Amulets of order are relatively rare items that, when worn, will slowly change your alignment toward lawful. Lawful PCs won't notice the effect apart from the slow alignment shift during normal play. Neutral PCs will feel the amulet itch around their neck every time an alignment "stone" is received, with no ill effects. Chaotic PCs will feel burning pain instead of an itch and take damage, which can be lethal - redemption does not come lightly for the wicked. Usually a chaotic PC who wishes to change alignment this way will periodically use herbs or spells to heal himself, or take the amulet off for a while so he will heal naturally. A regenerating item such as the ring of regeneration can be used to counter the periodic damage with its constant healing effect.
