Turn Resistance. Zelrapun has advantage on saving throws against any effect that turns undead.

Temptation (Males Only). All male characters that lay their eyes upon zelrapun, must make a DC 10 Wisdom saving throw, being charmed and compelled to drop their weapons on failure.

Spider Climb. Zelrapun can climb difficult surfaces, including upside down on ceilings, without needing to make an ability check.

Web Sense. While in contact with a web, zelrapun  knows the exact location of any other creature in contact with the same web.

Web Walker. Zelrapun ignores movement restrictions caused by webbing.

Host Burst. When the zelrapun dies, (1d4 - 1) Swarm of Insects (Spiders) burst out from the corpse.

Undead Fortitude. If damage reduces zelrapun to 0 hit points, it must make Constitution saving throw with a 5 + the damage taken, unless the damage is radiant or from a critical hit. On a success, zelrapun drops to 1 hit point instead.

Multi-Attack: Rapunzel makes two main attacks.

Maim. Melee Weapon Attack:  +5 to hit, reach 5 ft., one target. Hit: 8 (2d8 + 1) slashing damage.

Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 12 (1d6 + 1) Piercing damage and the target must make a DC 13 Constitution saving throw, taking 18 (4d8) poison damage on a failed save, or half as much 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.

Web (Recharge 5-6). Ranged Weapon Attack: +5 to hit, range 15/45 ft., one creature. Hit: The target is restrained by webbing. As an action, the restrained target can make a DC 14 Strength check, bursting the webbing on a success. The webbing can also be attacked and destroyed (AC 12; hp 10; vulnerability to fire damage; immunity to bludgeoning, poison and psychic damage).
