For vanilla torchlight 2, it is possible, you can find list of unique and set items if you search around.

For modded torchlight 2 it is harder. You would need to find a list of unique/set items for Synergies, and also a list of unique/set items for essential, which is itself a mod compilation.

For Synergies I know there used to be one in the official synergies forum, but that forum is not available anymore, it closed a long time ago. Maybe it has been replicated somewhere.

That said, you could do a Holy Grail of vanilla items in a modded game.

Ok, ty bro. I go search for list vanilla and try find list of mods too!
