Steps to Hide Dragoon/Murm Helmet

[Mikumo]

You can try the following procedure to hide those pesky goon or mum helmets that you might not like.

Tick the hide special hairstyles option to hide the helmets in your character equip screen

(Edit: this apparently only works if you switch hairdyes on itos ?, or something like hiding other hair accessories)

Using anvil and hitting it at least once removes the helmet too, but not the buff.
