"Ahh… The lost Horadric Scroll! What a fortunate turn of events…"— Deckard Cain
The Horadric Scroll is a quest item in Act II of Diablo II. It is first found inside a golden chest, hidden within the sewers beneath Lut Gholein and guarded by Radament. Picking up the Scroll initiates The Horadric Staff (quest).
The player is tasked with showing the scroll to Deckard Cain, who, as the last living Horadrim, has the knowledge to translate the ancient Horadric Runes. The Scroll relates the story of Baal's imprisonment within Tal Rasha's Tomb and provides clues as to where the player might find the components needed for restoring an Horadric Staff.
After the dialogue with Cain, the Scroll disappears from the player's inventory.
"Ahh… The lost Horadric Scroll! What a fortunate turn of events… As the last living Horadrim, I alone have knowledge of its meaning. Now, to read the Horadric runes it bears. Hmmm… The Horadric Mages, after binding Baal within Tal Rasha, magically sealed off his Burial Chamber from the mortal realm. Those same Mages also crafted fearsome Horadric Staves and imbued them with the special power to open the Chamber’s hidden door. After nearly losing one to the thievery of a rogue sorcerer, they divided all the Horadric Staves into two parts – wooden shaft and metal headpiece – hiding them separately to safeguard them. The Horadrim foresaw our current plight and designed the hiding places to reveal themselves to worthy heroes like you. Collect both parts of a Horadric Staff and unite them using a Horadric Cube. Then, you may enter Tal Rasha’s Burial Chamber."
