Target LV220 and above

The phantom tome that revealed itself within the Dimensional Rift, the 'Battlefield Textbook'. The moment you set foot in that book, another Prontera unfolds before your eyes. There, you will come face to face with Valkyries who repeat endless battles.

The Valkyries say: Only those who fight endlessly and prove themselves can reach true glory. Rumors already circulate of those who have obtained treasures unlike any other in this world, deep within this book.

Now the choice is yours.

Throw yourself into fierce battle, and prove your limits. And at the end of it, seize a new treasure.

✦ Invaded Prontera ✦

Prontera, reduced to ruins amid an unknown history. This city, destroyed by a long war that has continued for ages, has been chosen by the Valkyries as an infinite battlefield to prove the qualifications of a warrior. The howls of the spirits who lost their lives in the brutal war echo throughout the city.
