Spellblade

You have skills both martial and magical. When you incorporate a cantrip or great tier magical effect into a weapon attack, you may now hold that bonus as a concentration effect and it remains until your concentration is broken, dealing the effect each time the weapon hits. You may also incorporate a superior spell into a weapon attack, but each additional time the effect goes off, you lose 1 Spirit. When your Spirit is depleted, that energy is no longer bound up in your weapon. 
Your concentration is also never broken by injuries.
