Divine Spirit aptitude. At high levels one is treated as a mixed race of a Divine Spirit, and the level declines when the Heroic Spirit's own rank as a Monster, Demonic Beast raises. It can also decrease due one's dislike for the gods. It also has an effect which reduces special defensive values called "purge defense" in proportion to the Divinity's Rank. It can break through Skills such as Protection of the Faith. [/quote] 

It doesn't particularly do anything, but it is still a skill that those of the demigod category tend to have.
