Where To Find Arataki Itto's Ascension And Talent Materials

Genshin Impact Primo Geovishap Prithiva Topaz

Prithiva Topaz Slivers, Fragments, Chunks, and Gemstones can be earned from daily commissions, certain quests, and the following bosses.

  • Normal Bosses
    • Geo Hypostasis
    • Golden Wolflord
    • Primo Geovishap
    • Perpetual Mechanical Array
    • Ruin Serpent
  • Weekly Bosses
    • Azhdaha
    • Andrius

The most efficient boss to farm for Itto's materials is the Golden Wolflord, as this boss will drop Prithiva Topaz materials and Riftborn Regalia. If you've obtained all the Riftborn Regalia you need, the Geo Hypostasis and Ruin Serpent are the second-best options.

Onikabuto

Onikabuto can be found around Inazuma's archipelago. These are the little purple beetles you see on trees. They like to hang out in areas with high levels of Electro energy, like near the Mikage Furnace.

Slime Condensate, Secretions, and Concentrate

These common items can be gathered by defeating slime enemies around Teyvat. These enemies are extremely common and appear in all corners of the world, so chances are you already have a ton of these items stocked up.

Riftborn Regalia

Genshin Impact golden wolflord boss

As mentioned above, Riftborn Regalia is a boss material that drops from the Golden Wolflord boss. This boss can be found on Tsurumi Island near Inazuma, and will cost 40 Original Resin to obtain its rewards.

Teachings, Guides, and Philosophies of Elegance

Arataki Itto's talent books can be obtained from the Violet Court Domain on Tuesday, Friday, and Sunday. We recommend bringing high-damage Electro characters to quickly clear out this domain.

Ashen Heart

La Signora Crimson Witch Of Flames Boss Fight

Ashen Heart is a drop from the La Signora weekly boss fight in Inazuma. Come back each week for a chance to get this boss item, or use Dream Solvent to convert other La Signora items into Ashen Hearts.

Crown of Insight

Finally, to upgrade Arataki Itto's talents to level 10, you'll need a Crown of Insight. This rare item can only be obtained from time-limited events, or from the Sacred Sakura, Frostbearing Tree, and Lumenstone Adjuvant offerings.
