OK, got a couple of newbie questions for playing Pathfinder Adventures on Ipad. First, I bought some cards through the chests and I'm confused on what the different types of decks mean. Know for sure I can access the B deck cards through the story, but what about all those other decks like '1' '2' and '3'? Are those accessed through story? Are they accessed through Quests? Which bring up another question. I cannot seem to get the guys in my story mode to be used in Quest Mode. I mean i can use level 1 new versions of them, but not the ones currently leveled up with items. If I complete the Story Modes, will I then be able to use them in Quest mode? Fizzleup

If I just close the story (click the 'x') and start it again, do my characters keep their experience and items? Also does it still show the scenes completed or do I have to do them over again?

Let me ask this, what if I go to Story, click the 'x' on the top right of the Rise of the Runelord story, and then choose a new party? Will my characters still have their experience and items from the previous story attempt? Also will it still show that I completed those scenarios I already finished in the first try with the story?

So I have the pathfinder adventures ios on ipad air. I've been playing the Rise of the Runelords story with a full party of six. I decided I wanted to change one of my characters and bought a new one. Only problem is I can't seem to switch out any of my characters. In party screen all the current members in my party have a lock symbol on their face and I can't seem to remove them from the bottom row which shows the party members. Is this a bug or intentional? Do I just have to start a new story if I want to change my party members around? Fizzleup
