Genshin Impact Sandrone Pre-Farm Guide: Ascension, Talent, and Weapon Materials (6.7)

Every material the 5-star Cryo claymore Harbinger needs, plus where to gather each one before her debut.

Every material the 5-star Cryo claymore Harbinger needs, plus where to gather each one before her debut.

Sandrone arrives as a 5-star Cryo claymore character in Genshin Impact 6.7 (Luna VIII), the final patch of the Nod-Krai cycle, and she brings the new Stella Superconduct reaction with her. Almost everything she needs to reach Level 90 with maxed talents already exists in the game, so you can stockpile her upgrade materials now and slot her into a team the moment her banner goes live.

Quick answer: Start farming Vagrancy talent books at the Lightless Capital domain on Wednesday, Saturday, and Sunday, gather Drive Shafts from Landcruiser enemies in Paha Isle, collect Subdetection Units across Fontaine, and beat the Watcher: Fallen Vigil boss for Plume of the Fallen Watcher. Only the new Lunar Iron weapon drops are locked until 6.7 launches.

Sandrone ascension materials (Level 1–90)

Ascending Sandrone all the way to Level 90 costs 420,000 Mora plus four material groups. The Shivada Jade gems come from Cryo bosses, the Subdetection Unit is a Fontaine local specialty, the Drive Shafts drop from mechanical enemies, and the Plume of the Fallen Watcher is a world boss reward.

Note: Subdetection Units take two days to respawn and there is a limited number available per world, so collect them across multiple regions and rotate back as they refresh.

Sandrone talent upgrade materials

Sandrone is an on-field Cryo DPS, and most of her damage comes from her Normal Attack talent, which drives her Calculation Mode and Overclock Mode. Levelling her Normal Attack, Elemental Skill, and Elemental Burst all to 10 requires the totals below, including three Crown of Insight.

MaterialTotal needed
Mora4,957,500
Crown of Insight3
Teachings of Vagrancy9
Guide to Vagrancy63
Philosophies of Vagrancy114
Broken Drive Shaft18
Reinforced Drive Shaft66
Precision Drive Shaft93
Madman’s Restraint18

You do not have to max every talent. If you are stretched on resin, prioritise the Normal Attack first, then the Elemental Burst, and leave the Elemental Skill for last since its value is mostly mechanical.

Where to farm each Sandrone material

Most of these sources are already accessible, so you can begin building your stock right away. The table maps every material to its location and farming schedule.

MaterialSource and location
Shivada Jade Sliver / Fragment / Chunk / GemstoneCryo overworld and Trounce Domain bosses; track them in the Adventurer’s Handbook

Tip: Spend your resin on the day-gated talent books and weapon ascension materials first, since those domains only open on certain days. On off-days, run the Watcher: Fallen Vigil boss or your weekly boss, and pick up Subdetection Units passively while exploring.

What you cannot pre-farm yet

Two parts of Sandrone’s checklist are tied to content that unlocks with the new version. The Lunar Iron weapon materials only appear after the Nod-Krai map expansion goes live, so there is no way to bank them in advance. The weekly boss drop, Madman’s Restraint, is gated behind weekly resets and is fully RNG, which means you may need several weeks of clears to gather all 18.

Everything else is fair game now. If you secure the Vagrancy books, Drive Shafts, Subdetection Units, Shivada Jade gems, and Plume of the Fallen Watcher ahead of time, you will only have those two time-gated items left to chase after 6.7 lands, letting you ascend Sandrone and her claymore almost immediately and start running Stella Superconduct teams on day one.
