Keen Smell. The bebilith has advantage on Wisdom (Perception) checks that rely on smell.
Spider Climb. The bebilith 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 bebilith knows the exact location of any other creature in contact with the same web.
Web Walker. The bebilith ignores movement restrictions caused by webbing.
Actions
Multiattack. The bebilith makes three attacks: two with its claws and one with its bite. If both claw attacks hit one target, the target’s armor or natural armor (if any) takes a permanent and cumulative −1 penalty to the AC it offers (to a minimum of 10 before other modifiers). Armor reduced to an AC of 10 is destroyed.
Bite. Melee Weapon Attack: +11 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 7) piercing damage, and the target must succeed on a DC 18 Constitution saving throw or take 17 (5d6) radiant damage. At the end of each of its turns, the creature must make another save, ending the effect on a success or taking 17 (5d6) radiant damage on a failure. If a creature dies while under this effect, the body ignites and burns until destroyed or targeted with bless, dispel evil and good, or similar magic.
Claw. Melee Weapon Attack: +11 to hit, reach 10 ft., one target. Hit: 12 (2d4 + 7) slashing damage.
Web (Recharge 5–6). Ranged Weapon Attack: +11 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 18 Strength check, bursting the webbing on a success. The webbing can also be attacked and destroyed (AC 10; hp 5; resistance to fire damage; immunity to bludgeoning, poison, and psychic damage).
