To obtain the Dungeon Mapping standard quest in Xenoblade Chronicles 3 Future Redeemed, speak with Burrburr near the Elevator Landing Camp rest spot. For this quest, you’ll need to gather stones from 3 separate rock faces.
Follow the objectives to each location then retrieve the item there. One can be found west of the Atattra Access Elevator, another can be found north of Zalmor’s Falls (is guarded by unique enemy Lv. 13 Hilltop Chegwin) and the last is north of Pilgrims’ Rest Remains.
Once you’ve gathered all the stones, return to Burrburr so they can find the perfect location for the dungeon. Apparently, it’s going to take 100 years before the dungeon is finished! Since early access doesn’t look like it’s in store for us, our only rewards are 410 EXP, 650 Gold and 2 Bladestones.
