Serpents
Serpents are heavily armored and entirely invulnerable to Beethro's
sword. The only way to destroy a serpent is to lead it into a
dead end. Of course, if Beethro walks into the dead end in order
to lead the serpent, it will be a dead end for him too. A serpent
cannot move diagonally. Unlike other monsters, a serpent will
never walk onto a force arrow even if it is going in its direction.
The serpent will generally move towards Beethro but
not always. This is not random--you will want to understand the
serpent's movement behavior to solve different rooms.
