Araneas speak Common and Sylvan.
Araneas avoid physical combat and use their webs and spells
when they can. In a battle, they try to immobilize or distract
the most aggressive opponents first. Araneas often subdue
opponents for ransom.
Spells: Araneas cast spells as 3rd-level sorcerers (save DC 12
+ spell level). They prefer illusions and charms but avoid fire
Web (Ex): In spider or hybrid form (see Alternate Form,
below), an aranea can cast a web up to six times per day. This is
similar to an attack with a net but has a maximum range of 50
feet, with a range increment of 10 feet, and is effective against
targets of up to Large size. The web anchors the target in place,
allowing no movement. An entangled creature can escape with a
successful Escape Artist check (DC 20) or burst the web with a
successful Strength check (DC 26). The web has 6 hit points and
takes double damage from fire.
Poison (Ex): Bite, Fortitude save (DC 13); initial damage 1d6
temporary Strength, secondary damage 2d6 temporary Strength.
Alternate Form (Su): An aranea's natural form is that of
a Large monstrous spider. It can assume two other forms. The
first is a Small or Medium-size humanoid (the exact form is fixed
at birth). The second form is a Medium-size, spider-humanoid
hybrid. Changing form is a standard action. In humanoid form, the
aranea gains all the abilities of the form (for example, an
aranea in dwarf form has dwarven racial traits). The aranea keeps
its ability scores and can cast spells, but it cannot use webs or
poison in humanoid form. In hybrid form, an aranea looks like a
humanoid at first glance, but a successful Spot check (DC 18)
reveals the creature's fangs and spinnerets. The aranea can
use weapons and webs in this form. An aranea remains in one form
until it chooses to assume a new one. A change in form cannot be
dispelled, nor does the aranea revert to its natural form when
killed. A true seeing spell, however, reveals its natural form if
it is in humanoid or hybrid form.
