Change Shape (Su)

An aranea can take the form of a Small or Medium humanoid or spider-humanoid hybrid. In humanoid form, an aranea cannot use its bite, web, or poison. In spider-humanoid hybrid form, an aranea looks like a humanoid with spidery fangs and spinnerets, with the latter typically located at the small of its back. The aranea retains its bite attack, webs, and poison in this form, and can wield weapons and wear armor. When in humanoid or hybrid form, an aranea’s speed is 30 feet and it has no climb speed.

Poison (Ex)

Bite—injury; save Fort DC 14; frequency 1/round for 6 rounds; effect 1d3 Strength; cure 1 save.

An aranea is an intelligent, shapechanging spider with sorcerous powers. In its natural form, an aranea resembles a humpbacked spider a little bigger than a human, and weighs about 150 pounds. The hump on its back houses the aranea’s brain. All araneas have a single alternate form as well—this alternate form is that of a Small or Medium humanoid. Although an aranea can assume a spider-hybrid variant of this form, it cannot use its change shape ability to assume multiple humanoid forms—this additional shape is locked into one unique appearance.

Araneas typically gather in small colonies of two to six individuals, making webbed nests high in trees. These colonies work together to research magic, and may change membership many times over as individuals leave to pursue their own studies and are replaced by newer members. A single aranea may take on humanoid form and live for years in a humanoid community, never revealing its true nature. Though araneas generally prefer to be left alone, they often prove quite knowledgeable about the ways of magic, and if approached peacefully may be willing to share their expertise for the right price (typically a magic item or some service).

Skilled spellcasters, araneas try to avoid physical combat and use their webs and spells when they can. Rather than kill their enemies, araneas often subdue opponents and hold them for ransom.

Alternative Tactics

Web-Slinging: A favored tactic of araneas involves creating a web and then using that web as a swinging rope to fight from. Generally speaking, the aranea is considered to be on higher ground for these attacks (+1 on melee attacks). To use this tactic, an aranea must first throw a web to a nearby fixed point (usually a ceiling or beam, both of which are generally Large, with an AC of 9). Araneas make one of three attacks using their webs in this way.

Angry Falling Leaves: In this attack, an aranea uses its web to break its fall as it suddenly drops up to 30 feet downward into combat, treating itself as a falling object that crashes into an opponent from above. This attack requires a melee touch attack, and deals 3d6 points of damage. The aranea itself takes 1d6 points of damage if this attack is successful.

Attack of the Lotus Whirlwind: In this attack, an aranea puts itself into a spin as it descends from its web. If the aranea descends 20 feet or more using this attack, its descent counts as a charge.

Graceful Descent of the Flying Blade: An aranea can swing up to the web’s length (moving up to the aranea’s speed) and make a single melee attack action without provoking an attack of opportunity, similar to the Spring Attack Feat. Doing so requires an Acrobatics check with a DC equal to the opponent’s CMD. The aranea then releases the web and drops to the ground.
