The Trial of the Sword is a location from The Legend of Zelda: Breath of the Wild. It is a cave unlocked during the side quest "EX Trial of the Sword" from "The Master Trials" DLC pack installation. When Link approaches the Master Sword pedestal at Korok Forest, the Great Deku Tree asks him to place the sword back in its pedestal to awaken its true splendor and to face the trial.
In this location, enemies appear one after another inside forty five total rooms, and Link starts without any weapons or armor. All the enemies of each room must be defeated to access the next room. After clearing this trial, the true power of the Master Sword awakens and always remains in its glowing state. Any enemies that are fought in this dungeon do not drop any of their normal spoils as opposed to being encountered outside. Any section that has been completed previously can be revisited, however the same rules still apply as in the first visit.
There are rest areas within the sections of the Trial with weaponry, various restoration items, cooking pots, and ingredients for recipes; the "Beginning Trials" section has one at the seventh floor, there are two within the "Middle Trials" section, floors five and eleven, and the "Final Trials" section has three for floors six, twelve, and eighteen.
In early builds of the DLC pack, this location was named "Cave of Trials Challenge".
