The Master Seal will promote anyone but the Lords in this game. You get one in the Ch15 village. (This is unlike the Earth Seal of FE7, where it wouldn't promote Thieves or Pirates.)
Alternatively, you could have bought one in Ch14's Secret Shop, and then sold the aforementioned Master Seal. But that's not really important, so don't worry too much about it. --- HE LOOOOOOOOOOOOOOOOOOOOOOVES THAT MEAT! ~line from "Butcher Pete," a song in Fallout 3
In FE7, the Earth Seal wouldn't promote Lords, Thieves or Pirates because they required unique, expensive promotion items.
In FE8, only the Lords require unique promotion items. The Master Seal can promote anything other than the Lords. --- Life isn't fair. If it was, we'd all be dead. (Yes, I'm sticking with my old quote)
I used a master seal to promote colm. but you can find a promotion item on the top of the tower of Valnu. final boss. he carries either a random power up or promotion item.
I think the Spider monster in the corner of a later respawning monster map is the same way but he could just be power ups.
and of course there is the secret shops. theres a second secret shop a tad later. --- Anybody saying this is anime of the year will immediately be shut down when FMA comes out. -cloudvstidus4life | Posted: 2/17/2009
Another similar question, do I only get 2 Elysion whips? Because I need three to promote Tana, Vanessa, and Cormag. --- Being a former student in the art of sushi preparation, I know how the rice is suposed to be... - CykloneTiger
