Farming Genshin Impact’s Handguards without routes can be one of the hardest and most exhausting activities in developer HoYoverse’s RPG. The Ascension Material is, after all, used by many powerful and popular playable characters, so players will likely need many of them. Those who want to ascend Wanderer, Raiden Shogun, Ayaka Kamisato, and Yae Miko to level 90 will have to have plenty of these at hand. Additionally, the mentioned characters and the Electro Traveler use Handguards for Talent Ascension, meaning more of these items will be required to max each of these characters out.
