Frefferth
CREATURE 9Lifesense allows a monster to sense the vital essence of living and undead creatures within the listed range. The sense can distinguish between the vitality energy animating living creatures and the void energy animating undead creatures, much as sight distinguishes colors.
A monster with this ability regains the given number of Hit Points each round at the beginning of its turn.
30 feet. DC 25 Will
A creature that first enters the area must attempt a Will save.
Regardless of the result of the saving throw, the creature is temporarily immune to this monster's Frightful Presence for 1 minute.
Critical Success The creature is unaffected by the presence.
Success The creature is Frightened 1.
Failure The creature is Frightened 2.
Critical Failure The creature is Frightened 4.
When Frefferth is destroyed, his body and items dissipate into shadowy nothingness and the knight re-forms after 1d4 days within the sarcophagus in area D12, fully healed.
Frefferth can be trapped only by returning the Chain of the Stilled Spirit to the sarcophagus (see areas D12 and D34), in which case Frefferth's body dissipates, leaving his items in the spot where he was last slain.
Any slashing weapon a dullahan wields becomes Keen, and any hatchet it wields becomes Returning.
If the dullahan kills a creature with a critical hit using a slashing weapon, the target is decapitated as though the dullahan had used Reap on the target.
These effects remain only while the dullahan holds the weapon.
Whenever Frefferth damages a creature with a critical hit using a ranged piercing weapon, the weapon remains impaled in the victim's body.
The victim becomes Clumsy 1 as long as they are impaled; the impaling weapon can be removed by the affected creature or an adjacent ally as a 2-action activity that has the manipulate trait.
Frefferth removes the head of a dead creature within reach.
Each creature within the area of Frefferth's frightful presence must attempt a new save, even if they are temporarily immune.
