Gotcha!

You can't expect people to move through the underground at the pace of a snail, constantly stopping and observing if there's any chance for you to die right now if you get cheapshotted by an off-screen medusa. That's not fair and you know it.4. You can't prepare for this.
You can, actually, by thinking twice about jumping off that cliff or dawdling over a pit of lava. Even if they make medusa have line of sight you are still going to have to sit there and wait for a chance to attack, so you are waiting anyway.
