A Greater Temper plan in Diablo 4 starts with a decision about gear, not a farming route. Before committing materials to Diablo IV Items (https://www.u4gm.com/diablo-4/item), separate pieces you expect to keep from upgrades that only solve a short-term problem. The best candidate is an ancestral item with useful affixes that still fits your build after your next round of upgrades. If your equipment is changing quickly, keeping resources in reserve can be more valuable than spending them immediately.
Choose the item before setting a target
Open your stash and make a short list of ancestral pieces worth considering. Look at the affixes on each item and ask what role it serves in your build. A temporary weapon may help you clear content now, but it can be a poor place to commit scarce materials if you already expect to replace it.
Give priority to pieces you would be happy to keep on the Eternal realm or use as a reference when planning for Season 16. That doesn't mean every keeper needs an attempt. If two items compete for the same resources, start with the one you are least likely to replace, then reconsider the second after seeing the result.
Check both materials and your gold reserve
The proposed budget is 30 Scrolls of Restoration and 1,000 Obducite per Greater Temper attempt. Check the cost shown in your game before setting that budget, then multiply it by the number of attempts you actually intend to make. Two attempts at those stated rates would require 60 scrolls and 2,000 Obducite, before accounting for any other expenses.
Track the two materials separately. Having 2,000 Obducite and 12 scrolls does not cover even one attempt at the stated scroll cost, so gathering more Obducite alone won't resolve the shortage. Check your gold at the same time and leave room for repairs and other expenses rather than treating every coin as available for the session.
Keep farming decisions tied to the shortage
Choose content your character can clear comfortably and run it for a set period before returning to town. This gives you a clean point to review drops, salvage unwanted gear and compare your material totals. Leave a stash tab open for new items so that a full inventory doesn't force a rushed decision about a piece you intended to keep.
Use the next run to address whichever material remains short. If scrolls are the limiting resource, choose an activity that provides them rather than continuing solely for Obducite. If Obducite is the concern, check what your available salvage yields before selling unwanted gear. The point is to close the actual gap, not to collect more of a material you already have in sufficient quantity.
Spend one attempt at a time
On the Tyrael Boons path, consider Trash for Treasure choices that support your salvage and tempering plan before cosmetic options. Avoid undoing an existing point just for this session without checking the displayed price: the draft budget puts that change at 5,000,000 gold per point, a significant expense alongside repairs and other needs.
Once the materials are ready, inspect the item and its affixes again before opening the Greater Temper window. Resolve one attempt before deciding what to do next. If you get the result you wanted, move on; if the attempt fails, reassess the next candidate instead of spending the remaining materials simply because they are available.
End the session by recording your remaining scrolls, Obducite and gold, along with the attempt results; a screenshot can make the next planning pass easier. If you decide to buy Diablo IV Items (https://www.u4gm.com/diablo-4/item), evaluate any prospective piece against the same keeper criteria before committing your saved materials. Keep the expected Season 16 timing in mind, but don't treat an unconfirmed launch date as a reason to empty your reserves.
