Hit : 18 (4d8) slashing damage, or 8 (2d4 + 3) slashing damage if the swarm has half of its  hp  or fewer.

Ranged Weapon Attack : +7 to hit, range 20/60 ft., one target.  Hit : 18 (4d8) piercing damage, or 8 (2d4 + 3) piercing damage if the swarm has half of its  hp  or fewer.

The swarm calls out in synchronous, tiny voices before chopping away at the feet of one creature in the swarm\xe2\x80\x99s space. The target must succeed on a DC 15  Strength  saving throw or be forced  prone . If the target is forced  prone , the swarm can then make one Go for the Knees  attack  against it as a bonus action. \n'b'\n'b' ABOUT \n'b' The forgotten tome cracked open and out sprang a throng of tiny, colorful people; illustrations come to life. \n'b' Gryllus, also known as marginites, are manuscript illustrations brought to life through transmutation rituals. A singular gryllus is little more than a tiny armless humanoid with a costume and prop, often a caricature of a profession, such as baker or guard. \n'b' But an entire tome\xe2\x80\x99s worth of gryllus forms a teeming swarm with a unified purpose, usually a compulsion to defend the book where they are found. \n'b'  Secret Guardians . Wizards and other masters of arcana create swarms of gryllus to protect their precious spellbooks and esoterica. Religious and secret orders who lack the knowledge of their creation pay handsomely to have holy texts embellished with gryllus protection. Swarms of gryllus created this way often judge their book\xe2\x80\x99s readers, praising the worthy and annoying any undesirables who browse through their pages.'
