As mentioned in a previous thread many people actually kept alle her weapons after she died.
Indeed. I always equip her with a weapon that I've got two of (Striking staff, for example) so as not to lose either the Princess Guard, Guard Stick, Wizer Staff or Wizard Staff when she dies.
She wasn't my favourite all time game character (Celes Chere is! ) but she was great none the less. And I'm not too fond of sweet and loveable characters, either.
