repetable/new challenges when completing one tome
as the title says, i think that i would be a good idea to unlock some kind of repetable challenge/s, that becomes available after you have completed an entire tome
lets say that you manage to complete each challenge in levels 1 to 4 in the Tome V for example, instead of simply having the tome completed, maybe weekly or monthly one or more challenges related to that tome would become availabe again, and those would again give bloodpoints.
or better, instead of challenges from that tome, one especial challenge or challenges could be unlocked that are only available for people that completed the tome and are related to that tome in particular. using the example given above, since tome V is nea, blight and hillbilly, maybe challenges involving their perks or themselves could be featured. those challenges would unlocked again every ranked season and give a lot of bp but are also either very hard "do in a single trial" type challenges or very long normal ones.
having that would help people that already have a lot of the tomes completed a way to still do challenges, and would also make it so that the rest of the people have an incentive to complete the whole tomes instead of simply going to the epilogue of each one
