From publisher blurb: The Grey Arrow archetype offers abilities that specialize in punishing spellcasters and creatures benifiting from magical effects. Grey Arrows are taught by members of an old order of mage hunters. Originally wardens who helped to keep the threat of magic at bay, their order has all but fallen apart. Outside certain splinter groups they hunt individually. They know techniques that target a mage's connection to the weave, and cause their control over its power to falter.
