Find the rest of the volumes. Shinies do show up using the harvesting tool
The (purple shinies) spawn in the boss rooms and you need a fresh zone so it can't be one previously cleared. If you kill the first boss in a zone and the existing group leaves the zone, the shinies will not appear even if you kill the second or later boss with another new group. You will have to wait another fresh instance. You do NOT need to kill the final boss to harvest the shinies.
2 purple shinies spawn in each instance (3 in Wizard's Den!), so it will take at least 3 runs of each instance to get them all (5 shinies per collection or volume), but it will most likely take multiple runs due to duplicates.
You will also find the shinies (pages actually) in Crypt of Dalnir: Wizard's Den (Event Heroic). This is the easiest and fastest of the zones plus 3 shinies show up in the boss room. Just don't "scribe" any of the pages into the collection(s) until you have all of them!
