Return after story for missed upgrades

Battlefield map, then the relevant mission and its known pickup landmark.

Before you go

Check your Dragon’s Cure Pot upgrade status and identify whether you are missing a Crystal, an Essence, or both.
Use the battlefield map to select the mission associated with the missing item.
Enter the mission and progress toward its recorded landmark, such as the county office chest in Two Chivalrous Heroes.
Explore the named branch or room and collect the fixed pickup if it remains unclaimed.
Continue to a Battle Flag and open Supplies, then Dragon’s Cure Pot.
Apply the item and confirm the Cure Pot’s capacity or recovery has changed.
Return to the map and choose another mission only if another upgrade is still missing.

Collectibles remain obtainable after story completion, so you can leave a difficult optional branch and return later.
Use the mission name and landmark to keep a replay focused instead of clearing unrelated content.

Limited to missed pickups. Each Crystal or Essence is collected once per playthrough; replay does not make another copy appear.

Replaying a mission without identifying the missing item: check the upgrade state first.
Treating a cleared pickup as farmable: choose a different missing collectible instead.
Forgetting to apply the item: finish at a Battle Flag’s Cure Pot menu.

Stop when all the missed upgrades you want are collected and applied; return to normal progression or another remaining target.
