Combat

Watchspiders spin webs to use as lairs but rove about hunting prey. They exhibit more of a pack mentality than true vermin and a degree of coordination unknown to their mindless relatives.

Poison (Ex): Injury, Fortitude DC 13; initial and secondary damage 1d4 Str. The save DC is Constitution-based.

Web (Ex): A watchspider often waits in its web or in a tree, then lowers itself silently on silk strands and leaps onto prey passing beneath. A single strand is strong enough to support a spider and one creature of the same size.

A watchspider can move across its own web at, its climb speed and can pinpoint the location of any creature touching its web.

Skills: Watchspiders have a +4 racial bonus on Hide checks, a +8 racial bonus on Climb and Spot checks, and a +10 racial bonus on Jump checks. A watchspider can always choose to take 10 on Climb checks, even if rushed or threatened. Watchspiders use either their Strength or Dexterity modifier for Climb checks, whichever is higher.
