- "Some believe this eerie headgear is inspirited by a dark entity resembling the Great King of Evil himself. It's a rather rare find."
- — Phantom Ganon Skull description
The Phantom Ganon Skull is an item from The Legend of Zelda: Breath of the Wild. It is a thematic head armor inspired by the Phantom Ganon and granting Stealth Up. It is one of the three pieces of the "Phantom Ganon Armor" set along with the Phantom Ganon Armor and Greaves. It can be obtained upon "The Champions' Ballad" DLC pack 2 installation via the quest "EX Treasure: Dark Armor".
According to Misko's EX Journal, the skull and the rest of the set, alongside five other pieces of treasure, was stolen from Hyrule Castle during the Great Calamity by Misko. The armor set was hidden within the forests of Faron, with the skull specifically being hidden underwater at the Corta Lake.
When all three pieces of the Phantom Ganon set are worn together they grant the "Stal" Disguise and Bone Atk. Up set bonuses just like the upgraded "Radiant Armor" set though without having to be upgraded as the Phantom Ganon set has the set bonues automatically by default. As a result it is a convenient alternative to the "Radiant Armor" set which must be purchased at the Gerudo Secret Club in Gerudo Town and upgraded.
Additionally like the "Radiant" and "Tingle" sets, the Phantom Ganon set will cause NPCs to react frightened or defensive around Link while wearing the set due to his monstrous appearance though react normally if spoken to.
