So for Lore we get: Ifrit, Garuda, Leviathan, and Shiva.

That leaves: Titan, Ramuh, Moggle Mog, Bismark, and Ravana as far as the story ones are concerned. Presuming that Moggle Mog will be skipped, that gives us another four primal armors for the next Tombstones if they so wish.

And I really want my Bettleborg armor.
