New The Boss Challenge is a mode added in Ocarina of Time 3D. It lets you refight the dungeon bosses you have already beaten, against the clock, and once you've beaten them all it unlocks the Boss Gauntlet, a back-to-back run through every boss.
Finish the Forest Temple and return to the Temple of Time, where Sheik mentions that you can now go home to Kokiri Forest. Walk up to Link's bed and choose to sleep. A menu lets you pick any boss you have defeated. Sleeping also refills your health.
After the Shadow Temple and the Spirit Temple, defeat every boss in the Boss Challenge once more to unlock the Gauntlet. You fight all eight bosses in a row, starting against Gohma with five Heart Containers, and the total time is recorded. You can only heal between fights with what's in your bottles.
After each boss you choose one of two treasure chests, a small one and a large one. Each gives a random reward from a set that depends on the boss:
| After | Small chest can hold | Large chest can hold |
|---|---|---|
| Gohma | Bombs | 10 Deku Nuts, 30 Deku Seeds or Deku Sticks |
| King Dodongo | A Bottle, a Heart Container or a Recovery Heart | A Bottle, 10 Deku Nuts, Deku Sticks or a Recovery Heart |
| Barinade | A Bottle or a Heart Container | A Bottle, Deku Nuts or a Recovery Heart |
| Phantom Ganon | Big Quiver, a Bottle or the Longshot | Giant's Knife, a Heart Container or a Recovery Heart |
| Volvagia | Big Quiver, Green Potion, Hover Boots, Iron Boots or the Longshot | Blue Potion or a Recovery Heart |
| Morpha | Big Quiver, Blue or Green Potion, a Heart Container, Hover Boots or a Recovery Heart | Arrows, a Poe Soul or a Recovery Heart |
| Bongo Bongo | A Heart Container or a Red Potion | Deku Nuts |
Master Quest has its own Boss Challenge, and it is much harder. Bosses deal double damage, you start child-era fights with three Heart Containers and adult-era fights with five, and you can't recover health at all except with potions you find in chests or pots. In the Master Quest Gauntlet you get only three Heart Containers for the whole run, though the reward chests can hold more.
