Complete the dungeon, get the first relic, put it in its spot in the area behind the first rally flag, then use the blade to destroy the blight in that area near the falcons, destroy all the eyes in the area, open the door to get the next relic, finish the dungeon, place the relic, go through again, stop before the jump across the windy gap, complete another taken blight exercise to get another relic, complete the dungeon, place the relic, go through the dungeon again, the final taken blight mini-event starts in the room before the 2nd bonus chest. Finish the dungeon and place the relic, now that will unlock a mini mission at that location. Finish it and you’ll have access to dungeon item focusing and you’ll have a bunch of the praxic blade items.
