You call that a flameblade?

Prerequisites: Archetype connected to some element, Spell infused strikes, Ability to cast third level spells

Benefit: When using Spell infused Strikes you may choose to substitude the 3rd level sacrifice benefits by converting the entire damage to elemental damage. The element must be corresponding to your class, i.e, Hyperborean - cold, Pyromancer - fire, Thundercaller - lightning. The spell infused strikes also receive the cold/fire/lightning descriptor.
