This guide details how to obtain Heartfelt Thoughts in Infinity Nikki, a growth material needed to evolve the Wishful Aurosa miracle outfit. Obtaining Heartfelt Thoughts requires patience, as the acquisition process is time-limited.
Acquiring Heartfelt Thoughts:
Heartfelt Thoughts are exclusively obtained from the Phantom Trial: Wish Master Chigda, accessible through a Warp Spire in the Realm of Breakthrough. Completing this trial, which requires 60 Vital Energy, yields one Heartfelt Thought.
The Realm of Breakthrough and the Wish Master Chigda trial unlock after completing Chapter 7. This is important to note for players progressing through the main story.
Weekly Limit:
A crucial point: the Realm of Breakthrough, and consequently the Wish Master Chigda trial, resets weekly. Players can only claim rewards once per week. This means a maximum of one Heartfelt Thought per week. To fully evolve the Wishful Aurosa outfit (requiring seven Heartfelt Thoughts), players need seven weeks.

Wishful Aurosa Evolutions:
The Wishful Aurosa has three evolutions, each demanding seven Heartfelt Thoughts. Collecting all evolutions requires 21 weeks (approximately 5 months) of consistent participation.
Realm of Breakthrough Reset Timer:

The Realm of Breakthrough resets every Monday at 4:00 AM. A timer is visible in the bottom-left corner of the trial selection screen. While immediate participation isn't mandatory, players should complete the trial before the next Monday to avoid missing a Heartfelt Thought.
