The Shackled City
Fiendslayer Crystal, Lesser
This perfect crystal sphere emits a faint white glow.
A fiendslayer crystal helps you fight creatures infused with evil.
The weapon with this crystal attached deals an extra 1d6 points of damage to evil outsiders and it is treated as good-aligned for the purpose of overcoming damage reduction.
Any evil creature grasping a weapon that bears a fiendslayer crystal gains one negative level, which remains as long as it holds the weapon and disappears when the weapon is no longer wielded. This negative level never results in actual level loss, but it cannot be overcome in any way (including restoration spells) while the weapon is wielded.
