Eight story scenes end on a choice of three answers, and each answer raises one of that hero's attributes permanently. No answer is wasted, so pick the bonus the hero needs.

The exact answers, in order

  • Rain, Earth Shrine: "I'll take point. Follow my lead." gives Strength +3, "We're only here to check that everything is in order. Be ready to fall back if you sense danger." gives Stamina +3, and "Cohesion is key. We need to be aware of each other's situations." gives Spirit +3.
  • Fina, Siren's Tower: "Right, we'll need to rely on your strength now more than ever, Fina." gives MP +10, "Yeah, but not everything in fighting is about being on the offense. I'll leave the defense to you, Fina." gives Stamina +3, and "Don't sell yourself short. We're a team, you're already doing an amazing job, Fina." gives Spirit +3.
  • Lid, Shipyard: "No matter what happens, we'll have your back." gives Strength +3, "There might be a reason behind your brother's change." gives Magic +3, and "Doesn't matter how far away you are, siblings are still siblings." gives Stamina +3.
  • Nichol, Olderion the Aquapolis: "Give us some pointers on strategy again. We're counting on you." gives HP +30, "We're a proper team now, so we've got your back!" gives Magic +3, and "You be you, Nichol, and don't hold back with the suggestions." gives Speed +3.
  • Jake, Dungeon in Zoldaad: "Glad to have you. We'll be counting on you." gives HP +30, "Your rifles will definitely come in handy." gives Strength +3, and "Let's fight for this world, together." gives Stamina +3.
  • Lasswell, Rebel Hideout: MP +10, Strength +3 or Speed +3.
  • Sakura, Village of Sunioo: MP +10, Magic +3 or Spirit +3.
  • Dark Fina, Research Center Ruins: MP +10, Magic +3 or Spirit +3.

Rain and Fina are the two you meet in chapter 1, and each hero's own page has their role, weapon and Limit Bursts if you want to know which bonus suits them. The full roster is on the characters list page.

No answer is wasted

Every one of the three options gives something, so there is no wrong pick and no way to lock yourself out of a bonus. The bigger permanent bonuses are elsewhere: each hero's own sub quest ends on HP +100 and MP +30 plus two attributes, which is a much larger raise than the +3 here. Those eight substories are on the side quests page.

Levels, Visions and equipment raise the same attributes by other routes, so a +3 spread across two heroes is less valuable than putting the same points into one hero's Mastery build.
