ULTIMATE 5⭐Selector Guide I New Units + E1-E6 Dupe Tierlist I Chaos Zero Nightmare

Storyline / Context

• The video centers on a “Half Anniversary Selector” available during a login event.
• It’s claimed on login day 3 via the Half Anniversary menu.
• The selector pool is expanded with characters such as Haruyuki Shizuru, Naja, and Ninetail Erina.
• It also references Reggie’s upcoming unit/dupe tier guidance, implying the event helps players obtain key new units for future content like Chaos Zero / Nightmare runs.

Gameplay Highlights & Key Takeaways

Universal guidance

• New characters > dupes
  • The speaker emphasizes that getting missing characters is usually better than investing into duplicate copies.
  • This strengthens your roster options for more team compositions and future strategies/buffs.
• You can still pick favorites, but the “maximize account power” mindset is:
  1. Fill holes first
  2. Then refine and optimize

Selector baseline tier logic (what to pick)

The tier logic is organized into three main categories:

• “Nine” tier (special/priority)

  • If you don’t have Nine, pick her immediately.
  • She’s described as a top hyper-carry—she “hits the hardest,” and defense-based damage dealers are less common.

• S Tier (supports)

  • Mostly reserved for support units because they enable more team comps and make certain strategies workable.
  • Some supports are described as “required” so that other units can truly perform.

• A Tier (top picks once you’re covered)

  • If you already have Nine, the speaker highlights priority supports/damage boosters such as:
    • Aoleus
    • Naja
    • Typhaera

The “most valuable” support/damage-boosting quartet

Per the video, these four are the highest-impact picks:

• Aoleus

  • Best “singular-hit damage booster.”
  • Noted as extremely strong for single big hits.

• Naja

  • Best for multi-hit / repeated attacks damage boosting.
  • Also easy to use in Chaos runs via attunement:
    • Stacks gained from draws without spending AP for her.

• Typhaera (sometimes compared to “Mika 2.0,” with that comparison noted as debatable)

  • Brings:
    • Healing + shielding
    • High AP generation (if built/played correctly)
    • Two damage-boosting mechanics (via triangle effect and purple card)
  • Strong synergy with units that rely on big burst hits (Nine/Rita/Typhaera interactions are mentioned).

“No wrong way” conclusion (within reason)

• Beyond the strongest recommendations, you likely won’t regret choosing among these top-value options.
• Playstyle preference matters once your essentials are covered.

Dupe (E1–E6) Strategy & When It Matters

E1 (early awakenings)

• Core principle: E1 value depends on how important a character’s purple card is to their kit.
  • If the kit revolves around that purple card, dupes/E1 become much more meaningful.
• The video frames E1 as something to consider mainly for characters you love and plan to keep using.
• Examples of E1 impacts mentioned:
  • Aoleus: improved purple card retention/utility
  • Typhaera: better purple card stacking (higher ceiling) and help toward later awakenings
  • Nine: E1 targeting/control quality matters even if she’s strong without it
  • Rita: AP gains
• “Ceiling vs necessity” warning:
  • For some lower-tier E1s, the change is nice but not game-changing.

E2 (end of “reasonable investment”)

• E2 is where most players don’t need to chase further dupes.
• After E2, dupes are mostly for favorites or gem “splurges.”
• Example E2 upgrades described:
  • Haru: enables using a key damage card (Anchor Shot) even when AP isn’t enough
  • Multiple units gain new mechanics/cards that improve:
    • damage
    • consistency
    • debuffs
    • retention/chance effects
    • ramping

E3 (generally not worth chasing alone)

• Guidance:
  • Don’t hunt E3 unless you’re planning to push further into E4/E5/E6.
• Reasoning:
  • E3 typically buffs the ultimate, but the ultimate is used once per battle, and the gain is mostly damage-only and hard to scale endlessly.
• Slight exceptions:
  • Oleana/Rita get E3 benefits that affect how abilities function (e.g., softer upgrades or next-attack damage setups).

E4 (damage buff / stacking focused)

• E4 is framed as mostly a damage buff that leverages stacking mechanics or internal kit interactions.
• Key point:
  • No E4 is “required,” and you can’t realistically afford everyone to E4.
• Typhaera E4 is highlighted as unusually team-wide oriented, supported by:
  • attack cards
  • order cards
  • defense-based damage considerations

E5 (small multiplier, big return for high-base-damage kits)

• Simple explanation:
  • E5 increases the damage multiplier.
  • The speaker describes base damage × multipliers, with E5 boosting a multiplier from 1.2 to 1.26.
• Rule of thumb:
  • Characters with higher base damage benefit more from E5.
• Big E5 value group mentioned:
  • Nile, Tera, Rita, Rin, Kayron, Haru

E6 (transformative “dream” awakenings)

The strongest E6 transformations listed:

• Nine

  • Adds a final damage multiplier (+15% to final damage added).

• Liu Kang

  • E4 scaling improvements
  • A new “truck-hitting” bullet-style card.

• Haru

  • Reduces the penalty for using Anchor Shot below intended cost:
    • 40% less damage becomes 20% less

• Typhaera

  • Her triangle effect no longer disappears when using her own cards
  • Stacking cap increases, enabling her main DPS role more strongly

• Rin

  • Morale for herself and the whole team.

• Chiron

  • Access to more debuffs (“debuffing machine”).

• Yuki

  • Increases E4 scaling.

• Naja

  • Extra damage hit and healing scaling based on amount of predations used in a turn
  • Can become a high hit-count “machine gun” style

• Rita

  • Doubles the effect of Chrono Ascension
  • Adds fixed-damage extra hits based on consumed Chrono Ascension
  • Potentially creates machine gun-style output

• Shizuru

  • Additional hit on Shadow of the Moon becomes more noticeable depending on how often it’s used
  • Stack vs spam playstyle considerations are mentioned

Closing stance:

• Don’t treat E6 as a must—it’s more of an aspirational goal; most characters don’t require it to succeed.

Key Tips / Strategy Summary

• Pick new units first, not dupes (for roster flexibility and strategy coverage).
• If you don’t have Nine, choose Nine from the selector.
• If you do have Nine, prioritize high-value supports/damage boosters:
  • Aoleus (single-hit damage boost)
  • Naja (multi-hit/repeated attack boosting + Chaos-friendly attunement gameplay)
  • Typhaera (healing + shielding + AP generation + burst damage scaling/team utility)
• E1 value depends heavily on how central the character’s purple card is.
• E2 is usually the stopping point for most players; chase dupes mainly for favorites.
• E3 is generally inefficient unless you plan to go into E4/E5/E6.
• E4 is for damage stacking/interactions—avoid spreading resources too thin.
• E5 rewards high base-damage kits.
• E6 is the biggest role-changing breakpoint—especially for Nine/Typhaera/Naja/Rita and others listed—but is otherwise optional.
