Could it be possible to complete the game without using the gacha system?
I went through the list of Blades you can recruit without needing to pull on core crystals, and I tallied up their field skill totals. This includes all the main story Blades, Blades that can be recruited outside of the gacha, (Wulfric, Vess, Praxis, Sheba, Kasandra, Herald and Theory), Crosette, Corvin and both MOMO forms. I'm not including Poppibuster due to needing common Blades for its quest, and I'm also not including the Land of Challenge guests, since they require endgame builds to recruit. (Elma especially)
Anyway, the numbers are:
- Fire Mastery: 6
- Water Mastery: 12
- Wind Mastery: 3
- Ice Mastery: 3
- Electric Mastery: 6
- Earth Mastery: 5
- Dark Mastery: 3
- Light Mastery: 11
- Focus: 14
- Lockpicking: 12
- Fortitude: 14
- Ancient Wisdom: 15
- Leaping: 6
- Nopon Wisdom: 9
- Superstrength: 16
- Keen Eye: 6
- Ichthyology: 3
- Forestry: 12
- Agronomy: 9
- Botany: 3
- Mineralogy: 3
- Salvaging Mastery: 3
- Girls' Talk: 14
With these numbers, would it be possible to clear the main story and all the field skill checks it gives?
