Keen Senses. The thylvestris has advantage on Wisdom (Perception) checks that rely on smell, sight, or hearing.

Spider Climb. The thylvestris 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 thylvestris knows the exact location of any other creature in contact with the same web.

Web Walker. The thylvestris ignores movement restrictions caused by webbing.

Grappler. The thylvestris has advantage on athletics checks made to grapple an opponent.

Silken Embrace. A target successfully grappled by a thylvestris is almost immediately wrapped within layers of spider silk. A medium creature is nearly instantaneously rendered helpless, but every size category above medium requires an additional turn of uninterrupted grappling to fully restrain. A creature larger than size Huge is immune to this effect. When fully restrained, a creature is rendered incapacitated and restrained. A creature wrapped in this manner automatically fails any contested grapple check. At the end of each of the creature's turns, they can make a DC 18 strength saving throw to break free of the bindings, though this does not break free of a grapple. Every turn spent grappled by a thylvestris after the first turn wrapped in this way sees the DC for the save increase by +3 every turn, with a maximum of DC 27.

Actions

Multiattack: The thylvestris can use pounce if it is available and is not currently grappling a creature. It can then use its claw twice and bite or web once.

Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one creature. Hit: (1d8+4) piercing damage plus (4d8+8) poison damage. The target must succeed on a DC 17 Constitution saving throw or take the poison damage. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 4 hours, even after regaining hit points, and is paralyzed while poisoned in this way.

Claws. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: (2d4+2) slashing damage.

Pounce (Recharge 4-6). If the thylvestris moves at least 20 ft. straight toward a creature and then hits it with a claw attack on the same turn, that target must succeed on a DC 17 Strength saving throw or be knocked prone. If the target is prone, the thylvestris can make one grapple action against it as a bonus action.

Web (Recharge 5-6). Ranged Weapon Attack: +7 to hit, reach 45/75 ft., one creature. The target is restrained by webbing As an action, the restrained target can make a DC 16 Strength check, bursting the webbing on a success.
