WHERE & HOW TO FARM
Where to farm
Battle Flag Supplies menu after collecting Dragon Vein Crystals or Essences in battlefields.
Dragon Vein Crystals increase the number of Dragon’s Cure Pot uses, while Dragon Vein Essences improve the amount restored. Both are fixed battlefield collectibles. Collect them as you explore, then apply them from the Cure Pot option at a Battle Flag so the permanent benefit is active.
Leaving an item unused: visit a Battle Flag and apply it through the Cure Pot menu.
When to stop or switch
Stop when all available upgrades you need are applied; if a specific item is missing, switch to its named mission rather than re-searching cleared areas.
