In the Diablo 4 PTR, Curious Addition gives you more item rolls for your Obols, with a chance of a second item, while Premium Purveyor costs more for higher Ancestral odds. It suits players who need several possible upgrades and want to compare their options; you can also browse Diablo 4 Items for gear that fits your plans. Neither vendor path promises a useful result on every purchase.
1 How Curious Addition Works in Diablo 4
Curious Addition is a separate choice within the Purveyor interface, alongside the existing purchase path. Select its label and check the price for the slot you want before committing Obols.
Its Two for One description offers up to a 25% chance of receiving a second item from an eligible purchase. That figure is a ceiling, not a promise that every purchase uses the maximum chance or produces an extra item.
Premium Purveyor serves a different purpose: its purchases cost three times as much for higher Ancestral odds. Curious Addition favors a larger number of purchases, while Premium concentrates your currency on fewer attempts at a higher item tier.
2 Recommended Diablo 4 Purveyor Settings
Start with a short target list and keep enough Obols aside for a Premium purchase if you want to compare the two paths. These are spending recommendations, not mandatory game settings.
Suggested Spending Plan
| Setting | Recommended Option |
|---|---|
| Primary entry | Curious Addition for purchase volume |
| Target slots | Two or three slots needing upgrades |
| Premium reserve | Enough Obols for one displayed Premium price |
| Purchase pace | One item at a time |
| Result tracking | Record cost, slot and item results separately |
Buying one item at a time makes it easier to identify a bonus item and associate it with the correct purchase. Check the item and your inventory before spending again; an absent bonus still means the original Obols were spent.
Use this plan as a starting point, then adjust it to your goal. If only an Ancestral upgrade would help your build, reserve more for Premium; the tradeoff is fewer total purchases and no assurance of an Ancestral result.
3 Gear Slot Priorities for Curious Addition
Choose slots according to what your character lacks, then check which ones the selected Purveyor entry actually offers. The following groups are practical priorities, not fixed item outcomes.
| Gear Group | Primary Need | What to Check |
|---|---|---|
| Helm and chest armor | Survival | Useful defensive affixes |
| Pants and boots | Survival and movement needs | Affixes that fit the build |
| Gloves and weapons | Damage | Relevant offensive affixes and item power |
| Jewelry | Build support | Useful affixes and legendary aspects |
The groups work together because a damage upgrade is less helpful if your character cannot stay alive, while extra defense may not solve a damage shortage. Pick the weakest relevant slots first rather than distributing purchases evenly.
Helm and Chest Armor
Use these slots as starting points when incoming damage is your main obstacle. Compare defensive affixes against your equipped pieces, including the value you would lose by replacing them.
An item with higher power is not automatically a better fit. Keep your current piece if the new affixes do not address your build's needs.
Pants and Boots
These slots can also support a more durable setup, depending on their available affixes. Check what your current gear provides before deciding which slot deserves the next purchase.
If neither slot is offered in the chosen entry, keep the Obols for a relevant option. A possible second item does not make an unwanted slot a sound target.
Gloves and Weapons
Prioritize these when your build needs offensive improvements. Compare item power and relevant affixes with your equipped gear, rather than judging a drop by its appearance alone.
Inspect a bonus item just as carefully as the first result. A second drop may help, but it can also be another piece that does not suit your skills or build.
Jewelry
Jewelry can be a useful target when its available affixes or legendary aspects address a specific build need. Check the offered slots and compare each result with the piece you already use.
Keep promising items until you have inspected the whole batch. Selling or salvaging immediately can make it harder to compare similar rolls.
4 How to Spend Obols on Curious Addition
Use a fixed purchase plan so each roll has a purpose and your Premium comparison remains affordable. The steps below work best when you have enough Obols for several purchases.
• Pick two or three gear slots that could improve your current build, and check that Curious Addition offers them.
• Read the entry label and displayed price before buying. Vendor labels may appear in a different order in another PTR build.
• Purchase one item in your highest-priority slot, then inspect the result before making another purchase.
• Check whether a second item arrived and record the outcome with the slot and cost. The bonus is chance-based, so a purchase can produce only one item.
• Stop the Curious Addition batch while you still have enough Obols for your planned Premium purchase. Compare the displayed prices rather than relying on a remembered amount.
After the batch, count usable upgrades as well as total drops. More items give you more things to inspect, but raw volume alone does not establish which path helped your character more.
5 Managing Premium Purveyor Risk
Protect your Obols by treating Premium as a separate purchase decision, not a renamed Curious Addition option. Its higher Ancestral odds come with a threefold price and still permit lower-tier results.
• Check the Premium tooltip and slot price before purchasing, especially if the PTR text has changed.
• Keep your planned Premium amount untouched during the Curious Addition batch. This gives you a fair chance to try both paths.
• Buy the same target slot on both paths when available. Different slots can make the results harder to compare.
• Record the Premium item's rarity and Ancestral status separately from Curious Addition results. A single result is too small a sample to establish the underlying odds.
• Stop the Premium test when you cannot afford its displayed price. Return to Curious Addition only if an offered slot still serves your build.
A conservative approach saves more currency until you know which slot needs an upgrade. A more aggressive approach spends a larger share on Premium when Ancestral gear is the main goal, but leaves fewer opportunities to obtain other items.
6 Curious Addition and Premium Purveyor Tradeoffs
| Choice | Advantage | Cost or Limitation |
|---|---|---|
| Curious Addition | More purchases and a possible bonus item | Bonus is not assured |
| Premium Purveyor | Higher Ancestral odds | Threefold price without a certain Ancestral result |
Curious Addition is the better starting choice for broad upgrade searches, while Premium is more focused on Ancestral chances. Neither choice ensures that the item has the affixes or aspect your build needs.
At a full 25% bonus chance, four eligible Curious purchases would average one extra item over many purchases; an individual group of four can produce none or several. Use that expectation to understand the offer, not to predict your next result.
7 Final Adjustments for Your PTR Spending
Before a longer session, check your available Obols, the offered slots and the current Purveyor descriptions. Note the PTR build and keep your Curious and Premium results apart so a later comparison remains readable.
If purchases produce plenty of items but few useful upgrades, first check whether your target slots match your build's weakest gear. Change one target slot at a time and compare its results before committing more currency.
Curious Addition suits a search for more opportunities, while Premium suits a focused attempt at Ancestral gear when you can afford fewer rolls. For another way to plan your equipment, explore Diablo 4 Items for sale alongside the options available through play.
