The Hollow Star

ITEM 9

Price 700 gp

Usage held in 1 hand

Bulk 1

This roughly spherical mass of orange crystal is about the size of a human head. The sphere is opaque but glows from within as if it contained a bright flickering flame—the Hollow Star emits bright light in a 60-foot radius (and dim light to the next 60 feet). Any creature within the bright light of the Hollow Star gains a +1 item bonus to Occultism checks. Deros in the bright light shed by the Hollow Star suffer distracting but pleasant hallucinations and strange visions, and they become Stupefied 1 when in this illumination. If you're lawful, you're Enfeebled 2 while carrying the Hollow Star. If you touch the Hollow Star, your dreams the next time you sleep are strange, unsettling, hard to remember, and carry a vague sense of elation, doom, or both. Upon awakening, you must succeed at a DC 25 Will save or become Stupefied 1 by unsettling dreams that feel disturbingly like memories from a life lived on a distant dying planet.

The Keepers of the Hollow Star believe that this unique magical item, if allowed to bathe for an unspecified amount of time in sunlight, will bring Azathoth into that world's sun to destroy it. However, the item has no actual capacity to do so. Yet.

Activate (divination)

Trigger You cast a spell or use an effect that has the linguistic trait

Effect You speak in Aklo when using the linguistic spell or effect, even if you don't normally speak Aklo. If the spell or effect requires a spell attack roll, you gain a +1 item bonus to the roll. If the spell or effect can be resisted with a saving throw, all saves against the effect suffer a –1 item penalty.

Activate (death, emotion, fear, illusion, mental)

Frequency once per day

Effect The Hollow Star casts Phantasmal Killer (DC 25 Will, DC 25 Fortitude). The target of this effect receives a brief but overwhelming vision of the world ending as an immense explosion in the sky expands to engulf the world.

Activate (conjuration)

Frequency once per day

Effect The Hollow Star conjures an aberration to fight for you. This works like Summon Animal, except you summon a common creature that has the aberration trait and whose level is 3 or lower.
