The Threefold Conspiracy: Puppets Without Strings pg. 51
A spell sergeant trains with weapons as much as with spells, and you’ve learned to combine the two. You can cast spells with a range of touch into a melee weapon you hold. The spell is held within your weapon for up to one minute; if you successfully hit an enemy with the weapon, the spell discharges, targeting that enemy. If you are no longer holding the weapon, the spell dissipates harmlessly. Spell damage and weapon damage affect the target separately. If the spell you cast allows an attack as part of casting the spell (such as jolting surge), you can cast the spell into your weapon and attack in the same turn. In addition, for the purpose of meeting feat prerequisites, you treat your class level as your base attack bonus.
