Each Chapter of Dragon Quest Builders provides different challenges in regards to what materials and items are rare and difficult to make. Chapter 3 is almost totally void of Wood, bar one location. This Where To Find Wood In Chapter 3 Of Dragon Quest Builders guide will show you where to find wood so you can build the Cannon.
Where To Find Wood In Chapter 3 Of Dragon Quest BuildersYou’re not able to find enough Wood to build the Colossal Coffer early on in Chapter 3 but one of the quests in Chapter 3 requires you to build a Cannon, which requires 5 pieces of Wood. There is a single chest that contains enough Wood but not enough to build the Colossal Coffer, which you can build later in the Chapter when Wood becomes more common.
The screenshot at the top of the article shows where you must go to find the chest containing the Wood. It’s literally in a direct straight line West of the village, but it’s inside the Blue Teleportal area. Keep walking with the village flag behind you on your compass and eventually you’ll reach a small group of castle structures and a gate, quite widely separated. There’s another room nearby with 3 guards but that’s not the one you want.
Search the castle structure West of that location. The chest is locked initially but just take out the guard and you’re good to go.
Update: I had a real DERP moment here. There’s actually a ton of stumps just North West after you enter the Blue Teleportal.
