Kingdom Hearts 2.8 has 51 objectives, and this guide focuses purely on number 29. The task is to find the seven brightest gems in the mines where the Seven Dwarves work. All of these shiny valuables are in the World Within, so let’s get started.
Gem 1 : Head down the long path to the mines. You’ll see the first mirror straight ahead. The gem is on a rock to the left of the mirror.
Gem 2 : Complete the first mirror puzzle by interacting with it. Jump on the platforms you make. To the left of the second mirror is gem 2.
Gem 3 : Interact with the second mirror when you see the platform lined up to its lowest point. The platform that spawns will bring you to gem 3.
Gem 4 : Go back to the second mirror and complete the puzzle by raising the pillar that was just lowered to get Gem 2. On the long path you’ll come to a cluster of boxes. Inside them is Gem 4.
Gem 5 : Complete the mirror puzzle on the end of the path by lining up the hued dots so they create a star. This brings you to an arena where you’ll fight lots of Heartless. To your immediate left is a bunch of boxes. Smash them to find Gem 5. You just completed Objective 30 too!
Gem 6 : Further into that same arena, you’ll see a pillar standing on its side. To the left of that is a rock with the gem.
Gem 7 : Slide down the path on the other end of the arena and you’ll come to a mirror. Activate it. Now that you know what gems look like, you should see one in the left side of the reflection. Tap triangle at the moment the platform passes through it.
That’s all there is to it. Be sure to check out our full Objectives list for guides and tips for completing the rest. If you’re having trouble with a boss, you can check out our boss guide too.
