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.
Stench (aura, olfactory)10 feet. A creature entering the aura or starting its turn in the aura must succeed at a DC 26 fortitude save or become Sickened 1 (plus Slowed 1 as long as it's sickened on a critical failure).
While within the aura, the creature takes a -2 circumstance penalty to saves against disease and to recover from the sickened condition. A creature that succeeds at its save is temporarily immune for 1 minute.
Effect: Stench
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.

Paralysis (incapacitation, occult)Any living creature hit by a ghast's attack must succeed at a DC 26 fortitude save or become Paralyzed. It can attempt a new save at the end of each of its turns, and the DC cumulatively decreases by 1 on each such save.
Sneak AttackThe ghast's Strikes deal an additional 2d6 precision damage to Off-Guard creatures.

Traits
Something of uncommon rarity requires special training or comes from a particular culture or part of the world. Some character choices give access to uncommon options, and the GM can choose to allow access for anyone. Less is known about uncommon creatures than common creatures. They typically can't be summoned. The DC of Recall Knowledge checks related to these creature is increased by 2.
GhoulGhouls are vile undead creatures that feast on flesh.
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.
