So far, I have established:
- Sometime around Chapter 4-5, Chimecho gives you the Yuujou (Friendship) Bell. This allows you to recruit anything. The more evolved it is, the harder it is to recruit. Friend Areas are not needed, nor are they included.
- You can recruit as many Pokemon as you want in one dungeon. If you have less than 4 with you, they will team up with you. If you have 4 Pokemon on your team and another wants to join, it will go straight to the Guild and will be with Chimecho.
- Pokemon that are recruited will stay recruited even if you or your partner lose all of your HP.
EX: I recruit Riolu and Graveler. Another Riolu in the dungeon reduces my HP to zero. When I appear back at my base, I will still have Riolu and Graveler on my team. (Yes this really happened)
- If you recruit a Pokemon and you want it to go back to the guild, you can send it back manually so you don't lose it.
I will add more features as I find them.
