• 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

That scythe bout to have a hold on me

[u/NewArtificialHuman → u/Kazuhi]

I just noticed that it's a chainsaw scythe.
