Board the Lunar Whale and interact with the Crystal to go back to Earth, Baron Castle.
Remember way back when you talked to the Baron king in the castle basement? Let's go back there to get our last non-secret summon.
Boss: Odin
The key to defeating him is to finish him as soon as possible. He has 20001 HP, and you have to kill him before he uses Zantetsuken, which can wipe out your whole team.
- Everyone uses their most powerful attack.
- Rydia casts Thundaga.
- Rosa can either attack with a Bow or cast Holy (you may not have learned it).
- Edge uses Blitz.
Rydia now learned Odin.
An achievement Summon Master is unlocked.
