Location & trigger
Craft the entry item for the boss you intend to challenge. Key of Terror, Soul of Hatred, Ankh of Eternal Death and Signet of Existence have different material recipes and lead to different encounters. Crafting a key is not rolling the boss’s equipment pool.
Inputs & operating steps
Key of Terror needs one material from each of the first six Act bosses. Soul of Hatred needs three each of Soul of Anguish, Soul of Despair and Soul of Corruption. Signet of Existence needs one fragment from each of Acts 1–7 and is used on Inferno.
How this source differs
The boss-entry tool compares material costs and consumed entry quantities. Some encounters instead use collected fragments, dungeon keys or a Codex, so do not assume every boss has a Crafting Cube key recipe.
