Liber: Spawns books. Each book has 1 hp at start, and liber has 10 hp at start. Liber only moves after all books have been destroyed. Also, liber cannot take damage before the books have been destroyed. Liber does 5x the damage of his minions. Each wave, minion damage, minion hp, and liber hp all grow exponentially. Every 5 waves, liber spawns 1 more book. Sword has 1000 hp. This will be the same for every weapon ball that fights liber. Sword only grows from hitting Liber. Books do not count for any weaponballs scaling.
Music by me! In case you were confused, this is NOT the boss fight i was talking about in a previous project.
