These are the materials Xilonen requires for her Ascension. The Gold-Inscribed Secret Source Core is a drop from a boss not yet in the game, so it's not pre-farmable. But the rest can be farmed as of Genshin Impact version 5.0. To gather these materials, access to Natlan is a must.
Required Ascension materials:
Natlan local specialty: x168 Brilliant Chrysanthemum.
Sauroform Tribal Warrior drops: x18 Sentry’s Wooden Whistle, x30 Warrior’s Metal Whistle, x36 Saurian-Crowned Warrior’s Golden Whistle.
Character Ascension materials: x6 Prithiva Topaz Gemstone, x9 Prithiva Topaz Chunk, x9 Prithiva Topaz Fragment, x1 Prithiva Topaz Sliver.
Secret Source Automaton: Configuration Device: x46 Gold-Inscribed Secret Source Core.
Character EXP Materials: 420,000 Mora.
📍Locations - Where to Farm Xilonen Ascension materials:




Brilliant Chrysanthemum location:
Found in the northwest corner of Natlan. You can pick up a maximum of 71 at a time. Each one respawns two real-life days after being harvested. So, collecting all 168 will take more than two full harvests, which means four days. Or, visit other players' worlds to speed up the process. If you have at least one Brilliant Chrysanthemum in your inventory, click "Go to Collect" for easier tracking.
Where to farm Gold-Inscribed Secret Source Core: As mentioned earlier, the boss that drops this material is not in the game yet. You'll have to wait for Genshin Impact version 5.1 to farm for this crucial material.

📜Xilonen Skill Materials:
