Special Traits

  • Surprise Attack. If the spider surprises a creature and hits it with an attack during the first round of combat, the target takes an extra 7 (2d6) damage from the attack.
  • Spider Climb. The spider can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.
  • Web Sense. While in contact with a web, the spider knows the exact location of any other creature in contact with the same web.
  • Web Walker. The spider ignores movement restrictions caused by webbing.


  • Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 7 (1d8 + 3) piercing damage and is grappled. Additionally, the target must make a DC 11 Constitution saving throw, taking 9 (2d8) poison damage on a failed save, or half as much damage on a successful one. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralyzed while poisoned in this way. Only one target can be grappled by the spider in this way.
  • Web Prey. The spider secures a creature that it has grappled or that is incapacitated that is within 5 feet. The creature is wrapped in webbing (escape DC 13) and is knocked prone and restrained. The webbing can also be attacked and destroyed (AC 10; HP 5; vulnerability to fire damage; immunity to poison, and psychic damage) but offers no cover for the victim.


  • Parry. The apocalypse knight adds 6 to its AC against one melee attack that would hit it. To do so, the knight must see the attacker and be wielding a melee weapon.
