Catching the Legendary mascot Zacian is one of the ultimate achievements for trainers exploring the Galar region in Pokemon Sword. Wielding its signature blade in its mouth, this powerful Fairy and Steel-type creature is a highly sought-after combat asset for both the main story and the competitive post-game scene. However, securing this magnificent beast requires patience as it cannot be officially captured until after you defeat the Champion Leon and complete a specific set of endgame quests.

Complete the Main Story and Post Game Quest

Before you can initiate the true battle against this Legendary entity, you must successfully claim the title of Galar Champion by conquering the regional tournament. Once the initial credits roll, your journey continues as you return to the Slumbering Weald to meet up with your rival Hop. Following a sequence of events involving the brothers Sordward and Shielbert, you will follow a trail across multiple stadiums to restore peace to the region.

This extensive tracking mission eventually leads you to the summit of the Energy Plant located in Wyndon. At the peak of the tower, you will encounter the mascot creature driven into a state of absolute fury by the disruptive experimental energy. You must defeat it in a challenging boss battle first, which sets the stage for the true capture sequence immediately afterward.

Prepare Your Team and Inventory for Battle

Facing a level 70 Legendary warrior requires careful strategic preparation to avoid whittling down your own team completely. Stocking up on a vast assortment of Ultra Balls, Dusk Balls, and Timer Balls will significantly increase your success metrics during prolonged encounters. Bringing along a specialized Pokemon that can inflict helpful status conditions like Sleep or Paralysis will make the catch rate much more manageable.

It is highly recommended to lead with a sturdy tank capable of resisting powerful physical Steel and Fairy-type moves during the conflict. Carefully lowering the beast's health into the red zone without accidentally knocking it out is critical for your inventory economy. Utilizing strategic moves like False Swipe ensures that the target remains at exactly one hit point, giving you the best mathematical odds for each throw.

Execute the Capture at the Energy Plant Tower Summit

Once the battle begins at the Energy Plant summit, focus entirely on mitigating the immediate damage from its aggressive offensive movesets. Take your time to safely reduce its health bar while sustaining your active team members with restorative potions. Once its status condition is locked in and its health remains low, begin launching your preferred selection of capturing devices.

If the encounter drags on for more than ten turns, switching exclusively to Timer Balls provides a massive boost to your overall catch efficiency. Remember that this is a static encounter, allowing you to carefully plan every single action without any rush. Once the capturing sequence concludes successfully, this legendary warrior will officially join your roster to dominate future Galar battles.
