One of the interesting parts of the owl is its flyby ability
Flyby: The owl doesn't provoke Opportunity Attacks when it flies out of an enemy's reach.
With this ability, could a druid wildshape into an owl (lets assume circle of the moon bonus action transformation for the sake of action economy) and go for a direct attack against the eyes, blinding the enemy? And if so, what's stopping the druid from abusing this ability and making every enemy they face blind with no opportunity attacks?
Considering how crippling a permanent blind condition is…
A blinded creature can’t see and automatically fails any ability check that requires sight.
Attack rolls against the creature have advantage, and the creature’s Attack rolls have disadvantage.
This just seems like a really powerful strategy and I can't see any downsides to just spamming this strategy, are there any drawn backs I'm not seeing (pardon the pun)? Or are owls just straight up unable to be that specific with there attacks?
To be specific, this question is not called-shots or "could that attack work?", but rather preventing abuse of the ability or "what is the counter towards the attack?" Without an attack of opportunity I don't see how a creature could prevent this from happen or counter the attack with an attack of its own, it just seems like a free blind condition on anyone you chose with no consequences.
