Impalement (Ex): Against formidable prey, a sword spider jumps high into the air to land atop an opponent, with all eight legs together in a tight mesh of blades. It makes only a single attack roll (+5 melee), but if that attack is successful, the opponent takes damage from three leg blades if size Small or smaller, four blades if Medium-size, five blades if Large, six if Huge, and all eight if Gargantuan or larger. If the spider descends more than 20 feet to make this attack, it adds +1 point of damage to each leg.

Poison (Ex): Those hit by a sword spider's bite attack must succeed at a Fortitude save (DC 16) or be injected with poison. The initial and secondary damage is 1d6 points of temporary Strength damage.

Skills: Sword spiders have racial bonuses of +4 on Hide checks, +6 on Jump checks, and +12 on Spot checks.

Sword spiders lash out with the sword-like blades on each leg in melee combat. They can direct their attacks against creatures on all sides, but usually cannot bring more than four legs to bear against a single enemy

Sword spiders are about 12 feet in diameter, with a sleek, hairy black body, striped with dark brown fun Their. legs have chitinous plates with raised, sharp ridges that cut like sword blades, hence the spider's name.
