These “monsters” populated a Wizarding University library. I honestly can’t remember if I made the tome up or found it. Other potential library encounters included a lost research student, a Gelatinous Cube who acted as official library cleaner, a discarded backpack containing spell scrolls and a cloak, and a lizard stuck inside a ring of Magic Missile.

Book swarm

A swarm of flitting, angry magic tomes

The swarm can occupy another creature’s space and vice versa, and the swarm can move through any opening large enough for a book. The swarm can’t regain hit points or gain temporary hit points.

Actions:

Paper Cuts. Melee Weapon Attack: +4 to hit, reach 5 ft., one target in the swarm's space. Hit: 7 (2d6) piercing damage, or 3 (1d6) piercing damage if the swarm has half of its hit points or fewer.
