Yea so I had an entire post ready and copied it too and now it magically disappeared into cyber space fun times.
I have an idea for BnW 2.0 that is greatly inspired by Breath of Fire 2 involving NPCs offering the player a ONE time PERMANENT enhancement or spell. I find this idea intriguing because it encourages more diversification of character builds and forces the player to make a strategic decision on who to give the buff to. Here are some examples of possible NPC buffs.
Lola, the lonely woman Cyan was sending flowers and letters to. She could thank Cyan for his attention by offering ONE character a Hp+200/Stam+6 boost. Almost everyone would benefit from the boost, it might especially be helpful for Strago to fuel his White Wind or to make Gau/Shadow tankier since they lack alternative methods of boosting HP.
Gungho, Strago's friend who was injured by Hidon. He could offer ONE character a Mp+100/Mag+6 boost which would especially benefit magic users who lack an MP boosting esper such as Locke or Mog or even a Vigor based Terra/Celes for MP crits and Holy/Flare procs. The player can decide where the boost would fit their play style best.
Gau's Father, As a thank you for letting him know his son is alive after the cute sequence could offer ONE character a Vigor+5/Speed+5 boost which would could be used to further buff a physical dps character or give more dps to a tank such as a Terrato Sabin or Unicorn Terra.
Rachel, Before departing from her brief resurrection can offer ONE character the Life 2 spell which allows the player to have 3 characters (Terra and Locke being the other 2) who can revive someone to full HP and would benefit pretty much anyone since it is not tied to any stat. A tanky Sabin or Cyan build may benefit most from access to this spell since they are likely to not be KOed and have opportunity to utilize it.
The Queen Statue, Which in this mod is basically just "there" since Raiden is no longer an Esper could offer ONE character a choice of ONE of the level 2 elemental spells: Ice 2, Fire 2 OR Bolt 2. These spells could be used to round out someone's elemental coverage, such as giving Locke Ice 2, or providing a character with few elemental attack options like Setzer or Edgar a new magic attack option.
Other possible NPCs who could offer bonus are Duncan and Owzer, but I think I got the idea across. I find this very intriguing because there are a lot of different rationales for giving these boosts to different characters so it can cater to any playstyle.
