It would make sense to me that properly dodging an attack, would likely be dexterity related, and thus every successful dodge could help to train dexterity.

This kind of training could have a similar limit to Strength where it cannot be increased past 20 Dexterity by doing this.

But this would allow players who have high DV, and have abused their Dexterity a bit too much from being Overburdened, to regain some of their Dexterity naturally.
