I'm chaining Grimer to try to get one with power of alchemy (it's hidden ability). I was wondering if the ability would actually activate if it was on a wild Pokemon so that I can see when I encounter one with that ability.
Yes, after I think 30 SOS you'll have to kill the 1st Grimer, if it doesnt get his friends talent, kill it untill one of them happen to get his friend's talent, that"s how I got my Grimer, but I don't event know how i'll play it
