You empower a hex through the ritual preparation of a ceremonial dagger.
Prerequisites: Witch class.
Benefit: Each day you can select a masterwork or magical dagger, transforming it into a hexknife. Choose one hex to empower for that day - when holding the hexknife in one hand this hex gains a +1 bonus to its DC for a number of rounds equal to 3 + your Intelligence modifier. These rounds do not need to be consecutive.
Special: The Witchfinder multiclass archetype may select his feybane weapon in place of a hexknife. Similarly, the Scarred Witch Doctor may substitute his fetish mask, the Bonded Witch her bonded item, or the Gauntlet Witch her eldritch gauntlet in place of a hexknife.
