Innate Spellcasting. The jorogumo's innate spellcasting ability is Wisdom (spell save DC 15). The jorogumo can innately cast the following spells, requiring no material components:
Spider Climb. The jorogumo 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 jorogumo knows the exact location of any other creature in contact with the same web. Web Walker. The jorogumo ignores movement restrictions caused by webbing.
Multiattack. The jorogumo makes three attacks, one bite attack, and two tarsus attacks. Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one creature. Hit: 4 1d4+2 piercing damage plus 9 2d8 poison damage. Tarsus (Spider Form). Melee Weapon Attack: +6 to hit, reach 10 ft., one creature. Hit: 9 2d6+2 piercing damage. Web (Recharge 5–6). Ranged Weapon Attack: +7 to hit, range 30/60 ft., one creature. Hit: The target is restrained by webbing. As an action, the restrained target can make a DC 12 Strength check, bursting the webbing on a success. The webbing can also be attacked and destroyed (AC 10; hp 5; vulnerability to fire damage; immunity to bludgeoning, poison, and psychic damage). Change Shape. The jorogumo magically polymorphs into a Medium female humanoid, or back into its true form. It's statistics are the same in each form. Any equipment it is wearing or carrying isn't transformed. It reverts to its true form if it dies.
