  A great orb spider, larger than a human, with the globular body,  large spinnerets, and long, precise legs of a web-spinner. Its many eyes  gleam with a curious attentiveness — or is it intelligence?
 
A rigger spider is specially bred to maintain and operate a Xan Kraban   windship’s rigging. The rigger spider is second only to the captain in  importance, and is closely guarded.  It helps the drow crew by adjusting  sails and yardarms, or spins silk webbing to repair damaged sheets and  lines. Most windships are gifted with but a single rigger  spider.  All  other Xakhun spiders are raised with an  inbred respect for the rigger  spider and never conceive of attacking  one, even if the rigger spider  strikes first.
 
A typical rigger spider's body is 8 feet long. It weighs about 700 pounds.
 
COMBAT
 
Rigger spiders have no interest in combat and usually leave fighting to  the rest of the crew. However, they are easily enraged by threats to  their precious rigging, bitterly attacking any intruder who harms their  ship's sailing ability. An attacking rigger spider usually throws webs  first, then closes in to administer its poisonous bite to entangled  opponents.
 
 Poison (Ex): Injury, Fortitude DC 13, initial and secondary damage 1d8 Con. The save DC is Constitution-based.
Resistance To Gas Attacks (Ex): Rigger spiders have a +4 racial bonus on all saving throws against gas attacks, including inhaled poisons and such spells as stinking cloud or cloudkill.
 
Web (Ex): Rigger spiders often wait in  their ship's rigging or in trees, then lower themselves silently on silk  strands and leap onto prey passing beneath. A single strand is strong  enough to support the spider and one creature of the same size. Rigger spiders can throw a web eight 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 up to one size  category larger than the spider. An entangled creature can escape with a  successful DC 15 Escape Artist check or burst it with a DC 19 Strength  check; such escape attempts are standard actions. The check DCs are  Constitution-based, and the Strength check DC includes a +4 racial  bonus.
Rigger spiders often create sheets of sticky webbing from 20 to 60 feet square, depending on the size of the spider. They usually position these sheets to snare flying creatures but can also try to trap prey on the ground. Approaching creatures must succeed on a DC 20 Spot check to notice a web; otherwise they stumble into it and become trapped as though by a successful web attack. Attempts to escape or burst the webbing gain a +5 bonus if the trapped creature has something to walk on or grab while pulling free. Each 5-foot section has 12 hit points (14 hit points for a Huge-sized spider), and sheet webs have damage reduction 5/—.
A rigger spider can move across its own web at its climb speed and can pinpoint the location of any creature touching its web. 
 
 Skills: Rigger spiders have a +4 racial bonus on  Hide and Spot checks, and a +8 racial bonus on Climb checks. A rigger spider can always choose to take  10 on Climb checks, even if rushed or threatened. Rigger spiders use  either their Strength or Dexterity modifier for Climb checks, whichever  is higher.
*Rigger spiders have a +8 racial bonus on Hide and Move Silently checks when using their webs.
