Not sure if intentional but it seems the compendium of traits includes only those from creatures you’ve extracted from. Since to enchant something you need the material (which includes the trait description) and you lose the material after the ritual it be helpful if that description were added to compendium for reference after!
Just realized that if an artifact is unequipped you can view its trait from the Items menu. It’d be helpful if trait info could be surfaced when viewing creatures artifact as well.
For this in particular, check the creature sheet. Your artifact trait is added to a second “tab”.
ah much thanks
