Alignment and aligned damage

The aligned damage of a creature not from the material plane works against everybody native to the material plane except those with a noticeable aura of the same alignment.

For example, the evil damage of a demon damages a good angel as well as every low-level human whether good, neutral or evil.

Faint alignment auras are undetectable.

Alignment auras are one step stronger than normal for all spellcasters whose magic power comes from a patron. Any tradition, any patron - not just divine casters, and not just patron deities.

''This means that evil criminals of less than 11th level are normally not detectable as such. It does mean occult sorcerers (for example) register just as strongly as divine clerics, undead and demons.''
