Trapdoor Spider Tactics
Trap door spiders lie in wait in their burrows until a creature passes within 2 squares, at which point the spider uses pounce to drag the unfortunate victim into its burrow. Once a creature is inside the spider's burrow, the spider will bite the victim repeatedly until it dies.
Trapdoor Spider Lore
A character knows the following information with a successful arachana or nature check.
- DC 10 (arachana), DC 15 (nature): Trapdoor spiders are ambush predators. They typically lie in wait under trapdoors and pounce on passing prey.
- DC 20 (arachana), DC 25 (nature): Though trapdoor spiders are typically solitary, some are members of so-called "spider colonies". Such colonies cannot exist without guidance from a more intelligent being, such as an arachnomancer or demonspider. Within colonies, trapdoor spiders are usually used to guard important areas of the colony.
Encounter Groups
Trapdoor spiders regard most creatures (even each other) as prey, though they may be found among other spiders or spiderkind.
