Hero's Trial

The is a stage in.

Entrance to the Realm
The FS: appears once either five NaN Medal of Courages or 30,000 total NaN Rupees have been obtained. Initially a rock spire on the eastern coast of FS:, lightning strikes the area to reveal a sword-like structure.

Like FS:, the FS: entrance has three color-coded doors. However, each door has a unique set of non-randomized levels. Initially, only the silver and golden doors are visible, and the silver door must be completed first.

Once the golden door has been completed, a shutter will open to reveal the third and final door.

Themes and Navigation
The FS: is themed on alternate versions of each of the four main NaN Stages. The door levels are based on FS:, FS:, and FS:, respectively, with every door's third and final level being an alternate version of FS:.

The levels are longer and significantly more difficult than all other NaN Stages, though they do not contain NaN Bosss. To commemorate the series's 25th anniversary, a "25" design is also worked into areas of certain levels. For example, one of the Talus Cave levels includes a set of panels viewable only by Green Link and a set of panels viewable only by Red Link, which together form the number "25."

Rewards
Link will gain the ability to use the Hurricane Spin after completing all three levels. It can be used anytime during solo or multiplayer gameplay.
