Bia

Bia is a sword designed for and is the weapon of choice for Cassandra, the blade is made from heavy alloys giving it significant moment and weight with an incredibly sharp edge. The blade also features a trigger which when activated charges and deploys a magnetic field holding burning hot plasma around the blade, allowing it to either to burn, cut, or both burn and cut whatever is getting in the way. This trigger works from an internal battery that can be charged outside of combat, if the charge is run out the energy is taken directly from the user's stone. A full charge will only last for a total of 56 seconds so actively running it when needed is not ideal. The blade features hydraulics which allow it to fold outside of combat for easier carry. It is modeled off a Katana.

A variant of this sword exists allowing for dual wields, Bia Cress and Bia Wreath are two short swords which are near identical to Bia save for a shorter charge and lack of hydraulic folding.
