Ecology
Phase spiders dwell in caves, cellars, ruined estates, and any environment where the borders between Material and Ethereal Planes are thin. They feed on beasts and humanoids, dragging victims to ethereal lairs to digest in safety. They reproduce by laying eggs in ethereal pockets, with hatchlings emerging years later. They live for decades. They share territory with other ethereal creatures, often unaware of physical neighbors. Their bites deliver paralytic venom that subdues prey for transport between planes.
Behaviour
Phase spiders are cunning ambushers, using ethereal travel to strike from impossible angles. They prefer hit-and-run tactics, biting and retreating before retaliation. They communicate via vibration-signals to other phase spiders, coordinating attacks on shared prey. They take no pleasure in killing, viewing it as feeding. They flee to the Ethereal Plane when threatened, returning later from different positions. They despise sunlight and avoid open spaces. They mate violently, with females often consuming males after copulation.
Origin
Phase spiders are believed to descend from giant spiders that were exposed to ethereal magic in ancient cataclysms, gaining planar mobility. Some sages argue they emerged naturally from the Border Ethereal, drifting to the Material Plane during cosmic alignments. Their venom contains traces of ethereal energy, useful in alchemy and divination. Some druid circles consider them sacred to liminality, channeling their essence in ritual. Their molted shells fetch high prices among ethereal-magic specialists.
