Rangers can't deal damage on Graveling Burrows in AC dungeon explore mode
I’ve noticed that objects in general often can’t be hit with projectiles (sometimes says out of range, sometimes says obstructed)
melee are affected as well but instead they miss unless attacked while moving, sometimes they don’t have this issue if they find the right spot to attack from
seems none of these occur with some specific objects like the very first burrow you encounter in AC explorable mode so I am lead to believe that it’s a matter of where the actual location (or “hit box” if you prefer) of the object is configured to be or something like that
