Cloak of chaos

Charm person was an abjuration spell that granted magical armor and magical resistance.

Effect
A random pattern of color surrounded the subjects, protecting them from attacks, granting them resistance to spells cast by lawful creatures, and confusing lawful creatures when they struck the subjects. This abjuration had four effects:

First, the warded creatures gained magical armor and resistance. Unlike protection from law, this benefit applied against all attacks, not just against attacks by lawful creatures.

Second, the warded creatures gained spell resistance against lawful spells and spells cast by lawful creatures.

Third, the abjuration blocked possession and mental influence, just as protection from law did.

Finally, if a lawful creature succeeded with a melee attack against a warded creature, the offending attacker was momentarily confused unless he or she had the willpower to prevent it.

Focus
A tiny reliquary containing some sacred relic, such as a scrap of parchment from a chaotic text. The reliquary cost at least 500 gp.
