HSR 4.7 Aha Banner & Affinitive Eidolons Explained

HoYoVerse's 4.7 Special Program just closed the loop on the Planarcadia arc's loudest question: Aeon ★ Aha is playable, and she lands on 2026-11-11 as a 5-star Quantum unit on the Elation path. That is not a drill, and it is not a skin — it is the Aeon of Elation stepping onto the roster while the story pivots toward hunting the Voracity leviathan.

For anyone tracking the patch cadence, this is the kind of swing that reshapes pull planning for the rest of the year. If you need the broader roadmap, the latest Honkai: Star Rail updates hub keeps the 4.6-to-4.8 thread straight.

At a Glance

• New 5-star: Aeon ★ Aha — Quantum, Path of Elation
• Release date: 2026-11-11 (server reset time not stated in official materials)
• Phase 1 banners: Aha, Silver Wolf LV 999, Sparxie Sparkle, Yao Guang rerun
• Phase 2 banners: Acheron, Dan Heng: Imbibitor Lunae, Jing Yuan reruns
• Affinitive Eidolon buffs: Acheron, DHIL, Jing Yuan
• Free pick: one 5-star plus one Affinitive Eidolon via Grab Your Opening Gift
• Redemption codes: NEVERGONNAGIVE, NEVEZRGONNAMAKE, AHABLESSYOU (300 Stellar Jades total)

Banner Schedule and Phase Breakdown

The structure here is unusually front-loaded. Phase 1 stacks Aha with Silver Wolf LV 999 and Sparxie Sparkle alts plus a Yao Guang rerun, which means the opening banner window is a Quantum-and-Elation traffic jam. Phase 2 pivots to the three Affinitive Eidolon recipients — Acheron, Dan Heng: Imbibitor Lunae, and Jing Yuan — so anyone chasing the new Eidolon screens has a clean second window.

Aha's banner goes live the second the update starts, per the Special Program. Exact phase transition date is not stated in official materials; plan around the standard 21-day split until HoYoVerse confirms.

Should You Pull?

Aeon ★ Aha

A 5-star Quantum Elation unit is a genuine roster gap-filler. Quantum has been thin at the top end, and Elation as a path has leaned on follow-up-adjacent playmaking. The catch: we do not have her kit numbers, multipliers, or trace layout. Not stated in official materials.

F2P: the free 5-star selector changes the math. If Aha is selectable, take her and save Jades. If she is excluded from the selector, weigh her against your Quantum coverage before committing.

Low-spend: Phase 1 is the value window if you want Aha plus a shot at Silver Wolf LV 999 or Sparxie Sparkle. Do not split pity across three banners without a hard stop.

Optimal: if you already own Acheron or DHIL, Phase 2 reruns plus the Affinitive Eidolon upgrades may outvalue a fresh Aha pull. Decide based on whether your endgame clears are DPS-gated or coverage-gated.

Rerun Value

Yao Guang in Phase 1 is the sleeper. If you skipped her debut, this is the cleanest window before 4.8's Ellen Joe Ice Destruction debut reshapes Ice team planning.

Affinitive Eidolon Upgrades: Theorycrafting Corner

This is the section that matters for Memory of Chaos and Pure Fiction. The Affinitive Eidolon system adds a new in-battle ability and a new Eidolon screen illustration for three older carries.

Acheron — A Glance through Rime to Bone

Triggers follow-up attacks on enemies with Crimson Knot that are hit. This is a direct DPS extension on her existing debuff engine. In practice, it rewards teams that apply Crimson Knot early and then hammer the target with multi-hit actions. Pair with Pela or Silver Wolf for debuff uptime and watch the follow-up cadence stack.

Dan Heng: Imbibitor Lunae — Moonset Stills the Deep

Raises his Squama Sacrosancta limit and lets him perform follow-up attacks after allies spend Skill Points. This is the most rotation-sensitive of the three. DHIL teams already burn SP aggressively; the follow-up triggers turn that spend into extra damage. Sparkle and Tingyun become even more attractive supports here.

Jing Yuan — One Quiet Cup of Thunder

Lightning Lord gets more max hits and a damage boost when enhanced. This is the cleanest upgrade of the batch. Jing Yuan's ceiling has always been Lightning Lord hit count; raising the cap directly lifts his Pure Fiction and MoC performance. Sunday and Robin remain his best enablers.

Events, Rewards, and Redemption Codes

Three codes are live for 2026-10-30:

Code	Reward
NEVERGONNAGIVE	Stellar Jades (portion of 300 total)
NEVEZRGONNAMAKE	Stellar Jades (portion of 300 total)
AHABLESSYOU	Stellar Jades (portion of 300 total)

All three together award 300 Stellar Jades. Redeem in-game via the code menu before they expire; expiry window not stated in official materials.

Grab Your Opening Gift lets you choose one of the five stars for free and one of the Affinitive Eidolons for them. That is the single highest-value line item in this patch for low-spenders. Do not sleep on it.

Star Lotto is the outfit draw for Aha's new costume. Cost and pity structure not stated in official materials.

Lore Connections: Aha and the Voracity Hunt

Aha's playable debut ties directly into the Trailblaze Missions around hunting the Voracity leviathan. The Aeon of Elation as a party member is a lore escalation on par with the Nihilux thread, and it raises the question of how HoYoVerse handles Aeon-scale entities in combat without breaking the power fiction.

The Verdict

2026-11-11 is a date to circle. Aha is the headline, but the Affinitive Eidolon upgrades for Acheron, DHIL, and Jing Yuan are the real endgame lever — they lift three established carries without requiring new pulls. Bank the 300 Jades from the codes, claim your free pick, and decide on Aha only after her kit numbers go live.
