The Scourge of Woodsedge
CREATURE 15The Scourge senses the vital essence of living creatures within range.
Lifesense 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.
DC 36 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.
Note: A radius for this aura was not provided by Paizo
A 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.
The Scourge has a fly speed of 30 feet, but must end its turn within no more than 5 feet off the ground, otherwise it falls and takes damage as normal
A creature damaged by the Scourge's blade Strikes must succeed at a DC 36 Fortitude save or become Drained 1; if the target is already drained, they instead increased their drained value by 1, to a maximum of Drained 3. On a critical failure, the target is also Paralyzed until the end of the Scourge's next turn.
The Scourge explodes into a whirling tornado of metal and blades, at the cost of briefly leaving its warshard core vulnerable. All creatures within a 20-foot emanation must succeed at a DC 33 Reflex save or take 10d10 slashing plus 3d8 void damage. The Scourge can't use To Shreds for 1d4 rounds.
If the Scourge is targeted by a Reactive Strike as a result of using this action, it takes a –2 circumstance penalty to its AC; if the Reactive Strike disrupts this action, this penalty remains until the start of the Scourge's next turn.
Effect: To Shreds (AC Penalty)
