Any ARPG without some sort of crafting system in it is not an ARPG. The majority of ARPGs you come across, like Diablo III and Path of Exile, require you to go to your main house, base, or a hideaway in order to craft things.
However, in Last Epoch, you don't have to worry about that anymore. Here, pretty much everything, with the exception of legendary equipment, can be customized.
You don't get to change the appearance of the item or the color to do so; with all of the crafting materials you find on the ground, you can increase the stats of any piece of equipment. Just make sure that you are customizing your equipment based off how your character is progressing.
