Diablo 4's Curious Addition suits players who need more item rolls, while Premium Purveyor costs three times as many Obols for better Ancestral odds. During the Oct 27-Nov 3 PTR window, check the entry label and price before spending, then use Diablo 4 Items to compare useful slot targets for your build.

Choose Curious Addition slots by gear need

Curious Addition slot selection starts with the item slot you actually need, not the Two for One text. Open the Purveyor interface, identify Curious Addition, and read the offered slots and Obols price shown by the PTR build. Helmets, chest armor, pants, and boots commonly support defensive affixes, while gloves, weapons, and jewelry commonly support offensive affixes. These are useful priorities, not guarantees of a better drop. Pick two or three slots tied to current gear needs, including legendary aspect gaps, item power concerns, or Ancestral goals. If your target slot isn't listed, save the currency for a later offer.

1) Open the Purveyor, verify the Curious Addition label, and read the listed slot and Obols price before confirming any purchase.

2) Choose a listed slot that supports your current gear goal, then buy one item and inspect the result immediately.

3) Record the slot, price, and any second item before repeating, keeping enough Obols for a planned Premium purchase.

Match Premium Purveyor to item quality goals

Premium Purveyor changes the slot decision because each purchase uses three times the Curious Addition Obols price and offers higher Ancestral odds. It doesn't promise an Ancestral result, so the extra spend only makes sense when item tier matters more than total rolls. Curious Addition spreads the same budget across more attempts and can return a second item through Two for One up to 25%, capped at 25% and not guaranteed. Compare the tooltip odds and your reserve before buying. A three-purchase Curious batch and one Premium purchase give a direct comparison; judge results by usable items and target slots.

● Choose helmets, chest armor, pants, or boots when defensive affixes are the immediate gap in your equipment and survival matters for your current content.

● Choose gloves, weapons, or jewelry when offensive affixes are the priority and several lower-cost rolls suit your available budget and target list.

● Keep a Premium reserve when higher Ancestral odds matter, since one purchase can equal three Curious Addition purchases at the displayed Obols price.

Full disclosure: A second item is never assured, and an unsuccessful bonus still spends the displayed Obols price.

Measure both entries with a fixed PTR budget

PTR testing needs a fixed budget because mixing the two entries can make slot value and item volume hard to judge. Note your starting Obols, run a defined Curious Addition batch, count the second items, and record the remaining balance before trying Premium Purveyor. Check rarity and Ancestral status on the Premium result, but remember that higher odds don't remove lower-tier outcomes. Stop the Premium comparison if your balance cannot cover its three-times price. Also check the build number and reread vendor text after a hotfix changes the displayed entry, since label order can shift between builds.

● Inspect a bonus item before selling or salvaging, so its slot, rarity, and quality remain part of your comparison.

● Count usable items, not raw drops, because an unwanted slot can waste the value of an extra roll.

● Keep Curious Addition and Premium Purveyor totals separate, then repeat only with a fresh Obols balance and the same targets.

Run a fixed slot test

Start with two or three listed slots, confirm the current prices and tooltip odds, and reserve enough Obols for the comparison you planned. After the batch, browse cheap Diablo 4 Items for additional gear choices, then spend only where the available slot and item tier match your build's needs.
