This guide explains how to obtain Heartfelt Thoughts in Infinity Nikki, a growth material needed to evolve the Wishful Aurosa miracle outfit. While acquiring them isn't complex, it's a time-consuming process.
Obtaining Heartfelt Thoughts
Heartfelt Thoughts are exclusively obtained from the Phantom Trial: Wish Master Chigda, accessible via Warp Spires within the Realm of Breakthrough. Each successful completion, requiring 60 Vital Energy, yields one Heartfelt Thought.
The Realm of Breakthrough and the Wish Master Chigda trial unlock after completing Chapter 7. This is relevant because the material isn't needed before this point in the main story.
Realm of Breakthrough Limitations
A crucial point: the Realm of Breakthrough allows reward collection only once per week. This means a maximum of one Heartfelt Thought per week. Fully evolving the Wishful Aurosa, requiring seven Heartfelt Thoughts per evolution (three evolutions total), necessitates a consistent 21-week commitment.

Wishful Aurosa Evolutions
The Wishful Aurosa has three evolutionary stages, each demanding seven Heartfelt Thoughts. Collecting enough for all three stages requires 21 weeks, or approximately five months of consistent participation.
Realm of Breakthrough Reset

The Realm of Breakthrough resets every Monday at 4:00 AM. A timer displays on the trial selection screen. While immediate participation isn't mandatory, players should complete the Wish Master Chigda trial at least once before the next Monday to avoid missing out on a Heartfelt Thought.
