FF Tactics: War of the Lions

[MagusKnight]

You get the ragnorak at the island where you fight Construct 7. (you find it by flushing out construct 7 and going to the end of the temple hallway) as for chirijiraden and chaos blade, they can both be treasure hunted during the septimus fight at the end of Midlight's Deep, which is the LAST bit of bonus dungeon. Afterwards, you can play on ad havoc mode for fun.
