Spell-like Abilities: At will -- darkness, fear, scare, telekinesis, teleport without error (self plus 50 pounds of objects only). These abilities are as the spells cast by a 7th-level sorcerer (save DC 10 + spell level).

Poison (Ex): Bite, Fortitude save (DC 15); initial and secondary damage 1d6 temporary Strength.

Web (Ex): Eight times per day a spithriku shoot a web from its abdomen. This attack is like a web spell, with a few exceptions. The range is 50 feet, and the webs are permanent, non-magical, and cannot be dispelled. The DC for evading or breaking free from the webs is 15, and there is a 75% chance that the webbing won't burn if any sort of fire is applied to it (check each round).

The spithriku can perform one of the following special tactics with its webs once per round.

See Invisible (Su): A spithriku can continuously see invisible creatures as the spell cast by a 7th-level sorcerer.

Demon Qualities (Ex): Immune to poison and electricity; cold, fire, and acid resistance 20.

Telepathy (Su): Spithriku can communicate telepathically with any creature within 100 feet that has a language.

Summon Demons (Sp): Once per day a spithriku can attempt to summon 2d8 kakkuu or 1d4 spithriku with a 35% chance of success.

The spithriku's coloration gives it a +8 racial bonus to Hide checks.

The Spithriku Spyder-Fiend first appeared in the Rod of Seven Parts Boxed Set (Skip Williams, 1996)

Chaotic Subtype

A subtype usually applied only to outsiders native to the chaotic-aligned Outer Planes. Most creatures that have this subtype also have chaotic alignments; however, if their alignments change they still retain the subtype. Any effect that depends on alignment affects a creature with this subtype as if the creature has a chaotic alignment, no matter what its alignment actually is. The creature also suffers effects according to its actual alignment. A creature with the chaotic subtype overcomes damage reduction as if its natural weapons and any weapons it wields were chaotic-aligned (see Damage Reduction).

Evil Subtype

A subtype usually applied only to outsiders native to the evil-aligned Outer Planes. Evil outsiders are also called fiends. Most creatures that have this subtype also have evil alignments; however, if their alignments change, they still retain the subtype. Any effect that depends on alignment affects a creature with this subtype as if the creature has an evil alignment, no matter what its alignment actually is. The creature also suffers effects according to its actual alignment. A creature with the evil subtype overcomes damage reduction as if its natural weapons and any weapons it wields were evil-aligned (see Damage Reduction).
