I don't think you can get the max portal level yet as not everything has been released yet. This will be a massive task to do this and will take a long time. Im only up to level 35 at the moment. Maybe someone could be kind enough to create a save editor?
A save editor would be great. I would be willing to upload a save if someone was interested in giving it a shot.
http://www.xpgamesaves.com/files/file/4576-skylanders-swap-force/ Here is a save that I just uploaded. It has a Portal Level of 16. I listed the details of the inventory with the save, but the stats and the gold are all saved on the character figures themselves. If anyone is willing to take a crack at making a save editor for the portal level, that would be awesome because it takes a lot of grinding to get it maxed out. I believe the max portal level is 81 but dont quote me on it. Thanks
Most are not that hard but there are definately a few that will take some work to get the stars. Also if you want to max it out you will need to buy 100's of skylanders to complete the collection. Maybe we can put together a team to max out a save? Im at level 52 atm.
