tier 3 : King Mog XIII
Don't forget Elder primal Belias "egi" from the SMN quests.

I'd also like to point out that King Moggle Mog isn't a primal at all.

So far the primal battles have focused on four or eight adventurers battling against a primal. However, Good King Moggle Mog XII looks to even the score as the battle will pit 8 adventurers against 8 enemies at once!
(Though, keep in mind that Good King Moggle Mog isn't a primal!)
