Frightful Fridays! Bone Spider

Hello and welcome back to Frightful Fridays! It's been quite some time since I've featured a spider here, so I've got two spiders for you. The bone spider is a teeny spider that likes to eat your bones, but it's too small to eat an entire skeleton on its own. Instead, it uses the skeletons it harvests to build a massive skeletal spider and uses those to create mayhem and kill more victims.

I hope you enjoy the bone spider, and I'll see you next week with another monster!

Not pictured: the spider driving this thing

This red spider has chalky outlines that look like humanoid bones lining its legs, thorax, and abdomen. Viscous green liquid sizzles when it drips from its mandibles and hits the ground.

Animation Cessation (Su) A bone spider that uses its animate dead spell-like ability can end the effect for skeletons it animates. This effectively destroys the undead, and they cannot be animated again.
Bone Spider Casing (Ex) A bone spider that has extracted enough bones to build a Colossal skeleton shaped like a spider can spend 2 days to build a bone spider casing (see below). It must use a Colossal creature’s skeleton or the equivalent (2 Gargantuan creatures, 4 Huge creatures, 8 Large creatures, etc.) to create the casing.
A bone spider must be in the contact with the casing in order to control it, which requires a standard action. While the spider is within the casing it has total cover and cannot be targeted by effects or attacks that require line of sight or line of effect. It is still subject to spells or effects that affect an area.
A bone spider can spend 1 minute to repair a bone spider casing, healing it 1d8 hit points with a Small creature’s skeleton, 2d8 hit points with a Medium creature’s skeleton, 4d8 hit points with a Large creature’s skeleton, and 8d8 hit points with a Huge or larger creature’s skeleton.
Extract Skeleton (Su) If a bone spider is touching a corpse, it can rip the bones from the corpse's flesh as a full-round action. Creatures witnessing this must succeed on a DC 18 Will save or become shaken. This is a mind-affecting fear effect. The save DC is Charisma-based.
Oracular Spider (Su) A bone spider gains revelations as if it were an oracle with the bones mystery. Its oracle class level equals its Hit Dice. Additionally, the spider can use the mystery's bonus spells as spell-like abilities once per day each.
A typical bone spider chooses armor of bones, death’s touch, and soul siphon as its revelations.
Poison (Ex) Bite—injury; save Fort DC 18; frequency 1/round for 6 rounds; effect 1d6 Str; cure 2 consecutive saves. A victim reduced to 0 Strength due to this poison dies.


This enormous skeleton shaped like a spider is composed of bones from a plethora of creatures and held together by thick webbing.

Breath Weapon (Su) A bone spider casing can only use its breath weapon 3 times per day.

Bone spiders are intelligent arachnids that feed on bone matter and have a preternatural capacity for reshaping it. Despite their potent acid and deadly poison, they felt their miniscule size made them less imposing than they wished to be. They turned their boneshaping abilities toward creating soul-charged skeletons as large as the mightiest creatures to walk the earth. The spiders pilot these creations to impose their will and to harvest more bones from victims, usually to effect repairs on their war machines. Especially powerful bone spiders have at least two such bone casings built and ready for use.

Bone spiders rarely cooperate with each other and typically only long enough to reproduce and stand guard over unhatched eggs. Bone spider coupling usually ends when their newborn spiders hatch. The parents then combat each other with their spider skeletons, with the winner destroying the loser. The newborn spiders use the remains from these massive battles to create their own, much less impressive versions to best their siblings. Among hundreds of baby spiders, only a handful survive this grand melee.
