Clockwork Weaving Spider

Construct Nature. The weaving spider doesn't require air, food, drink, or sleep.

Immutable Form. The weaving spider is immune to any spell or effect that would alter its form.

Magic Resistance. The weaving spider has advantage on saving throws against spells and other magical effects.

Unmaking. The weaving spider's speed and its slim, sharp blade can slice cloth, leather, and paper into scraps very quickly. Whenever a weaving spider's Trimming Blade attack roll exceeds the target's Armor Class by 5 or more, the target must succeed on a DC 13 Dexterity saving throw or one nonmagical cloth, leather, or paper object on the target becomes damaged and unusable until repaired. This effect can deface or ruin clothing, backpacks, journals, and similar objects, but it can't destroy armor.

Multiattack. The clockwork weaving spider makes two Trimming Blade attacks or two Poisoned Needle Shuttle attacks.

Trimming Blade. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 8 (2d4 + 3) slashing damage.

Poisoned Needle Shuttle. Ranged Weapon Attack: +5 to hit, range 30 ft., one target. Hit: 7 (1d8 + 3) piercing damage, and the target must succeed on a DC 13 Constitution saving throw or become paralyzed for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
