No, you can get the location of the main missions only through interacting with Momonga's token. Orange names are side events only. Charges can actually be recharged if you discover the door to another world (and if you discover it when you do not need it, simply leave it alone and save it up for when you do.)After finishing this I can honestly say this game was great and I could tell how much you cared about doing this series justice, even in this context.
The only personal gripes as a completionist were the limited number of charges on the ring on certain days and the fact that you cant get all the characters on a single run.
I hadn't played since R22, so some things might have changed, but does the orange names on the map also include main mission scenes? Because if so thats a little unhelpful in locating side content, especially since you can just click Ainz to know where the next main mission is, and if not then using a save from an old version has bugged it, since no matter what, the main sorcerers kingdom is always orange even with no available side content.
Also I really need a full walkthrough since I've beaten the game once and I'm still missing a bunch of mirror scenes and still somehow only have about 40% of the gallery and scenes.
At this point, I am fairly sure if the Sorcerer Kingdom is orange, you are missing an event... If you open up the sorcerer kingdom, where does the pin point? Should be either E-Rantel or Carne Village. Gazef (if he exists) needs Brain Event in the lizardmen lake as well.
If you have completed the game and you are missing more than half of the gallery, then yes, you have skipped quite many side events.
