(Drow of the Underdark variant, p. 65)

By discarding the religious traditions dominating drow culture, the arachnomancer finds a different way to serve the Weaver of Webs. Through careful study, the arachnomancer comes to understand spiders in a unique and disturbing way, developing a rapport with the vermin. It doesn't take long for the arachnomancer to shape his magical studies to awaken the Spider Queen's blessings within himself, allowing him to assume the form of a monstrous spider.

Class Features

Spellcasting: At 1st, 3rd, 4th, 6th, and 7th level, you gain new spells per day and an increase in caster level (and spells known, if applicable) as if you had also gained a level in a spellcasting class to which you belonged before adding the prestige class level. You do not, however, gain any other benefit a character of that class would have gained. If you had more than one arcane spellcasting class before becoming an arachnomancer, you must decide to which class to add each level for the purpose of determining spells per day, caster level, and spells known.

Poison Save Bonus (Ex): You gain a bonus on saving throws against poison equal to your class level.

Handle Spiders (Ex): You gain a +5 bonus on skill checks to use the Handle Animal skill with spiders (see page 46).

Spider Domain: You gain access to the Spider domain and the granted power associated with the domain (rebuke spiders as an evil cleric rebukes undead, a number of times per day equal to 3 + your Cha modifier). If you already have access to one or more domains, you can now choose spells from this domain as your daily domain spells. If you do not already have a domain, each day you can prepare one domain spell for each level you can cast, from 1st on up. See the deity, domains, and domain spells cleric class feature, PH 32.

Spider Shape (Su): At 2nd level, you can change into a Small, Medium, or Large monstrous spider (either hunting or web-spinning) and back again three times per day. At 5th level, you can also take the form of a Tiny or Huge monstrous spider, and at 8th level, you can take the form of a Gargantuan monstrous spider. The effect lasts for 1 hour per arachnomancer level. This ability functions as wild shape, so you can select and use the Natural Spell feat. See the wild shape druid class feature, PH 37.

Tremorsense (Ex): Starting at 3rd level, you can detect and pinpoint any creature or object within 20 feet. At 6th level, your tremorsense extends to 60 feet. You can use this ability five times per day. Activating this ability is a swift action, and it lasts for a number of rounds equal to your arachnomancer class level.

Webwalking (Su): Starting at 4th level, you can ignore webs (magical or nonmagical) as if you were under the effect of a freedom of movement spell. You can climb webs at your normal land speed without needing to make Climb checks and walk along webs without needing to make Balance checks.

Climb Speed (Ex): At 7th level, you gain a climb speed equal to your normal land speed. In addition, you gain a +8 bonus on Climb checks and you can always choose to take 10 on these checks, even if rushed or threatened.
