I want to use a signature so people can say "oh yeah that guy did it" and the only possible way for me to do it is by custom portraits which seems okay but i'm double checking

Does the Imports have any limitations like no bringing key items from the first run into the other?

Can we have a new game+. I wanna speedrun Underrail but i dont want to use a new character each run. I have a character i wanna use for a New Game+ run. Also the current version of Underrail's speedrunning rules doesnt properly represent Underrail's current version
