MAJOR UPDATE: It has apparently been confirmed by the Pokémon GO Company in Japan that players can go through the search for Mew only once! Does that mean that Mew will be a guaranteed catch similarly to Shiny Lugia? Time will tell.
Btw, stamps are unrelated to mythical tasks. So u can complete mew tasks at your own pace.
Stamp is rewarded from doing 1 field research task daily.
8/8:
Mythical discovery:
3/8 Battle 2 raids
6/8 Battle 10 raids
You do not have to spend 12 raid passes in that case! Failing a raid and re-entering the same raid will count as 2 times (repeat again for the entire duration of raid)
"Quitting" in the middle of a raid battle and then enter again count as +1?
