So the way estus works in this game is actually a returning mechanic from From Software's King's Field series.

In King's Field you collect crystal shards and use them to make Crystal Flasks that allow you to carry more healing potions.

In Dark Souls II now there will be estus shards or whatever that basically is the same thing for more flasks.

Just an interesting observation.
