Can you only play to build a town in Solo-Self-Found mode? Thanks.

I'd like to be able to access the town maker with my witch and marauder also who are already made and played with. If I had to start a new character to access this, I think I could, yet it should go with the characters already made. I could even pay a $1 or $5 to have my already made characters attached to the town maker mode.

Can you go back to Solo-Self-Found mode from multiplayer to access the town maker?

Not exactly sure what you mean. Sound like you are talking about charters in different leagues and the settlers town?

I can't see all the character on your profile, but I think you are wanting your marauder and witch in standard league to be able to access the settlers town?

Only characters in the league can access the league content. That's how leagues are set up. Sometimes at the end of the league, some of the features will enter the core game and be available in standard, but it is not guaranteed everything will come across. Usually what is and isn't is decided shortly before the league ends.

If you are interested in trying it, there is still a long time left on the league as it has been extended through to sometime next year, I think February. They also created an even that has Necropolis/settlers more recently, that contains the settlers town as well.

You don't need to been in SSF mode, but it needs to be under one of the settlers league flags. Necropolis/settler has some limitations on the league settings, it can not be played as ruthless, but other than that, any leagues with the settlers flag will have the settlers town.

You can't go from trade league to SSF. Some leagues are possible to migrate from into another league, but there are rules about which leagues flow into others. You also can't go from standard mode into the league. There is more information about it on this page: https://www.poewiki.net/wiki/League

Again you do not need to be in SSF to play settlers, there are settlers trade/multiplayer leagues modes. You just need to be under settlers league and not the standard mode, as with any league that gets released.

If you manage a own in Settlers SSF, then only characters you made in Settlers SSF will be able to interact with that town. Standard cannot access the town, and it is extremely unlikely to go core.

Evey new char will have acces to upgraded town.

"Sound like you are talking about charters in different leagues and the settlers town?"

Yeah.

"I can't see all the character on your profile, but I think you are wanting your marauder and witch in standard league to be able to access the settlers town?"

Yeah.

I think I could just decide not to do the town builder mode then. Because after SSF and town builder mode and going to trade mode, my characters won't be able to access town builder mode again. You should just make all trade characters be able to access build town mode for like $10 and I could also do that and PoE people would get $10 per player out there to thought tens of thousands of dollars.
