Dysfunctional Rules X: I Cast Comprehend Rules

[St Fan]

Not a big one, but still made me blink:

Light of Faith
Abjuration [Good]
Level: Cleric 2
[...]

This spell grants you a sacred (if you are good or neutral) or profane (if you are evil) bonus equal to one-half your divine caster level (maximum +5) on your next turning check.

This spell has the Good descriptor. Thus no evil Cleric can cast it. Thus there is no way to gain a profane bonus with it, despite what it says.
