About B Spheres

They generally lean toward improving defense capabilities.
Keywords for the abbreviations below are referenced at the bottom
What is best?
- Every character is different, but there are some general rules
- ATK spheres are generally the best options as long as you can trigger the effect, with other stat boosts being useless
- BRV gain spheres are decent on Encouragement Keystone holders like Warrior of Light, Galuf, Snow, Beatrix, Gladio, and others - but Gladio's sphere is still better for them
- Lowering party BRV damage & HP damage is better than nothing

All B spheres

The thing to look for with these spheres is whether your character can inflict the Lock debuff, or can cover your allies from attacks. Take HP Damage is a frequent trigger, and defensive characters that don't Lock/Cover will be forced to choose between Celes, Gabranth, Kimahri, or Warrior of Light spheres.
