Couldn't find answers for these on the wiki.
1. I've read that the main basic stats (STR, DEX, INT, etc.) are assigned to elements, do the avatars reflect this as well?
2. In addition to the above, do avatars differ from each other stat wise and if so, what are the differences?
3. I've noticed that Carbuncle gets an Auto-Regen ability do other avatars get passive traits as well? If so, what are they and at what level?
Finally, I've managed to get it so that Carbuncle's perpetuation cost was 0 from levels 25 to 29, are there any other ways to get any avatars down to 0 perpetuation for levels 30-50?
Any extra info or advice is also appreciated.
