Phase 1 Banner & Event Overview

Featured Character Banners: Dialyn’s Debut & Accompanying Units

Phase	Dates (UTC-5)	Primary 5★	Additional Characters
1	2025-11-25 to 2025-12-17	Dialyn (new), Hugo (rerun)	Billy, Corin
2	Anticipated late December	Ellen (rerun), Banyue (debut)	[Phase 2 units to be announced]

**Dialyn** will be introduced with the 2.4 update, serving as the main draw for Phase 1 banners.
**Hugo** will make a reappearance, offering a valuable addition for players focusing on Ice-element teams.
**Billy** (Physical-Attack) and **Corin** (Physical-Attack) complete the roster of boosted characters.

Phase 2 Information: The second phase is expected to introduce **Banyue**, a member of the Krampus Compliance Authority, alongside a rerun for **Ellen**. Specific details regarding the full character roster and exact rate-ups for Phase 2 are yet to be officially disclosed.

Strategic Pulls: Is Dialyn Worth Your Investment?

For players operating on a free-to-play model or a limited budget, several factors should influence decisions regarding Dialyn’s banner:

**Simultaneous Rerun:** This banner runs concurrently with a potent rerun for Hugo. Players with robust Ice-element teams might need to deliberate Dialyn’s novel abilities and fresh presence against the potential of future character reruns.
**Krampus Compliance Introduction:** Acquiring Dialyn early grants access to emerging gameplay mechanics and establishes synergy with future characters, such as Banyue in Phase 2.
**Gacha System Fundamentals:** The familiar ZZZ gacha rules remain in effect (a 90-pull soft pity/guarantee, and a 50/50 chance for the featured 5-star character). Strategize your Polychrome and Film expenditures carefully. For optimal currency management, consult **GenshinBuilds’** guides on saving resources.
**Roster Optimization:** If your current character lineup is largely complete apart from Dialyn, securing her now could benefit future team compositions. However, if your pull currency is scarce, it might be prudent to save for upcoming, unannounced banners.

Character Combinations & Team Dynamics

**Dialyn** is poised to elevate teams that capitalize on the newly introduced Krampus Compliance Authority synergies. Prime candidates for her most effective squads include Hugo (an Ice-focused attacker) or versatile Physical damage dealers like Billy and Corin.
**Budget-Friendly Options:** Billy and Corin, both featured with boosted drop rates, present excellent and accessible choices to complement Dialyn for efficient team construction.
**Looking Ahead to Phase 2:** The arrival of Banyue is expected to further strengthen the Krampus Authority’s potential. It may be wise to delay significant investment in certain builds until her full abilities are officially revealed.
