Ever since the original Kingdom Hearts, fans of the franchise have been collecting crafting materials and creating all sorts of powerful weapons to wield during their adventures, and Kingdom Hearts 3 is no different. One of the most powerful weapons in Kingdom Hearts 3 is the Ultima Weapon, which requires seven Orichalcum+ materials to craft, and collecting all the necessary Orichalcum+ is no easy task.

One way that players can get a piece of Orichalcum+ is by collecting all 10 treasures on the Frozen "slider." To start this mini-game, Kingdom Hearts 3 players first need to complete the Arendelle world and then return to the North Mountain area. Players will find various Frozen characters congregated here, including Elsa, so chat with her to start the Frozen slider mini-game.

In the Frozen slider mini-game, Sora, Donald, and Goofy all hop on Goofy's shield, aka the Trinity Sled, and go sledding down a mountain. There are treasures hidden along the way, and collecting all 10 of them will reward players with the Orichalcum+. Players don't have to get all 10 treasures in a single go (and in fact, that appears to be impossible), but they will have to actually finish the mini-game for it to save the treasures they've already collected.

We recommend using the above video guide by YouTuber Everglow to help find all of the Frozen slider treasures. Due to the layout of the mountain, it's virtually impossible to provide an accurate text guide as the environment largely looks the same. It's just a big mountain full of snow and trees after all, and so looking for the treasures without a video guide would be confusing.

Once Kingdom Hearts 3 players manage to collect all of the Frozen slider treasures, they will be rewarded with Orichalcum+, though they will need seven pieces of it in total if they hope to craft the Ultima Weapon. However, considering how powerful the Ultima Weapon is, it's definitely worth the trouble.

Kingdom Hearts 3 is out now for PS4 and Xbox One.
