Diablo's Horn

"Diablo's horns are sharp enough to pierce and gore, though anyone so injured would be wise to pray the wound is fatal. If not, the tainted gash would fester and rot from the inside out, giving the body of the injured over to maggots and hellish parasites long before death ends the feverish agony. Diablo's whole body bristles with vicious, bony spikes. Even a relic of one of his lesser horns would be enough to cause terror."

- Lorath Nahr^(src)

Diablo's Horn (a.k.a. the Horn of Diablo) is a demonic artifact; a horn taken from Diablo himself and utilized by the Horadrim. It contains immense power, leading Lorath Nahr to wonder if said power came from Diablo's might himself, the lingering residue of his host's rightousness, however faint, or a combination of the two, similar to the synthesis that had granted the nephalem their immense power.^[1]

In-game[]

Diablo's Horn appears in Diablo II. It is an item needed in the Pandemonium Event. It is one of the 3 major keys represented by body parts of the Prime Evils, the other two being Mephisto's Brain and Baal's Eye. The horn can be acquired by defeating Lilith in the Matron's Den.

Putting the Horn along with the Brain and the Eye in the Horadric Cube in Harrogath on Hell difficulty opens a portal leading you to Uber Tristram where the ultimate challenge awaits...

Trivia[]

While not specified, it is likely that the Horadrim obtained the Horn during the Dark Exile, as in the case of his other confirmed hosts (Albrecht, Aidan, Leah), circumstances make retrieving such a horn unlikely.
