Hatred for Secret Doors
Cobblebone swarms have a hatred for secret doors, trick drawers, or anything else that conceals hidden spaces, as such things remind them of years or decades spent trapped within stone. They gain a +5 circumstance bonus to Athletics checks to Force Open secret doors.
Jutting BonesThe cobblebone swarm's space is difficult terrain.
Lifesense 40 FeetLifesense 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.
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.
Phantasmal Pummeling
Each foe in the cobblebone swarm's space takes 1d6[bludgeoning],1d6 void1d6 bludgeoning damage and 1d6 void damage (DC 17 reflex).
Settlement BoundA typical cobblebone swarm must remain in the settlement where it originated and can travel no farther than 1 mile from it without falling apart into component pieces, reviving if its pieces are returned to this area. Occasionally, cobblebone swarms are bound to a specific building, road, or district, rather than a settlement.
Occult Innate Spells (DC 18, +10 to hit)
Cantrips (2nd Level): Ghost Sound
Graydirge's necromancer-architects used a horrifying rending process to strip the flesh and souls off most bones involved in Graydirge's construction, but modern builders lack the benefit of such gruesomely efficient magic. When haunted bones are embedded in buildings alongside mundane materials, nearby bricks and cobblestones can be infused with necromantic energy. If no one exorcises the spirits haunting the bones, they become trapped and confused, their identities and memories intermingling. After several years, they can form cobblebone swarms, malevolent haunted amalgamations of brick and bone. These vengeful creatures conjure ghostly noises to lure victims down narrow alleys or into dark stone basements, where they pummel them to death and cover their remains beneath piles of bones and brick.
Some have mistaken cobblebone swarms for cobbleswarms, but citizens of Graydirge know to look for nearby apparitions, or studded bones that move when you look away. These are sure signs of a cobblebone swarm, and an indication that one should take a different route to their destination.
Cobblebone swarms look like piles of simple bricks or cobblestones with crooked bones embedded in them, often in the shape of crude faces. As they roll along or float slowly through the air, they leave a ghostly afterimage in their wake.
Traits
This rarity indicates that a rules element is very difficult to find in the game world. A rare feat, spell, item or the like is available to players only if the GM decides to include it in the game, typically through discovery during play. Creatures with this trait are rare. They typically can't be summoned. The DC of Recall Knowledge checks related to these creatures is increased by 5.
EarthEffects with the earth trait either manipulate or conjure earth. Those that manipulate earth have no effect in an area without earth. Creatures with this trait consist primarily of earth or have a connection to magical earth.
SwarmA swarm is a mass or cloud of creatures that functions as one monster. Its size entry gives the size of the entire mass, though for most swarms the individual creatures that make up that mass are Tiny. A swarm can occupy the same space as other creatures and must do so in order to use its damaging action. A swarm typically has weakness to effects that deal damage over an area (like area spells and splash weapons). Swarms are immune to the grabbed, prone, and restrained conditions.
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.
