Clockwork Spider

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

Acid Spit. Ranged Weapon Attack: +5 to hit, range 40/80 ft., one creature. Hit: 6 (1d6 + 3) piercing damage, and the target must make a DC 11 Constitution saving throw, taking 9 (2d8) acid damage on a failed save, or half as much damage 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.

Wire Webbing (take a round to reset on miss). Ranged Weapon Attack: +5 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 14 Strength check, break the webbing on a success. The webbing can also be attacked and destroyed (AC 12; hp 10; vulnerability to acid damage). Once target is restrained the clockwork spider draws the target to it on a successive contested athletics check at half the targets movement a round. Once the target is in melee of the clockwork spider there is one more contested athletics check and on a fail the target is bundled up in wire and pulled onto the clockwork's back rendering the target incapacitated.
