Manual of Bodily Health: As with all magical writings of this nature, the
metal-bound Manual of Bodily Health appears to be an arcane, rare, but
non-magical book. If a detect magic spell is cast upon it, the manual’ will
radiate an aura of magic. Any single character who reads the work (24
hours of time over 3-5 days) will know how to increase his or her constitution
by 1 point by following a regimen of special dietary intake and
breathing exercises over a 1 month period. The book disappears immediately
upon completion of its contents. The 1 point of constitution is
gained only after the prescribed regimen is followed. In 3 months the
knowledge of the secrets to bodily health will be forgotten. The knowledge
cannot be articulated or recorded by the reader. The manual will not
be useful to any character a second time, nor will other than a single
character be able to benefit from it.
