Hyacine is one of the two upcoming units for Honkai: Star Rail Version 3.3. She is a 5-star Wind unit following the Path of Remembrance. Hyacine is a new 5-star healer that works alongside her Memosprite, Ica, to heal your team and increase their MAX HP by a staggering amount. From her kit, we can speculate that Hyacine will be a great support for units that scale from MAX HP, such as Mydei and, more recently, Castorice. In this guide, we’ll show you full breakdowns of Hyacine’s skills and constellations to give you a deeper understanding of the unit and help you decide whether to save for her or not.
