Traits

Condition Immunities paralyzed, petrified, prone, restrained, stunned. The ghostwalk ends when the spider chooses to end it as a bonus action or when the spider dies

Incorporeal Movement (During Ghostwalk Only)

The ghostwalk spider can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.

Spider Climb

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

Actions

Bite

+9 to hit, reach 5 ft (1.5 m). Hit: 2d10 poison damage.

Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 16 (2d10 + 5) piercing damage plus 13 (3d8) poison damage, or half poison damage with a successful DC 15 Constitution saving throw. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned and paralyzed for 1 hour, even after regaining hit points.

While restrained in this way, the target is invisible to all creatures except ghostwalk spiders, and it has resistance to acid, cold, fire, lightning, and thunder damage. A creature restrained by Ghostly Snare can escape by using an action to make a successful DC 14 Strength check, or the webs can be attacked and destroyed (AC 10; hp 5).

The ghostwalk spider makes two bite attacks. It can make a ghostly snare attack in place of one of its bites.

GM Tips: Using Ghostwalk Spider

5 tips available

Climbing Advantage: This creature can climb at 50 ft. It can use walls and ceilings for tactical positioning. Consider using 'Spider Climb' negation or fighting in open areas without vertical surfaces.
Fire Damage Mitigation: This creature deals fire damage. Advise players to have fire resistance ready or use water-based tactics. Consider environmental fire hazards that could backfire on the creature.
