False Appearance. While the paper golem swarm remains motionless, it is indistinguishable from ordinary sheets of paper.
Immutable Form. The paper golem swarm is immune to any spell or effect that would alter its form.
Ink Blot (Recharge 4-6). As a bonus action, the paper golem applies ink to itself. The next time it hits a creature with a paper cut attack or whirlwind action, the creature must make a DC 13 Constitution saving throw, taking 5 (2d4) poison damage on a failed save, or half as much damage on a successful one.
Magic Weapons. The paper golem's weapon attacks are magical.
Swarm. The swarm can occupy another creature's space and vice versa, and it can move through any opening large enough for a piece of paper. The swarm can't regain hp or gain temporary hp.
Paper Cut. Melee Weapon Attack: +5 to hit, reach 0 ft., one creature in the swarm's space. Hit: 14 (4d6) slashing damage, or 7 (2d6) slashing damage if the swarm has half of its hp or fewer.
Whirlwind (Recharge 5-6). The air is momentarily filled with paper golems. Each creature within 5 feet of the swarm must make a DC 13 Dexterity saving throw, taking 7 (2d6) slashing damage on a failed save, or half as much damage on a successful one.
