Gather your courage (and your Ingots), for the Year Beast has come! For the next 24 hours, youll be able to turn the terror of the Year Beast into the treasures of the New Bloom Festival. Yet facing the beast is not a challenge to be taken lightly. To prepare, we strongly suggest gathering a group of friends, then entering Year Beast Practice to learn about the new weapons at your disposal and to sharpen your strategies. Once you think youre ready, choose „Fight the Beast“ to enter the real battle, where youll spend your hard-earned Ingots to equip your chosen hero.
Each Ingot translates to 40 in-game gold for you to use to purchase equipment and fireworks, as well as using buyback should you expire. Once youre equipped, start the fight and deal as much damage to the Year Beast as you can. The more damage you deal, the higher youll rank, and the better your loot will be. After the Year Beast departs, players from groups who dealt damage in the top 10% will each receive the illusive Redhoof courier, and those who earn their way into the top 1% will earn the coveted Jadehoof courier!
