Dimitra carrys a set of twin blades named Storm Caster for the rare materials they are made from. Stormsilver, the metal Storm Caster was forged from, is naturally resistant to magic and corrosive poisons, potions, spells, liquids, solids (cannot be corroded, even with time). They are also bound to Dimitra by the manner of souls, vanishing from existence when her soul leaves her body.
She carries one on each hip in case she cannot reach her violin or harness her fire magic, bound in leather sheaths.
