long rest. 

You Can't See Me

Starting at 10th level, you can add your Charisma modifier to stealth checks, as your confidence in hiding in plain sight grows. Your physicality also begins to change as your Patron continues to influence you. You gain resistance to poison damage, and you are immune to being frightened. 

Field Sentinel

Starting at 14th level, you have completed your transformation. You are now a construct (if you were not one already) and a humanoid, so you can be affected by spells targeting constructs or humanoids. In addition, when you are hiding in plain sight, you no longer need air, food, water, or sleep. 

 

Also, the constraints of age no longer has a hold of you. You no longer age ad magic that would age you no longer effect you.
