Shadow Hearts: Covenant - Great Gama and the Man Festival

To upgrade Joachim's abilities, you'll need to face his teacher, Great Gama, three times.  You will also need to complete the Man Festival.

Muscle Arts

• Drain Touch: automatic.
• Grand Slam: face Great Gama the first time you visit Southampton.
• Deathtron Hammer: face Great Gama in Southampton before heading to Apoina Tower again.
• Artem Buster: face Great Gama in Nihonibashi.

Man Festival

You can tackle the Man Festival in Nihonibashi, after visiting the Azuka Stone Platform and gaining all of the Muscle Arts.  Speak to the Great Gama to begin.

Essentially, you're fighting through multiple battles.  You can save after every ten.  I found Mind's Eyes on Joachim, Yuri and Kurando helpful, and you'll want to bring Anastasia along when you can to take pictures.

The battles are easy.  For the last few, as long as you protect specific characters against specific status effects, you'll be fine.  Here's what you'll need.

• Kurando: Pocket Watch.
• Gepetto: Shell Bracelet.
• Lucia: Pocket Watch.
• Karin: Anne's Cross.
• Blanca: Will Power.
• Anastasia: Leonardo's Bear.
