FFVI: Divergent Paths

Other airship NPC ideas:

• Stats Changer - either allowing you to customize by choosing 1 boost per character (ie: choose +5 strength or +5 magic power), or allowing you to implement tradeoffs (such as reduce HP to raise MP).
  
• De-leveler - in case you want to re-levelup at the end of the game now that you have better espers with better levelup abilities.
  
• Background Trainer - choose 4 characters to do "training". These characters are awarded some amount of EXP but cannot be added to your party until X battles are won.
  
• Costume / Palette changer - would require a list of alternate sprites and/or palettes available per character that could use this feature.
  
• Hints - gives you clues that guide you to events and secrets that have changed in this hack. Needs to know which secrets and events you haven't encountered yet, then chooses from a table of prewritten hints based on that.
  
• Loremaster - gives you clues about where to go to get new Rages for Gau or Lores for Strago. Would need to know what you don't have yet and chooses from a table of prewritten hints based on that.
  
• Random Gifts - Just a character who does nothing most of the time, but sometimes is like "hey I found something you might like" and gives it to the party. Would need to decide whether to give gifts or not based on something that can't easily be cheesed by the player - maybe X battles need to be won and X time needs to advance on the game clock.
