Any decent loot filter should already show only those uniques that have valuable uniques in their drop pool.

Generally speaking your best bet is to check the value of it unidentified first. It’s mainly items like Morior (body armour from arbiter), jewels like Against the Darkness, Voices, Prism of Belief that are worth more unidentified.

It’s difficult to accurately filter it because even a cheap unique like a Kaoms Heart can sell for well over 50 div if you corrupt it and the life over rolls, whereas one without the corrupt will sell for a few chaos at most.

Some uniques like Rathpiths Globe, Astramentis, and belts like Headhunter and Mageblood (HH is dirt cheap now tho) are always good bets to ID. You can often make good money by just quality, socket, and corrupt on some uniques. Just depends on what’s meta at any given time, but an Alpha’s Howl for example can sell for shitloads if you get lucky and over corrupt the spirit and then double corrupt for a spirit enchant.

Chance for good uniques: unique gems, utility belts, heavy belt, sacred focus? .

All unique rings should be picked up imo, cause you can use a lot of them for loreweave. Unique charms, a lot are good.

Thats about it, but get a loot filter, that will decide for u

If you arent using a loot filter it just takes time to learn what has value. Some uniques work in niche settings, others are part of a well known build which boost their value and some others can be usable but arent worth anything currently.

If you are not playing SSF then it ismt usually that great collecting them all. Heavy and utility belt for headhunter and mageblood are arguably the best belts in the game. Some builds like a specific belt from the breach mechanic but that isnt the majority.

Just keep playing, learn to recognize what the uniques are and if theyre good or not and if you start making a lot of divs theyre usually not worth picking up. Exception is to collect uniques if you have the tab just to fill your collection, collect rings for lore weave or a specific unique you like to put resources in to craft and sell for a specific used build.

I’m not sure such a list exists somewhere, things are bound to change anyways as the game releases. Would be useful though.

As a general rule though, your loot filter will likely help. Whenever you see different colors, it likely means it’s worth something (at least for SSF) and it’s time to check the price.

For unidentified stuff, you mostly have to determine whether it’s an item with random modifiers. As of now, these items are often mostly vaal items (found in the temple of trial of chaos), and various jewels dropped by pinnacle and trial bosses. If you want to be extra careful, it’s nice to have both the wiki and trade tab at hand.

Beside these, there are a few items such as Widowhail or Constricting Command which value can vary a lot depending on the value rolls, but they typically don’t tend to become too expensive even on the high end. You’ll learn them eventually, if you bother with them at all.

One mans trash is another mans treasure.
