it makes sense. but then again, you can also make money selling non legend items you pick up. you might also make more money picking up all items and selling what you don’t need if you plan on getting Dealer when you ascend.
I always keep the highest quality item of everything I found, and keep
all copies of different items with different skills (since my
understanding is that you cannot change a skill of an item). Is this
correct?
on weapons, you can change most affixes and the weapons’ special skills but not the primary ones
on armor and jewelry, you can change most affixes and the talents too.
to make these changes you will need crystals. you can refer to:
Griffin’s Smithery: Crystals
some affixes, on the other hand, cannot be changed. so the legends with these affixes are the ones you should keep. check out:
Skaul’s Hierarchy of Tips and Tricks SHTT 2.1.0.3
on that thread theres a list of sought after items. there’s also a list of affixes including which ones you can/can’t roll with crystals.
again you should just keep the ones that are really hard to get. i kept an organized storage with complete item sets when i first started out. i then realized that it’s impossible to keep all of them so nowadays i just keep the rare ones.
