Been watching some Daredevil. Let’s make some ideas for that.
See the Unseen
You can see what no one else can see. Gain the following:
- Gain proficiency in perception or double your proficiency bonus to perception.
- Gain blindsight 30 feet.
Thoughts?

Too powerful. Blindsight should be no more than what warlocks can gain which is 10ft. It might be better to make it 5ft so the warlock class is more powerful but still useable, at least in melee.
That seems fair. I agree with it being 5 feet. You fighter is powerful, but not as supernatural. Also, this would still be every rogues best friend.
