I guess what I was trying say was tempering seems to have had rules up to about ramuh and then not so much.
The primals became way more complex and I think tempering wasn't really needed since the later prinals worked differently. I don't think the heretics, mog guard, or heavens ward were tempered, just remained loyal. But this is just another example of how it's not very clear and doesn't seem to be consistent after the first elemental primals.
