Monster Manual III
Appropriately, web golems can utilize many of the same tactics that a giant spider would. They are usually posted high on the ceiling, nestled among other spider webs, waiting for intruders.
Adhesive (Ex): The webbing that makes up a web golem is extremely sticky. A web golem automatically grapples any creature it hits with a slam attack. Such creatures cannot get free while the web golem functions without removing the web adhesive first. A web golem makes a free bite attack against any creature it grapples each round. While it grapples a creature, it can use its normal attack to deal bite or slam damage to the grappled creature, or it can attempt to attack another creature with a bite or slam attack. The web golem cannot grapple more than one creature at a time.
Fire or acid damage causes the web golem's adhesive ability to stop functioning for 1d4 rounds. When the web golem's adhesive ability fails, foes already grappled by a web golem can escape from the grapple normally (with a successful grapple or Escape Artist check). A web golem can release a grappled creature normally or not grapple a foe it strikes if it wishes.
Construct: Immune to mind-influencing effects, poison, disease, and similar effects. Not subject to critical hits, subdual damage, ability damage, energy drain, or death from massive damage.
Fire Vulnerability (Ex): A web golem takes double damage from fire attacks unless a save is allowed for half damage. A successful save halves the damage, and a failure doubles it.
Magic Immunity (Ex): A web golem is immune to all spells, spell-like abilities, and supernatural effects, except as follows. A grease spell slows it (as the slow spell) for 2d6 rounds, with no saving throw. While within the area of a web spell, a web golem gains fast healing 5.
Poison (Ex): Bite, Fortitude save (DC 14); initial and secondary damage 1d6 Strength.
