CREATURE 16Female jorogumo
Appearing as beautiful, well-dressed humans, jorogumo lurk in the high mountains and prey on travelers. These evil creatures can fully change into a giant spider or sprout spider legs from their backs, and they often keep giant spiders as pets. Jorogumo usually eat their prey, but some humanoids meet an even more gruesome fate as living incubators for jorogumo eggs. Though most jorogumos are solitary creatures, some have taken up worship of Norgorber and serve as valuable allies to thieves' guilds following that god's guise as the Gray Master.
A constant spell affects the monster without the monster needing to cast it, and its duration is unlimited. If a constant spell gets counteracted, the monster can reactivate it by spending the normal spellcasting actions the spell requires.
The jorogumo takes on the appearance of any Small or Medium spider. This doesn't change their Speed or Strikes.
The monster changes its shape indefinitely. It can use this action again to return to its natural shape or adopt a new shape. Unless otherwise noted, a monster cannot use Change Shape to appear as a specific individual. Using Change Shape counts as creating a disguise for the Impersonate use of Deception. The monster's transformation automatically defeats Perception DCs to determine whether the creature is a member of the ancestry or creature type into which it transformed, and it gains a +4 status bonus to its Deception DC to prevent others from seeing through its disguise. Change Shape abilities specify what shapes the monster can adopt. The monster doesn't gain any special abilities of the new shape, only its physical form. For example, in each shape, it replaces its normal Speeds and Strikes, and might potentially change its senses or size. Any changes are listed in its stat block.
A creature hit by the jorogumo's web attack is Immobilized and stuck to the nearest surface, preventing the creature from moving.
The DC to Escape or Force Open the web trap is 37.
