Keep in mind there are three locations for gear: Character, Mercenary, and Stash. Extra storage space can be gleaned from Mercenaries, but managing these items can be cumbersome. Using extra character slots as item storage also helps.
There are many resources mentioned by others; Icy Veins’ D3 “Salvage Guide” page is great, which gives a huge list of items and build guides they appear. This will at least get you started in recognizing useful items/stats until you become more familiar.
Stash Tab Organization
A way to effectively increase storage space is storage organization. This will reduce cognitive drain of comparing/filter duplicate items and also help with combat downtime.
One strategy I have been using is grouping Stash Tabs by primary stat. I’ve got 13 stash tabs and adopted a nifty way of keeping all sets for every class and their misc pieces intuitively organized.
My very first tab is Gems, Legendary Gems, Infernal Machines, Staff of Herding, and some misc items. All the other tabs are class/primary stat oriented, here is the tab template I use:
Tab |
Desc |
2 |
Class A Set Pieces |
3 |
Class A Misc + Class Agnostic + Class B Misc |
4 |
Class B Set Pieces |
This repeats for Tabs 5-12. The layout for a Class Set Pieces tab is fairly simple; each class set takes a two cell high row and the last remaining two cell row is alternate stat pieces and weapon slot sets. The clever part is tab 3 between these two class set tabs, here is a row breakdown:
Row |
Desc |
1/2 |
Bracers/Belts/Speed Variant/Etc items (Class A) |
3/4 |
Bracers/Belts/Speed Variant/Etc items (Class A) |
5/6 |
Rings/Amulets/Belts/Etc |
7/8 |
Bracers/Belts/Speed Variant/Etc items (Class B) |
9/10 |
Bracers/Belts/Speed Variant/Etc items (Class B) |
For instance, Barbarian Tab | Strength Tab | Crusader Tab
:
Many non-set (and many time class specific) pieces like bracers/belts/weapons/shields can be placed in rows 1-4 (Barbarian items) or 7-10 (Crusader items). Row 5/6 can hold the common inter-class items, like: Focus/Restraint
, Compass Rose/Travelers Pledge
, The Witching Hour
, Litany/Wailing
, Aquila Cuirass
, etc.
This can be repeated for Demon Hunter/Monk, Wizard/Witch Doctor, and Necromancer/Other.
While this doesn’t help you identify which items to keep, it will at least reduce the amount of processing the ol’ noggin has to do.
Anti-Hoarding
Since increasing storage limits caps out, ultimately developing an anti-hoarding strategy is required for proper storage management.
In general, setup a time threshold for getting rid of any non ancient items. If you haven’t used an item in over a (week/weeks/month, relative to playtime of course) shard the badboy. Multiplayer farming is pretty quick these days, which is good enough to get some base level build items.
