Reaching the ultimate conclusion of Pokemon Legends: Arceus requires trainers to prove their dedication by completing the Hisui Pokedex. Facing the titular mythical Pokemon is the final test of skill and patience in the entire game. Understanding the exact prerequisites and preparation steps ensures you can successfully trigger this historic encounter and complete your journey.
Completing the Hisui Pokedex Prerequisites
Before you can initiate the encounter with Arceus, you must catch every single Pokemon available in the Hisui region. This requirement means registering 237 standard entries in your Pokedex, excluding event-exclusive mythical Pokemon like Darkrai and Shaymin. You do not need to reach research level 10 for each entry, but every creature must be officially captured.
Tracking down rare spawns, distortion-exclusive Pokemon, and spiritomb fragments represents the most time-consuming phase of this challenge. Utilizing trading options in Jubilife Village can help fill frustrating gaps in your regional collection. Staying organized as you explore each zone prevents unnecessary backtracking later in your playthrough.
Initiating Request 102 at the Temple of Sinnoh
Once your Pokedex contains all necessary entries, return to Jubilife Village to receive main story Request 102. This mission directs you back to the Summit Camp in the Coronet Highlands. From there, travel up to the Temple of Sinnoh where your initial journey through space and time reached its climax.
Standing on the central platform inside the temple triggers a prompt to play the Azure Flute. Playing the flute creates a glowing staircase leading upward to the Temple Above. Ascending these celestial stairs brings you face-to-face with Arceus in a divine arena high above Hisui.
Mastering the Arceus Boss Battle Mechanics
The encounter with Arceus functions as an action-heavy action battle similar to noble Pokemon encounters. Arceus attacks with rapid energy beams, expanding shockwaves, and area-of-effect meteor strikes that require precise dodging. Learning the visual cues for each attack pattern is essential for maintaining your stamina bar during the fight.
When Arceus begins charging a massive area attack, throw balm items continuously to interrupt its focus and create a vulnerability window. Throwing a partner Pokemon during this stunned phase initiates a standard turn-based battle. Winning the turn-based segment temporarily dazes the boss, allowing you to land numerous balm hits quickly.
Claiming Your Ultimate Reward
Depleting Arceus's frenzy gauge completely finishes the battle and automatically awards you the mythical Pokemon. Unlike standard encounters, you do not need to throw a Pokeball to capture it successfully. Arceus joins your team automatically along with the Legend Plate, a powerful key item that dynamically alters its typing in battle.
Capturing Arceus officially unlocks the final main story cinematic and completes the grand arc of the game. Having Arceus in your roster provides unmatched versatility for endgame battles and rematches. Taking the time to fulfill all regional requirements rewards players with one of the most memorable achievements in Pokemon history.
