Holler Spider

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

Vigilant. If the holler spider remains motionless for at least 1 minute, it has advantage on Wisdom (Perception) checks and Dexterity (Stealth) checks.

Bite. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 4 (1d4 + 2) piercing damage.

Hoot. Ranged Weapon Attack: +4 to hit, range 20/60 ft., one target. Hit: 5 (1d6 + 2) thunder damage. If the holler spider scores a critical hit, it is pushed 5 feet away from the target.

Distressed Discharge (Recharge 5-6). The holler spider releases a short, distressed cacophony in a 15-foot cone. Each creature in the area must make a DC 12 Constitution saving throw, taking 5 (2d4) thunder damage on a failed save, or half as much damage on a successful one. The holler spider is pushed 15 feet in the opposite direction of the cone.

Sound Alarm. When the holler spider detects a creature within 60 feet of it, the spider can emit a hoot or trumpet audible within 300 feet of it. The noise continues until the creature moves out of range, the spider's handler uses an action to soothe it, or the spider ends the alarm (no action required).
