Trapdoor Spider (4e Creature)
Trapdoor Spider[edit]
Trapdoor spiders are the ultimate ambush predators. They typically build a large burrow with a camoflaged trapdoor of dirt and silk to hide under. When prey passes by the trap door, the trap door spider pounce upon the unforunate victim.

Trapdoor Spider Tactics[edit]
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[edit]
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[edit]
Trapdoor spiders regard most creatures (even each other) as prey, though they may be found among other spiders or spiderkind.
