Clerics currently gain an aluignment aura for the purposes of Detect Alignment spells that is equivilent to that of an outsider of HD equal to their cleric level.
What would happen if a cleric simply gained an alignment subtype instead? Besides making Align Weapon less useful?
I'm not sure if this would be a good idea or not, because I'm not sure what all the implications would be. Ideas?
Combined with the idea here, in which an alignment subtype would move your detection up one category, I think that granting Clerics and Paladins alignment subtypes is a good option.
It would allow the 'cleric' line to be removed from the table, makes Clerics vulnerable to alignment-based attacks based on their deity's alignment, makes Paladins capable of innately battling fiends without align weapon or smiting, and just generally seems elegant.
