Honkai Star Rail 4.5 Four-Team Event Leak Guide

A Honkai: Star Rail Version 4.5 beta leak describes a new event that asks players to prepare four lineups for a sequence of increasingly difficult battles. The leaked rules mention trial characters, score improvement, recovery between battles, and an allowance of up to 50 attempts per day. The interface has already generated discussion because it appears to test roster breadth rather than only one optimized team.

None of this is final official event information. Version 4.5 remains future content as of July 28, 2026, and beta wording, scoring, trial rosters, enemy lineups, attempt limits, and rewards can change. The leaked image is also translated material, so individual terms may not match the eventual English client.

This guide explains what the current leak actually indicates, what it does not prove, and how players can prepare without spending Trailblaze Power or Stellar Jade on unsupported assumptions.

Leak Status and Current Evidence

The available material is a beta event image attributed through leak channels rather than an official HoYoverse announcement. It presents a mode description and interface elements, not a complete live event manual.

The translated rules indicate that Trailblazers will form four teams, face four consecutive battles that become progressively more difficult, and attempt to achieve higher scores. After each battle, characters reportedly recover HP and Energy. The event is also described as providing trial characters and allowing 50 attempts per day.

Those points are useful, but they leave major questions unanswered. It is unclear whether players manually control every battle, whether some results are simulated, how each team's score is calculated, whether characters can appear in more than one lineup, and what rewards correspond to score thresholds.

What the Leaked Rules Appear to Say

Leaked Element	Current Interpretation	Still Unconfirmed
Four lineups	Players prepare four teams for the event sequence	Whether characters and Light Cones are locked across teams
Four consecutive battles	Difficulty increases from one battle to the next	Enemy lists, weaknesses, cycles, and scoring formula
HP and Energy recovery	Characters recover after each battle	Full recovery, partial recovery, or mode-specific values
Trial characters	The event supplies characters for participation	Builds, Eidolons, Light Cones, and which teams can use them
50 daily attempts	Players can repeat the mode many times per day	What consumes an attempt and whether failed setup previews count
Higher-score objective	Repeating can improve performance	Reward thresholds, ranking, and score cap

The distinction between “four teams” and “four consecutive battles” needs special attention. The current translation suggests four lineups are part of the event, but it does not prove that all sixteen character slots must come from the player's own roster. Trial characters may reduce the ownership requirement substantially.

Why This Event Could Test Roster Breadth

Most Honkai: Star Rail endgame planning revolves around two teams, with some modes favoring specialized mechanics or additional variations. A four-lineup event potentially doubles the number of active formations. That increases pressure on sustain units, universal supports, Light Cones, Relic sets, and characters able to function with less contested teammates.

However, an event can display four team slots without demanding four fully built endgame teams. Trial characters may provide cores, battles may use fixed buffs, or the mode may estimate performance differently from Memory of Chaos. The difficulty and reward thresholds determine whether roster breadth is a hard requirement or simply an optimization opportunity.

The best preparation is therefore to improve functional coverage rather than trying to build eight new characters before official rules exist.

First Preparation Step: Roster Inventory

Create a roster list by role, not by damage-ranking position. Mark available damage dealers, amplifiers, debuffers, action manipulators, sustain units, Break specialists, follow-up enablers, DoT enablers, and flexible sub-DPS characters.

Then identify contested units. A support used by three possible carries cannot serve all four lineups if duplication is forbidden. A single premium sustain may be excellent, but a four-team mode exposes the condition of the second, third, and fourth survival options.

Do not count a character as ready merely because they are level 80. Check Traces, Light Cone level, key Relics, Speed tuning, and whether the intended team reaches a functional rotation.

Four Teams Do Not Need Four Identical Cores

Trying to copy one meta template four times will create impossible support conflicts. Instead, build teams around distinct engines.

One lineup may use a hypercarry with two dedicated supports. Another may rely on Break and Super Break interactions. A third may use follow-up attacks, counters, or summons. A fourth may use DoT, dual damage dealers, or trial characters supplied by the event.

The exact archetypes depend on the account and future enemy weaknesses. The point is independence. Each team should have a way to generate Skill Points, survive, reach its main damage window, and exploit the event's current stage condition.

A lower-cost archetype can be valuable because it leaves contested supports for a team that needs them more.

Sustain Coverage Is the First Bottleneck

Four teams immediately raise the question of sustain. Players may own several Preservation and Abundance characters but only have two with complete builds. The leaked recovery between battles does not remove the need to survive each battle.

Before building a new damage dealer, inspect available sustain units. Level their Light Cones, unlock essential Traces, and give them enough Speed, Effect RES, DEF, HP, healing, or Energy Regeneration to perform their actual role. The correct stats depend on the character.

Do not force one sustain onto every possible team plan. Match cleansing, shields, healing, aggro, and emergency recovery to the enemy mechanics once those enemies are known.

If the event provides trial sustain characters, personal coverage may matter less. That is why waiting for the trial list is important.

Support Distribution

Universal supports become scarce across four lineups. List what each damage dealer truly requires. Some need action advancement, some need Weakness Break support, some need debuffs, and others mainly need Skill Points or Energy.

Do not assign the strongest support to the strongest carry automatically. If that carry remains functional with a substitute while another team collapses without the premium support, the substitute creates more total event value.

Speed tuning must be checked after redistribution. Moving a support changes turn order, buff uptime, and Skill Point flow. Save team presets with notes rather than assuming characters can be swapped freely without Relic changes.

Light Cone Conflicts

Players often own enough characters but not enough leveled Light Cones for four simultaneous teams. If the event prevents sharing, every planned character needs a real equipped option.

Audit by Path. Identify one primary and one backup Light Cone for each active role. Level broadly useful options first. Do not superimpose or consume a flexible Light Cone merely to improve one speculative setup.

Trial characters may arrive with fixed equipment, which can free personal Light Cones. The live event interface should show whether trials can use player equipment or locked builds.

Avoid assuming that a Light Cone displayed in a leaked screenshot is a reward or required item. Interface images often use account inventory examples.

Relic Preparation Without Over-Farming

A four-team event can create pressure to farm many new sets, but functional mixed sets are often enough for backup characters. Prioritize correct main stats, Speed breakpoints, and essential Energy Regeneration before chasing perfect four-piece combinations.

Use saved Relics carefully. If simultaneous lineups lock equipment, one premium Speed boot cannot exist on two teams. Create a conflict list for rare Energy Regeneration ropes, elemental spheres, high-Speed pieces, and Crit bodies.

Do not spend Self-Modeling Resin or large amounts of Trailblaze Power based only on the leak. Wait for official enemies, buffs, and reward thresholds. The event may provide trial characters that solve the weakest slot.

Interpreting HP and Energy Recovery

The leak states that HP and Energy recover after each battle. This could reduce the penalty for finishing a battle at low health or empty Energy, but the exact amount and timing are essential.

If recovery is full, teams can spend Ultimates aggressively near the end of each battle without sacrificing the next one. If recovery is partial, players may need to manage resources. If each lineup fights only one battle, the wording may describe a broader stage sequence rather than continuity for one team.

Do not build a rotation around guaranteed full Energy until the live rule gives a number. When beta footage appears, watch the actual Energy bars between battles rather than relying only on translated text.

Understanding the 50 Daily Attempts

Fifty attempts per day suggests the event encourages repeated optimization and gives players room to improve scores. It does not necessarily mean players must complete 50 full runs.

The key questions are what consumes an attempt, whether exiting early counts, whether changing one team restarts the entire sequence, and whether attempts are shared across stages. If each attempt is lengthy, 50 may be a safety ceiling rather than an expected daily workload.

Players should not turn the allowance into a quota. Complete enough runs to secure desired rewards, then stop unless score improvement is personally enjoyable. A large attempt cap can protect experimentation without demanding maximum use.

Trial Characters and Accessibility

Trial characters are the most important accessibility detail in the leak. They can let new or returning players participate without owning sixteen fully built characters. Their quality will determine how much the event tests ownership versus decision-making.

Inspect trial Eidolons, Traces, Light Cones, Relics, and Speed. A trial character may be stronger or weaker than a personal copy. Some events allow mixing trials with owned units; others provide complete preset teams.

Use trial units to fill roster gaps, not automatically replace a well-built personal character. Compare rotations and score. If trials are tied to specific stages, save personal supports for the teams without assistance.

Score Improvement Strategy

When the mode opens, establish a baseline before optimizing. Use the recommended or obvious teams, complete all four battles, and record total score, individual team score, remaining cycles or time, and failed mechanics.

Then change one variable at a time. Move one support, adjust one Speed value, replace one sustain, or change one Light Cone. If several things change simultaneously, the source of improvement becomes unclear.

Prioritize the weakest team. Increasing an already dominant team by 5% may add less total score than preventing a fourth team from collapsing. Four-lineup modes reward balanced competence.

If scoring includes survival, remaining HP, breaks, or objectives rather than only damage, adapt to the actual formula.

Possible Auto-Battle or Simulation Element

Community discussion around the leaked interface has raised the possibility that some combat or scoring may be simulated or automatically estimated. The current image does not settle this conclusively.

If the mode uses automatic combat, AI targeting, Ultimate timing, and team order become more important. Characters that require precise manual timing may perform differently. If players manually control every battle, mechanical execution remains central.

Wait for gameplay footage or official instructions before describing the mode as an auto-battler. The safe statement is that the leaked event prepares multiple lineups and calculates performance across consecutive challenges; the exact control method remains unconfirmed.

Pull Planning and Stellar Jade

A four-team interface can create fear that the account suddenly needs more characters. Do not pull for roster quantity before rewards and trial support are known. A limited event may be designed for broad participation and could supply enough trials for completion.

Pull decisions should remain tied to long-term account value, preferred characters, established endgame needs, and guaranteed cost. One event should not override a broader banner plan.

Players with an existing Oneiric Shard plan can compare Topuplist and the dedicated Honkai: Star Rail top-up page. Confirm the account, server, product, and delivered currency. Do not spend because an unfinished beta screen displays four team slots.

A Safe Pre-4.5 Upgrade Order

Use this order while details remain unconfirmed:

Finish levels and Light Cones for characters already used in core content.
Unlock essential Traces on backup sustains and supports.
Assemble functional Relic sets from existing inventory.
Create four provisional teams without spending rare materials.
Wait for official Version 4.5 event rules and trial characters.
Upgrade the specific bottleneck revealed by the live mode.

This order produces account-wide value even if the event changes or is easier than expected.

Questions the Official Reveal Must Answer

The official announcement or live tutorial needs to clarify:

Whether all four teams are used in one attempt.
Whether characters, Light Cones, and Relics can be shared.
Whether battles are manual, automatic, or simulated.
Exact HP and Energy recovery values.
What consumes one of the 50 daily attempts.
Trial character builds and restrictions.
Score formula and reward thresholds.
Event dates and server reset time.
Whether attempts or rewards have weekly limits.
Whether later stages change enemy weaknesses.

Until those answers exist, detailed “best four teams” articles are premature.

Common Leak Mistakes

Do not present Version 4.5 beta material as an official global announcement. Do not call 50 attempts a daily requirement. Do not assume sixteen owned characters are mandatory. Do not promise full HP and Energy recovery without the final values. Do not name rewards that have not been shown.

Other mistakes include building several characters solely for the event, treating translated wording as final localization, and combining separate beta revisions. Date every leak and revise conclusions when the build changes.

Final Assessment

The current Version 4.5 leak points toward a roster-breadth event with four lineups, increasingly difficult consecutive battles, trial support, repeat attempts, and score optimization. That is enough to begin an account audit, but not enough to justify new pulls or narrow pre-farming.

Prepare backup sustain, level flexible Light Cones, organize usable Relics, and map support conflicts. Then wait. If the final event supplies strong trials or lenient completion thresholds, many accounts may need only good distribution rather than sixteen premium builds. If it demands deeper ownership, the live rules will reveal the exact bottleneck.

FAQ

Is the four-team event officially confirmed?

No. The information discussed here comes from Version 4.5 beta leak material and can change before an official announcement.

Does the event require sixteen owned characters?

That is not confirmed. The leak mentions trial characters, which may fill some or many lineup slots.

Are there really 50 attempts per day?

The translated beta rules mention 50 daily attempts. What consumes an attempt and whether the number remains final are unknown.

Will HP and Energy fully recover after every battle?

The leak states that HP and Energy recover, but the exact amount and implementation should be verified in the official rules or live client.

Should I top up or pull for more characters now?

No decision should be based solely on a beta image. Players with an existing plan can compare Topuplist and the Honkai: Star Rail recharge page, but should wait for official rules and trial rosters.

What is the safest preparation?

Level flexible Light Cones, improve backup sustain and supports, organize Relic conflicts, and create four provisional teams without spending rare resources.
