Level 9

, also stylized as Level-9, and known as Death Mountain, is the ninth and final Dungeon in.

Entrance
In the First Quest, Death Mountain is found by Bombing the western peak of Spectacle Rock.

In the Second Quest, it is found by Bombing the northern wall of the very narrow passageway found at the northwesternmost area of the game.

First Quest
In the First Quest, Level-9 is shaped like a skull. It is the largest Dungeon in the First Quest, containing over 50 rooms. An Old Man waits at the entrance of Level-9, preventing any who do not possess a the complete Triforce of Wisdom from entering. Therefore, Link must have obtained all eight Triforce Fragments from the other eight Dungeons in order to enter Level-9. Link must fight his way through swarms of enemies, including hordes of dangerous Wizzrobes, groups of deadly Lanmolas and several mini-bosses known as Patras. Ganon is the Boss of the Dungeon and the final Boss of the game. Level-9 contains two main Items. One of them is the Red Ring, which reduces Link's damage taken to a quarter of the normal amount as opposed to the Blue Ring that halves damage. The other Item is the legendary Silver Arrow that Link must use to vanquish Ganon. Once Ganon is defeated, Link will find Princess Zelda in the final room and the game will be complete.

Second Quest
Unlike most Second Quest Dungeons, it is very similar to its First Quest counterpart. Like in the First Quest, the main Items of the Dungeon are the Red Ring and the Silver Arrows. Ganon is the final Boss in Second Quest as well. However, the layout is very different. It is one of the most complex, maze-like Dungeons in the whole game, including numerous one-way passages and a seemingly impassable wall that prevents Link from reaching Ganon. In the Second Quest, the Dungeon is shaped like Ganon's head. It is the largest Dungeon in the entire game.
