One of the more unique spells taught by followers of the good gods, is a spell
which allows a priest to create a link between himself and another. This link
allows them to share physical pain, which can  sometimes allow the both of
them to survive an ordeal that may be too great for anyone to face alone. This
is a relativly  dangerous spell, since many times both the caster and the
target can be lost if the pain is too great for both of them to survive.
