Artificer Extra Item Query

Hallo. I was looking into becoming an artificer, but was not sure about the extra item option. Every enchanted object, with the exception of Artefacts, has a shelf life, but since extra items can be without restriction I was not sure as to how long those enchantments would last for. Can anybody help me with this?
Thanks for all the help in advance XD

Taking Extra Item doesn’t give you any free items at character creation the way Artisan does, just the knowledge of how to make a single item.

When you make that item, it lasts a year, unless you spend the ilium to make it an artefact.


Ooh, thanks
