The materials to AW a druid are CC silver/gold rogue, rune fencer, and bishop. Until we get the second half of the Eastern maps with Fudo the silver bishop being one of the completion drop units, we won't be able to AW Pupuru unless they change the materials again. There's another silver bishop, but we won't get her until the Magic City maps. And there are no gold bishops (except for Noel the gold event bishop who was skipped) in the shrine, so no betting on gacha to get one for Pupuru either.
