Yes. Looks like you get it when you banish 100 creatures in the current event. You would still need it. At least I always do. Because, during the event, that last collection group requires the item fixers dropped by the creatures. In the last few events, I haven’t received enough of those drops until around 40-60% Detective level. I think it helps you get a higher badge at the very end that goes on the event photo you receive. Other prizes come with higher badges.
