As it stands, there will be two types of nodes Strong Nodes - these are nodes that instantly heal the party, jailbreak fallen comrades and allow you to change your party with your other characters. These will be common in safe areas such as towns. These also serve as "save points." Weak Nodes - these are nodes that heal your party and jailbreak fallen comrades, but you cannot swap out party members. These nodes will be in dungeons, etc. They also allow you to save. just quick clarification: by swapping party members i mean to change your active party of 7 guys with reserve characters not in the group, not the in-combat swapping of the 7 actives... that can be done at anytime, in combat or in the overworld.
