@el_condoroDoes Blindsight allow you to automatically see creatures using obscurement to hide in order to cause them to lose hidden? An undistracted creature with blindsight does typically notice creatures who aren't behind cover.

@wax_eaglecan you target a creature who is obscured but not hidden? More precisely, is hidden the only way to conceal position? Being hidden is the by-the-book way to conceal your position. The DM may decide that other methods can also conceal it.
