Prerequisite: Level 4 rogue
- You develop blindsight up to a range of 10 feet (extended to 20 at level 14).
- Your blindsight can only work in a setting where your character can use their other senses like hearing or smell.
- You gain advantage on wisdom (perception) checks that rely on hearing or smelling.

I think the level 14 benefit was fine as it was. This should've been a more powerful feat in other ways, instead of trying to increase an ability which is already almost as powerful and which is high level for a reason, I think.
