Trigger A creature within the monster's reach uses a manipulate action or a move action, makes a ranged attack, or leaves a square during a move action it's using.
Effect The monster attempts a melee Strike against the triggering creature. If the attack is a critical hit and the trigger was a manipulate action, the monster disrupts that action. This Strike doesn't count toward the monster's multiple attack penalty, and its multiple attack penalty doesn't apply to this Strike.
Void HealingA creature with void healing draws health from void energy rather than vitality energy. It is damaged by vitality damage and is not healed by vitality healing effects. It does not take void damage, and it is healed by void effects that heal undead.
Command Skeletons (divine)The skeletal Hellknight 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 Hellknight is active and commanding the skeletons, they gain the Attack of Opportunity reaction.
Invoke Reckoning
(divine, mental)Trigger The skeletal Hellknight hits a foe with a Strike.
Effect The skeletal Hellknight causes the creature struck to endure the pain of an Order of the Nail's reckoning-a rite of mortification Hellknights 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 piercing damage to the victim.
Traits
A rules element with this trait is one-of-a-kind. The DC of Recall Knowledge checks related to creatures with this trait is increased by 10.
SkeletonThis undead is made by animating a dead creature's skeleton with void energy. An ability with this trait can be used or selected only by skeletons.
UndeadOnce living, these creatures were infused after death with void energy and soul-corrupting unholy magic. When reduced to 0 Hit Points, an undead creature is destroyed. Undead creatures are damaged by vitality energy and are healed by void energy, and don't benefit from healing vitality effects.
UnholyEffects with the unholy trait are tied to powerful magical forces of cruelty and sin. They often have stronger effects on holy creatures. Creatures with this trait are strongly devoted to unholy causes, and often have weakness to holy. If a creature with weakness to unholy uses an unholy item or effect, it takes damage from its weakness.
