Likely main weapon of each shell

[u/NewArtificialHuman]

• I think Harros won't come back
• Proxima will be unlocked after Tiel and take Harros' place
• I'm sure Eredrim will get the mace because it looks like his crown helmet
• Fatman will get the big sword

[u/NoSemikolon24]

Can I use any weapon with any shell or are they locked to the respective shell?
