The dispenser is right next to the credit shop guy, it's a small redish yellow sign post that can be easily missed. Speak to it and it will give you the option to roll for a random Pokemon 1 out of 5 for I think 20 credits.
I think there might be something wrong with the event. From what I've noticed the key works only if you speak to Rosetta immediately after your talk with Lilith, however if you talk to Garrett first the key doesn't work. This is just what I've noticed, Ive only talked to Rosetta right after Lilith said not not.
If anyone is having trouble with Rosetta, you should consider raising Scizor. Js, it's stupid good. BTW I really like how NOT selfish this game is with the Variety of Pokemon you can get.
I've gotta say you've really outdone yourself yet again. I haven't enjoyed a game that much since ep 14 of reborn.
Also Honedge for ep. 5 Pretty please?
I'm about 3/4 of the way through I feel like. Had to stop playing so I can savor the game a bit. Anyways the only Bug well not even a bug, just a minor error. All the credit shops in the Centers in Cellia all say welcome to the Blackview credit shop. Also you can buy Tyrunt for 13 credits at the dock, while the little guy costs 25 credits everywhere else.
I would suggest making a couple substitutions on your team. Bench Pangoro since there isn't much he can do in this fight. Replace him with either Walrein, (can find speal in Amertrine cave) or with a good rock type or something with a high defensive stat. like maybe Aggron or a Golem perhaps.
You have a couple options. You can get Elekid, or an Aron. Slowpoke is pretty good too, can take a good amount of hits then heal itself with Slack off.
Gastly was axed and replaced with Misdreavus so I don't think so. And as for vullaby I think you can only get it from the Mystery egg unless Ame put it somewhere in the wild with the most recent update.
Bulbasaur, perfect mix of bulk and power.
Chikorita, Extremely underrated.
Torchic, That speed boost tho.
Chimchar, Cute, and really fast.
Snivy, Contrary Leaf storm anyone?
Froakie, because Greninja that's why.
And Popplio. Androgynous and Badass.
Not sure if this is intended or not but Wonky woods has some massive tiling errors. As if the Tileset was changed around or something and the woods weren't re-visited during the editing stages of development. There are light posts and house tiles in places where trees should be. I would post a screenshot but I'm not sure how to go about inserting pictures into forum posts.
