以太蜘蛛 Ether Spider以太蜘蛛是来自灵界的致命捕食者，外形就像巨大的蛛形生物。以太蜘蛛的网并非用丝而是用灵界的原始精华（raw essence）编制而成，形成复杂的图案，能穿越模糊的虚空。在这些灵体巢穴中，以太蜘蛛可以窥见相邻的主物质位面，在黑暗偏远的土地上寻找容易猎取的猎物。一旦以太蜘蛛发现了猎物，就会将它的巢穴锚定，并在灵界等待猎物靠近。一旦猎物走到它附近，以太蜘蛛就会转移到物质位面，用它的尖牙啃咬它的猎物，然后转移到灵界等待毒液发挥效力。以太蜘蛛轻松地在位面之间移动，这使得那些无法看见或攻击虚体生物的人来说极其危险。
以太蜘蛛并非疯狂而邪恶的生物——他们只是简单地感到饥饿。如果以太蜘蛛那难以置信的胃口已经得到满足，余下的受害者甚至可以和它们交涉以求放过自己的生命。以太蜘蛛对于能帮助它们对抗敌人的物品、信息以及盟友都非常感兴趣。
最多可能有六只以太蜘蛛共同生活在一张灵体蛛网上，虽然以太蜘蛛喜欢群居，但是他们不像多数类人生物那样团结一致，而且当同伴倒下时更可能会去吃掉它们的尸体而非拯救它们免遭厄运。
以太蜘蛛巨大的巢穴在幽冥世界中漂流，在那里它们更容易放松警惕。那些碰见漂流中的以太蜘蛛巢穴的旅行者能更容易地和这些奇异的蛛形生物达成交易甚至结盟。它们的巢穴在超自然的能量流（metaphysical currents）中漂流，很少两次出现在同一地点。有时它们会对主物质位面上的某地产生兴趣，会把巢穴锚定在一个点上，形成一个半永久的家，知晓其位置的以太蜘蛛可以反复回到巢穴里。
以太蜘蛛的敌人 ETHER SPIDER FOES
和大多数地方相比，灵界是一个人迹罕至的地方，更多用来旅行而非居住。然而，这里浓厚的迷雾中隐藏着一些可怕的居民，例如畸形的寄生生物，他们利用类人生物作为孵化的苗床，以及因为凡人的原始恐惧而诞生的下界妖魔（fiends），而以太蜘蛛则一直警惕着那些敌人的阴谋诡计。

Ether Spider
Ether spiders are deadly predators from the Ethereal Plane resembling giant
arachnids. Rather than building webs of silk, ether spiders shape the raw
essence of the Ethereal Plane, weaving it in complex patterns that drift through
the misty void. From these ethereal nests, whole families of ether spiders can
scout the adjacent Material Plane, watching for easy prey in dark or remote
corners of the land of mortals. Once an ether spider has spotted a meal, it
anchors its nest and waits on the Ethereal Plane for its prey to draw near. As
soon as its victim is within reach, the ether spider shifts to the Material Plane,
clamps its fangs onto its prey, then shifts back to the Ethereal Plane to wait as
its venom works through the creature’s system. Ether spiders move between
the planes with ease, making them extremely dangerous to those who cannot
see or attack ethereal enemies.
Ether spiders are not mindless or evil—they are simply hungry. If a prospective
meal can sate an ether spider’s incredible appetite through other means, they
might be able to bargain for their life. Ether spiders are especially interested in
items, information, or allies who can help them against their enemies.
As many as half a dozen ether spiders might dwell in the same ether web.
Although ether spiders enjoy one another’s company, they don’t form the same
bonds as most humanoids, and they are more likely to feast on the
corpse of a fallen sibling than save one from certain doom.
Ether spiders dwell in vast nests adrift in the Ghost World,
where they are more likely to let down their guard. Travelers who
find a floating ether spider commune should have an easier time of
making peaceful contact to trade with or even befriend these strange
arachnids. The nests drift on metaphysical currents and are rarely
seen in the same vicinity twice. Sometimes a point of interest on the
neighboring Material Plane compels them to tether their nest to an area,
creating a semipermanent home, and those who learn its location can
return to it repeatedly.

Ethereal Step [one-action] The ether spider shifts to either the Ethereal Plane or the Material
Plane. The ether spider can remain on the Ethereal Plane indefinitely without ill
effect. While there, it can see clearly onto the Material Plane with a range of 60
feet. On its first round in an encounter, the ether spider can use this ability once as
a free action.
Ethereal Web Trap A creature hit by the ether spider’s web attack is immobilized and
stuck to the nearest surface (Escape DC 22).
Web Burst [two-actions] Frequency once per day; Effect The ether spider flings a gout of stored
webs in a 30-foot cone. These webs can pass between the Material Plane and the
Ethereal Plane. Each creature in the area is immobilized, as ethereal web trap, unless
it succeeds at a DC 22 Reflex save.
