Command Skeletons (divine, necromancy) The skeletal Maefalei can direct the actions of the nearby skeleton guards, commanding them to perform tactics such as flanking foes and focusing their attacks on specific targets. As long as the skeletal Maefalei is active and commanding the skeletons, they gain the Attack of Opportunity reaction.

Invoke Reckoning [R] (divine, enchantment, mental) Trigger The skeletal Maefalei hits a foe with a Strike. Effect The skeletal Maefalei causes the creature struck to endure the pain of an Order of the Nail's reckoning—a rite of mortification Moribaetond of that order use to focus their minds. The creature struck feels as if nails are being driven into their body, and must succeed at a DC 17 Will save or be stunned 1 from the pain. On a critical failure, the pain manifests as actual puncture wounds, dealing an additional 2d6 points of piercing damage to the victim.
