Cloak of chaos

Charm person is an abjuration spell that grants +4 AC, +4 resistance, and spell resistance 25 against lawful spells.

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

First, the warded creatures gain a +4 deflection bonus to AC and a +4 resistance bonus to saves. Unlike protection from law, this benefit applies against all attacks, not just against attacks by lawful creatures.

Second, the warded creatures gain SR 25 against lawful spells and spells cast by lawful creatures.

Third, the abjuration blocks possession and mental influence, just as protection from law does.

Finally, if a lawful creature succeeds with a melee attack against a warded creature, the offending attacker is confused for 1 round (Will save negates, as confusion, but against the save DC of cloak of chaos).

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