Using Jades best builds in Honkai: Star Rail is the best way of unlocking her complete potential as a sub-DPS unit more specifically, one that operates in teams that have follow-up attacks at the forefront. Alongside Firefly, Jade is one of the new characters added with Version 2.3. For reference, this is the same patch that brought forth the final quests in the Penacony storyline. While the release of Firefly in Honkai: Star Rail occurred in Phase 1 banners, Jades debut was held back until the arrival of Phase 2 character banners.
