Salvage Ancestral items for a chance at Scrolls of Restoration, and invest in the Trash for Treasure path to increase scroll income in Diablo 4 Season 16. Greater Temper consumes 30 scrolls and 1,000 Obducite per upgrade at the listed test cost. While farming supplies remains the direct route, some players consider D4 Gold for other gear costs; gold does not replace the recipe materials.

Unlock the recipe before spending scrolls

Greater Temper is a Horadric Cube recipe that upgrades an existing Tempered Affix into a Greater Affix. It guarantees that upgrade, so players can avoid repeatedly restoring and tempering an item while chasing the stronger result.

Open Tyrael's Boons and follow the Trash for Treasure path to Magic in the Metal. The unlock takes four points in that path, and the system is available to seasonal characters without the Lord of Hatred expansion.

The 30-scroll and 1,000-Obducite cost comes from the 3.3.0 test period and could change. Check the recipe in game before committing your materials.

Farm scrolls and choose the right item

Salvaging Ancestral items gives you a chance to receive a Scroll of Restoration; a scroll is not guaranteed from every item. The first Trash for Treasure path also increases scroll and Obducite income, making it a useful early investment for this recipe.

Open Tyrael's Boons, select Trash for Treasure, and spend the required points to unlock Magic in the Metal.
Collect Ancestral items and salvage them at the blacksmith to build your scroll supply. Keep useful gear that may serve as an upgrade target.
Choose an item you expect to keep into the endgame. Apply the desired Tempered Affix at the blacksmith before using the cube recipe.
Open the Horadric Cube and select Greater Temper. Check the displayed material cost and the selected item before confirming.
Inspect the resulting item and confirm that the chosen Tempered Affix is now a Greater Affix. Its other affixes should remain unchanged.

Start with a weapon carrying a strong offensive temper. A two-handed weapon or an off-hand item holding a key build multiplier can also be a priority, depending on your setup. Save scrolls for two or three durable pieces instead of spending them on gear you expect to replace soon.

Protect your gold and materials

Five upgrades at the listed cost require 150 scrolls and 5,000 Obducite; ten require 300 scrolls and 10,000 Obducite. Scrolls can become the limiting resource, so salvage decisions matter as much as collecting Obducite.

The recipe improves an existing Tempered Affix only. It cannot promote a base stat or implicit line, and it cannot repair a weak base affix. Check those lines first; an otherwise strong item may still need an enchanting reroll at the occultist.

Manual tempering can consume scrolls and repeated blacksmith fees without producing the desired result. Greater Temper has a fixed listed material cost and guarantees the upgrade, but it does not remove the gold needed for masterworking, enchanting, or changing boon points. Canceling a Tyrael's Boons point costs 5,000,000 gold, so plan your early path before committing.

For your next upgrade, inspect your weapon and compare its existing affixes with the Diablo 4 Items you are considering, then save your scrolls until you have a piece worth keeping and can verify the Greater Temper cost in the cube.
