Quick answer
Yes. Natsume connects solved Power Statue puzzles with Power Wisp Fruit, which is used to increase maximum stamina.
Evidence checked
- Power Statues are found across Teradea.
- Their puzzles award Power Wisp Fruit.
- The fruit is connected to maximum-stamina growth.
How to use this answer
A stamina guide should state the loop now and reserve optimization tables for verified values.
The answer is scoped to Harvest Moon: Echoes of Teradea and the public evidence available on 2026-07-29. It does not import schedules, values, controls, item data, or progression rules from an earlier Harvest Moon game.
What remains outside the evidence
The upgrade mechanism is confirmed, but statue count, fruit requirements, and stamina increments are not.
If Natsume, a verified platform storefront, or reproducible launch-day testing supplies the missing field, this page should be updated with the exact source and review date rather than silently replacing the earlier status.
