Ordered Chaos

( Fiendish Codex I: Hordes of the Abyss, p. 86)

[General]

You are an unusually lawful Abyssal heritor.

Prerequisite

base Will save +4, Nonchaotic alignment,

Benefit

Your alignment is not affected by the Abyssal heritor feats you possess. Spells and effects that are keyed to alignment affect you as if you were chaotic, as well as your actual alignment. For example, you become immune to spells such as chaos hammer and word of chaos, you could wield an anarchic weapon without fear of gaining a negative level, and you could take the Primordial Scion feat despite its chaotic alignment prerequisite
