Tremorsense kind of helps with that too.
Not quite.

Invisibility grants advantage on attacks for the invisible one, and disadvantage for anyone trying to attack them, regardless of how stealthy the invisible one is. As in, even if they're a knight in full plate singing war songs at the top of their lungs.

Blind Fighting let you ignore that, so long as they're in the area around you.
