I tested the become pretender effect, not really game breaking or special. Units made pretender with a "join pantheon" ritual just gain the pretender tag and hp etc... bonus in friendly dominion, but don't spread dominion and are not callable back by priests if killed (I have still to test if they gain immunity to some spells like charm/enslave like a true pretender).

The become prophet effect would be a little more powerful (as prophet have att/def bonuses pretender don't have) but rituals with this effect do nothing (the effect strangely works if cast in battle and part of a spell combining it with another buff ; the target then permanently become a non-dominion-spreading prophet)
