You weave illusion magic into your arrow, causing it to occlude your foe’s vision with shadows. The creature hit by the arrow takes an extra 2d6 psychic damage, and it must succeed on a Wisdom saving throw or be unable to see anything farther than 5 feet away until the start of your next turn.
A creature with blindsight can perceive its surroundings without relying on sight, within a specific radius.
If a creature with blindsight (like a Flying Sword) fails its saving throw against an arcane archer’s Shadow Arrow, is its ability to perceive enemies via blindsight restricted? Would creatures with truesight or tremorsense be handled the same way?
It seems to me that this is fairly straightforward, but upon reading this question about opportunity attacks, there seem to be cases where the word “see” is used more generically as all forms of perception.
