As you start upgrading your town in Eiyuden Chronicle, many of the Drafting Studio Town Development nodes will start requiring Mystic Lumber. However, it isn’t until after you get through the Proving Ground dungeon and head toward Euchrisse that you’ll start to be able to find it.
Where do I find Mystic Lumber in Eiyuden Chronicle?
Like Lumber, Mystic Lumber is a material you get from gathering at the glittering tree spawn points that tend to appear in forest dungeon spaces. To collect it, you approach the tree and press the action button. From my experience, you’ll always get two Mystic Lumber from one of these gathering points without any sort of special support character like Kerrin present to increase your yield.
Early on, I’ve found two reliable sources. The first is the Dappled Forest, which is right near your castle town and the place where you’ll recruit Kerrin. While initially you are limited to the first part of the woods, once you finish the Proving Grounds, and reunite with old friends in Hishahn, you should be able to return to that forest and proceed into the second part of it. (The third part will still be off limits for the time being.)
The second is The Greatwood-South. This is the part of the dungeons directly between The Treefolk Village and the Euchrisse overworld map. There’s one tree gathering spot I’ve found gives Mystic Lumber every time I go to it. You can find it at the location I highlighted in the map screenshot below.
