Do we have a list of the places where you can snipe at 20 range?

[ciox]

So we all know that sniping beyond range 13 is usually not possible due to the sight range limitation on the player, but you can sometimes do it if a cutscene gave you vision, for instance when going to Deep Caverns and fighting the final boss or the mushroom boss.

What are all of the cases in the game where you can do this?

No, but honestly each 2 Per points from 5 and above should grant +1 to sight range. YA HEAR ME STYG!?!?!?

You can shoot objects, some turrets, and the final boss from beyond the sight range; anything that is still visible for you to click on.  You can even target regular enemies from afar if you rightclick them, move away, and target their picture before it disappears.

If you click on the portrait you can snipe targets out of view.
