Monstrous Spider

Monstrous spiders come in two general types: hunters and web spinners.

Species Traits

Monstrous spiders have the following traits.

Speed: Hunting spiders are speedier than their web-spinning counterparts. Increase the normal speed of hunting spiders by 10 feet. Climb speed remains unchanged.

Table: Monstrous Spider Poison
Spider Size Fort Save DC Initial/Secondary Damage
Colossal 35 2d8 Str
Gargantuan 31 2d6 Str
Huge 22 1d8 Str
Large 17 1d6 Str
Medium-size 14 1d4 Str
Small 11 1d3 Str
Tiny 11 1d2 Str

Poison (Ex): A monstrous spider injects poison into its victim with a successful bite. The victim must succeed on a Fortitude save or take the initial damage; a second Fortitude save must be made 1 minute later to negate the poison’s secondary damage. The DC of the Fortitude saves and the effects vary depending on the monstrous spider’s size, as shown on Table: Monstrous Spider Poison.

Web (Ex): Monstrous spiders often wait in their webs 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.

Web-spinning spiders can cast a web eight times per day. Casting a web is a melee touch attack with a maximum range of 50 feet and a range increment of 10 feet, and the web is effective against targets up to one size category larger than the spider. The web anchors the target in place, allowing no movement. An entangled creature can escape with a successful Escape Artist check or burst it with a Strength check. Both are attack actions whose DCs are given in Table: Monstrous Spider Webs.

Web-spinning spiders often create sheets of sticky webbing from 5 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 Spot check (DC 20) 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 the hit points listed on below and damage reduction 5/fire.

A monstrous spider can move across its own sheet web at its climb speed and can determine the exact location of any creature touching the web.

Huge 28 30 14
Large 26 28 12
Medium-size 20 22 6
Small 18 20 4
Tiny 16 18 2

Resistance to Massive Damage: Monstrous spiders gain a +5 species bonus on Fortitude saves to negate the effects of massive damage.
