Hi there, so Aileen can achieve a perfect 19 chain w/o using a macro, but where she is placed on your team matters a lot. Without this placement, it's actually extremely hard to get the 19 chain consistently, unless you just have amazingly fast fingers lol.

So basically you want to put your Main Aileen in the front, in slot 2(red box in picture below, and your second Aileen in slot 4(yellow box in picture below). This, for me, has been the most successful set up to 19 chain Aileen on your phone w.o macros.

Now, if you don't have a second Aileen(I was lucky, and pulled my second from 6 tickets I had saved up), this set up will work exactly the same instead of the obvious switch from your 2nd Aileen being in slot 2 at the top, it will be your friend Aileen in slot 6(blue box in picture above).

Anyway, this is a simple tip, but I hope this help some of you Aileen enthusiast like myself!

P.S. Feel free to add me if you're looking for a constant Aileen friend unit!
