Vernal Growth Cloak

Overview

Vernal Growth Cloak is a Legendary Hunter cloak (the Hunter class item). Each piece's flavor text is one line of a teaching-themed list (humility, critical thinking, curiosity, flexible perspectives) followed by the event-armor Good Moods note. The cloak's line is "Demonstrate flexible perspectives". It is a cosmetic-leaning armor piece with no named perk or god roll in the sources I used.

Acquisition

The Destiny 2 Wiki files the Vernal Growth armor under Season 6 and the 2019 Revelry spring event, obtainable from Bright Engrams. The wiki's Vest entry says the event armor improves the "Good Moods" effect. The same entry lists an intrinsic of improved Recovery (a Resilience and Recovery focus), though that is documented for the Vest only; perks on other pieces may differ.
