Must he done unequipped . <| sep |> I am currently attempting to catch an AlolanGrimer with it ' s hidden ability , power of alchemy . My current strategy for finding this Grimer is that whenever a new Grimer is called I make the original Grimer faint . Hypothetically , if the new Grimer has the hidden ability , there should be a popup saying that Grimer now how has whatever ability the fainted Grimer just had . However , I have made at least 70 Grimer ' s faint and this has not occured . So I guess there are several lingering questions coming out of this . Am I just getting extremely unlucky ? Is there a flaw in my methodology ? Do Pokemon in SOS battles not count as allies ? I am getting fairly frustrated . spoiler Question about SOS Chaining and AlolanGrimer
