How to Spot a Good Diablo 4 Item Roll

A good Diablo 4 item roll comes down to three things in this order: the item carries the affixes a real build wants, those affixes rolled high in their possible range, and there are few or no dead lines taking up space. Greater affixes and the item type then push a good item into a great one. If you check those points in that order, you can sort a pile of drops in seconds and know which ones are worth keeping, using, or listing.

This guide focuses on reading the item itself. For pricing what you find, see how to price items in Diablo 4 and the value notes on /prices.

Start with the affixes, not the numbers

The most common mistake is getting excited about a big number on a line nobody cares about. A perfect roll on an affix that no popular build uses is still a weak item. Before you look at any value, ask one question: would a build actually want this line?

A quick way to judge this:

• Know the wanted lists. Every popular build has a short list of affixes it looks for on each slot. Learn the lists for the builds you play and the ones that are popular in the current season.
• Count the matches. An item where every affix appears on a build's wanted list is rare and valuable. One with half its lines matching is often just a stepping stone.
• Look for dead lines. An affix that no build in the class wants is a dead line. Each one lowers the item's ceiling, because the buyer will keep searching for a version without it.
• Think about more than one class. Some affixes are wanted by several classes. Items built around those shared lines have a wider pool of buyers.

If an item fails this first check, the rest of the evaluation does not matter much. Salvage it or sell it to a vendor and move on.

Read where each roll sits in its range

Once the affixes pass, look at how well each one rolled. Every affix can roll within a range, and the gap between the low end and the high end can be large. Two items with identical affix lines can be worth very different amounts depending on where those rolls landed.

Before you judge anything, get a sense of the possible range for each affix you care about. Comparing a roll against its range tells you far more than the raw number does.

Some practical habits:

• Weight the important lines. A high roll on the affix a build cares most about matters more than a high roll on a minor line. Do not average them all together.
• Treat low rolls on key lines as a flaw. An item with three great rolls and one weak roll on its most important affix is usually worth less than the numbers suggest.
• Compare against what you are wearing. For your own use, a strong roll only matters if the whole item beats your current one after the change.
• Check item power too. Higher item power generally lifts the base values on the item, so a lower power version of the same item is usually a weaker find.

Greater affixes and how they change the picture

Greater affixes are boosted affix lines and they are a big part of what separates good items from chase items. An item with a greater affix on a line a build wants is often worth more than a similar item with slightly higher normal rolls everywhere else.

A few things to keep in mind:

• A greater affix on a dead line is still a dead line. The boost only matters if the affix is wanted.
• More is better, if they land on the right lines. Items with several greater affixes on wanted lines are rare and draw the most interest from buyers.
• Do not ignore the rest of the item. A greater affix does not save an item whose other lines are useless.

For a full breakdown of how they work and why buyers chase them, read Diablo 4 greater affixes explained.

Slot, item type and rarity

The same affix set can be more or less useful depending on where it sits. Some slots are harder to fill well than others, and builds often have a specific item type in mind for a slot. A great roll on a slot that builds rarely struggle to fill tends to be worth less than an average roll on a slot everyone has trouble with.

Rarity changes the question too:

• Legendaries are judged mostly on affixes, rolls and any greater affixes, since their power can come from other sources.
• Uniques come with fixed effects, so you mainly judge how well the variable parts rolled.
• Mythic Uniques are account-bound. You cannot trade one no matter how well it rolled, so judge it only for your own builds.
• Charms and Seals are tradeable, so a strong one is worth checking against demand before you decide what to do with it.

If you want a refresher on how each tier works, the Diablo 4 item rarity guide covers it.

Judging a roll for yourself versus for trade

These are two different questions and it helps to keep them apart.

For your own build, a good roll is one that improves your character. Even an item with one dead line can be an upgrade if its other rolls are strong and it replaces something weaker. You do not need perfection, you need better than what you have.

For trade, a good roll is one that many players want. That means wanted affixes, high rolls on the important lines, and ideally greater affixes. Buyers compare against the best version they can find, so small flaws cost more on the market than they would in your own gear.

Once you think an item is worth listing, check what drives its value on /prices, then list it on the trade board for in-game gold. Every trader there uses a Battle.net-verified BattleTag and trades happen in-game. Buying or selling items or gold for real money breaks Blizzard's terms of use and can get an account actioned, so keep every deal in gold and items.

A quick routine for sorting drops

When loot is piling up, run through this list on each item:

1. Is it an item type and slot that a build cares about? If not, drop it.
2. Are most affixes on a wanted list? One dead line is a warning. Two usually ends the check for trade.
3. Where do the key rolls sit in their ranges? High on the important lines is what you want.
4. Any greater affixes, and on which lines? On wanted lines, this is where value jumps.
5. Is it tradeable? Mythic Uniques are not. Charms and Seals are.
6. Keep, use, or list? Decide using the table above.

The less junk you have to look at, the faster this goes. A good loot filter hides the item types your build never uses and recolors the ones worth a closer look, so your eye goes straight to the drops that might pass the checklist. Diablo 4's in-game filter supports up to 25 rules, each set to Show, Hide or Recolor with a color you choose. You can grab a shared filter for your class on /loot-filters, where each one is decoded into its rule list. On PC you can paste the import code. On console you cannot paste codes, but the rule list works as a checklist for rebuilding the filter by hand.

Over a few sessions this routine becomes automatic. You will glance at an item, see the affix lines, check the key rolls against their ranges and know within seconds whether it belongs in your stash, on your character, or in the salvage pile.

Frequently asked questions

Is a high roll on a useless affix still worth keeping?

Usually not. A perfect roll on an affix no popular build wants adds little value. The affix has to matter to a build first, and only then does the size of the roll start to count.

How many affixes need to be good for an item to be worth trading?

There is no fixed number, but every affix that matches a build's wanted list adds value and every dead affix takes away from it. Items where nearly every line is wanted, with high rolls, are the ones buyers search for.

Can I trade a well rolled Mythic Unique?

No. Mythic Uniques are account-bound in Diablo 4 and cannot be traded, so however good the roll, it stays with your account. Charms and Seals, on the other hand, can be traded.
