Absorption: you can will your shield to roll a weapons vs the shifts of power in a spell effect,and absorb that much. As a subsequent action. If your beat it, the entire spell's energy absorbed. If not, subtract it from the total and the spell hast that many shifts of power left.
Example: Wizard places a maneuver on you using a spell that caused the vines in the area to grab you. He summoned 10 shifts to do it, rolled a discipline of 8. You defend with a 4. On your turn, as a subsequent action, you allow the weapon(obviously it needs to be magical) to absorb the magic. You roll a weapons and get a 7. Out of the 10 shifts used to animate the vines to hold you, you absorb 7 and 3 remain, so on the next exchange you can absorb the remaining 3 and spell falls apart.
Deflect magic: this allows you to deflect magic evocations that are either a beam or a ball of energy, rolling weapons with a +2.
