Campaign Artifacts are not available for use in Legions built for League Play. Campaign-specific scenarios will offer players the option to add a campaign artifact to their Score Sheet. They may then use this item in future games even if their Champion is not present. At the end of each week of the campaign, a Hero may also choose to give up 5 XP in exchange for gaining access to a campaign artifact. This XP is then gone and cannot be used in play but of course, the Champion can always earn more.
