Quick answer: Collect Memory Flowers. Finishing a flower set raises max HP, and each card shows its bonus. Accessories such as Jewel’s Knot add more on top.
Memory Flowers raise max HP
Memory Flowers are glowing blue flowers in the world. Each one belongs to a set, and each set’s card shows the line “Collect all Memory Remnants to increase HP” along with its own flower count and HP bonus.


Set sizes and bonuses differ from card to card. The Inanis card shows +5%. The Villagers of Lu card shows (1/4) with +7%. The Firefly and Leng Tu cards show (1/6) with +10%. Bitter Kin’s two petals show +5%. Yan’er’s six flowers are one full set.

The Jewel’s Knot card reads “Increases HP by 15%.” You only get that bonus while the accessory is equipped.
What does not raise max HP
Two systems can look like HP upgrades, but they leave the cap alone:
- Longevity Tonic refills your health bar without making it longer. Its card reads “Restores all HP.”
- Medicine upgrades give you more uses and stronger healing, but your max HP stays the same.
Healing and max HP are tracked separately. To make the health bar itself bigger, complete Memory Flower sets and equip Jewel’s Knot.
