How to get the Shield of the Brave in Dragon Quest 3 Remastered
The Shield of the Brave is located in the Demon King's Claw Cave, a cave northwest of Tantegel. Considering Tantegal is the town you're directed to first, this cave is only a short distance away, allowing you to obtain the Shield of the Brave at the start of your adventure.
The Demon King's Claw Cave is not particularly long, but it has a rather inconvenient setting - magic cannot be used. While this does not restrict you from using a staff, you cannot use Shuchi, Retreat, heal, or any other magical ability.
For this reason, it is recommended to bring a Rogue, Warrior, or Martial Arts Master to better deal with this setting.
Starting in the upper left corner of the tunnel, you need to immediately go east and take the first path south. Then continue east, south, and east again until you see the stairs leading to the next floor. This is the fastest route and will help you avoid most random encounters.
On level B2, you will start in the lower right corner. The structure here is simpler than the one above, so try to avoid those side rooms unless you're looking for treasure. Once you reach the stairs in the upper left corner, remember to go down and enter the final level.
Fortunately, floor B3 is very small and takes you directly into a room with several treasure chests. However, the few treasure chests in front of you are not what you are looking for. Instead, go to the left and follow this edge until you find a treasure chest at the end. Inside the treasure chest is the Shield of the Brave.
