The Riku’s Workshop scenario quest in Xenoblade Chronicles 3 Future Redeemed is unlock as part of the story during Chapter 3. For this quest, Riku needs help constructing his workshop.
First, head on over to the old house near the Colony 9 Front Gate. Once there, Riku will task you with collecting Ravamantine at Exile Fortress Ruins and a hammer from Colony 9’s storage area.
The Exile Fortress can be found in the Aurora Shelf, just northeast of the Pioneer’s Point. Once there, you’ll need to fight 9 Lv. 22 Amina Igna and Lv. 23 Wickt Igna. After defeating the large group, interact with the Ravamantine to obtain it!
Next, travel to the northwestern corner of Colony 9 to find the Storage Area. As you approach, Carrom will ask if you’re looking for something and you’ll reply that you are indeed. Afterwards, travel to the Ether Light landmark in Colony 9’s Central Plaza and speak with the Supply Manager. Your search will then take you around Central Plaza. You’ll find in next to the white tent on the southeastern side.
Once you’ve collected the Ultimate Hammer as well, return to Riku’s house. Riku’s workshop will then be ready and you can upgrade your weapons now! Riku will give you a Trail Bladestone. Interact with the anvil and upgrade Matthew’s weapon. The quest will then complete. As a reward, you’ll receive 1160 EXP, 1360 G, 4 Bladestone Fragments and 2 Bladestones.
