Feat: Runic Mind Smithing

You focus your mind on thoughtforms of fundamental magical forces, shaping them into a property rune that you mentally etch onto your mind weapon. During your daily preparations, choose one rune from the following list of weapon property runes: corrosive, flaming, frost, shock, thundering, and vitalizing. You enhance your weapon with the chosen rune until your next daily preparations. This rune counts toward your maximum limit of runes as normal.
