4. MAGNETIC EFFECTS OF LODESTONE

An occasional feature of the underground environment that
can cause consternation and serious problems for a PC character
is the magnetic field created by a band of lodestone.
Magnetism affects characters cloaked in iron armor, and can
impede combat when iron weapons are used.

Lodestone in its more innocuous form is encountered frequently
in areas containing iron ore. In this common form, the
magnetic pull is barely strong enough to be noticed, and certainly
cannot impede a character’s movement or combat.
Deep beneath the earth, however, concentrated ores of iron
and other minerals have formed regions of massively powerful
magnetic rock. The magnetic attraction of such rock can be
detected by a character who passes a WIS Check when still
120 feet distant from the lodestone. This initial detection is manifested
by nothing more than a slight tug on all iron possessions.
The lodestone’s effects become obvious to any characters
moving within 90 feet. The force upon metal objects, while definitely
noticeable, is still not capable of pulling a character against
his will.

A character who comes within 30 feet of such a powerful lodestone
becomes threatened. Iron objects hanging on the character
are pulled toward the lodestone with a force that can snap a
thin leather strap. The character must make a Strength Check for
all hand-held objects containing iron. If the character is wearing
iron armor, he must make an additional Strength Check or be
pulled 10 feet closer to the lodestone.

If the Strength Check is successful, the character retains hold
of the item, or holds his ground and does not get pulled toward
the stone. No further checks are required as long as the character
does not move closer to the stone.
When the stone is approached, whether voluntarily or not, the
Strength Checks must be repeated each 10 feet. A character suffers
a -2 penalty to his Strength when 20 feet away, and a -4 penalty
if only 10 feet away.

Removing any iron object stuck to the lodestone requires a
Strength Check with a-6 modifier. If the check fails, the character
is forever unable to remove the object. These lodestones lose all
their powers if removed from their natural settings.
