This appears as a great roiling mass of fragile looking spiders, all minuscule bodies and extraordinarily long, arched legs. One then sees the great fangs that arch from their nigh invisible mouths and curve down almost to the ground...
Vicious longlegs are the deadly cousins of the daddy-longlegs. Though they are rare, such is the fear they instill that many go to pains to eradicate even their harmless relatives.
Combat
Vicious longlegs are terrifying creatures that cover great swathes of areas. They will sometimes ignore trespassers and then suddenly bunch together in a feeding frenzy that leaves nothing but bones behind. The swarm deals 1d6 points of damage to any creature whose space it occupies at the end of its move.
Clinging (Ex): Any creature that takes damage from the swarm must succeed on a DC 15 reflex save or be covered in the creatures even if he leaves the swarm's space. Unless he spends a full round action knocking off the longlegs he continues to take damage at the end of each of his turns as if he were still in the swarm's space.
Distraction (Ex): Any living creature that begins its turn with a vicious longleg swarm in its space must succeed on a DC 13 Fortitude save or be nauseated for 1 round. The save DC is Constitution-based.
Mimicking (Ex): Knowledge (nature) checks to identify a vicious longleg swarm is increased by +4. Those who fail their check incorrectly identify them as the harmless daddy longlegs.
Poison (Ex): Injury, Fortitude DC 15, initial and secondary damage 1d4 Con. The save DC is Constitution-based.
Skills: A vicious longleg swarm has a +4 racial bonus on Hide and Spot checks and a +8 racial bonus on Climb checks. It uses its Dexterity modifier instead of its Strength modifier for Climb checks. It can always choose to take 10 on a Climb check, even if rushed or threatened.
