The introduction of Remey in to the the mix of dragon breath training radically sped things up. Su had not realized that Remey and also somehow used this new alchemy flame she could control to make a better health potion that would work perfectly with her body.
The health potion felt the same as any health potion that Su had drank before, but the moment where things changed was when it focused on the places in her body that were damaged due to using dragon breath. Instead of just healing, it was also helping to strengthen.
The body of anyone would naturally make scar tissue, or calluses, or anything to adapt in some way to certain situations if possible. That was just the flexibility and resilience of the body. However, for Su, it was acclimating better to the dragon breath attacks she was training.
