BlazBlue Entropy Effect is a 2D action roguelite from 91Act, and it is not a fighting game, which is the first thing most people get wrong about it. It borrows the BlazBlue cast but plays as a side-scrolling run-based action game: Early Access opened on 15 August 2023 and version 1.0 landed on 14 February 2024, with the Steam page listing sixteen playable characters. A run is called Mind Training and moves through five fixed stages: Night City, the Laboratory, the Ruins, Sakura City, and Space Omega.
These tips go beyond the basics. They're the strategies experienced players use to play more efficiently, the hidden mechanics most people miss, and the optimizations that compound over a full playthrough. If you're just starting, check our beginner's guide first.
Essential Tips
1. Understand what you bought: this is a run-based action roguelite from 91Act, not a versus fighting game
Understand what you bought: this is a run-based action roguelite from 91Act, not a versus fighting game. The BlazBlue cast is here, but there is no traditional matchmaking ladder or fighting-game training mode.
2. Tactic Codex slots lock to a family once filled
Tactic Codex slots lock to a family once filled. Deciding early whether a slot is attack, skill, dodge, legacy, or summon is more important than any single upgrade you pick up.
3. Hakumen is the community's standard first unlock because of his parry and super armor, which forgive the reaction errors that end early runs

4. Prototype Analyzers come from Training Objectives and from CL-1's shop at 5000 AP each
Prototype Analyzers come from Training Objectives and from CL-1's shop at 5000 AP each. A failed run still earns AP, so treat unlocks as guaranteed progress rather than luck.
5. In Space Omega, hunt the Elite Enemies before heading to Susano'o
In Space Omega, hunt the Elite Enemies before heading to Susano'o. Each one you beat applies an effect that weakens him, and the labyrinth layout is random so sweep it deliberately.
6. Legacy skills carry between runs and are tied to playing multiple Prototypes, so rotating characters is progress rather than a detour from mastering one
Legacy skills carry between runs and are tied to playing multiple Prototypes, so rotating characters is progress rather than a detour from mastering one.
7. Each stage rolls one of two bosses, which means you will not see every fight in a single run
Each stage rolls one of two bosses, which means you will not see every fight in a single run. Losing to an unfamiliar boss is normal on your first encounter with it.
8. Evotype Talents change positioning goals
Evotype Talents change positioning goals. A talent that pays out for hitting enemies from behind rewires how you approach every fight, so read it before assuming your usual pattern still applies.
9. Later patches added Black Market and Event room types to runs
Later patches added Black Market and Event room types to runs. If you have an older guide open, its room list is out of date.
10. The game shipped guest characters, including ICEY and The Prisoner from Dead Cells, alongside the BlazBlue roster
The game shipped guest characters, including ICEY and The Prisoner from Dead Cells, alongside the BlazBlue roster. If a guide names a character you cannot find, check whether it is DLC or from a later version.
Advanced Strategies
Build Optimization
The difference between an average build and an optimized one is massive. See our builds guide for full breakdowns.
For Ragna the Bloodedge (A-Tier):
- Focus on Mind Training stage order combinations for maximum output.
- Core gear: Attack tactics
- Stat priority: Offensive stats first
For Hakumen (A-Tier):
- Versatile approach that handles any situation.
- Core gear: Skill tactics
- Stat priority: Balanced stats
Mechanic Interactions
Understanding how BlazBlue Entropy Effect's systems interact is where the real optimization lives. Our combat guide covers this in detail.
Mind Training stage order + Tactic Codex slots: Official patch notes describe Mind Training as five phases in a fixed order: Night City, Laboratory, Ruins, Sakura City, and Space Omega. Combined with Tactic Codex slots, upgrades slot into the tactic codex, and community guides describe five families: attack, skill, dodge, legacy, and summon.
Evotype abilities + Prototype Analyzers: Each playable Prototype has an Evotype Ability plus an unlockable Evotype Talent that reshapes how their kit works. When paired with Prototype Analyzers, new characters are unlocked with prototype analyzers rather than by random drop.
Legacy skills between runs scaling: Progress carries between runs through character legacy skills, which is why the game rewards rotating the roster instead of mastering one Prototype. Patch notes have also added run modifiers such as Black Market and Event rooms.
Equipment Efficiency
| Equipment | Best Use Case | Why |
|---|---|---|
| Attack tactics | Ragna, Hakumen, and anyone comfortable fighting at close range | The family that upgrades your basic offense. |
| Skill tactics | Noel and other characters who fight from a distance | Upgrades to special moves and their cooldowns. |
| Dodge tactics | Combo characters such as Es and Taokaka | Turns evasion into an offensive tool through cancels and follow-ups. |
| Legacy tactics | Players building long-term account progress | Tied to the legacy skills that persist between runs and reward playing more than one Prototype. |
| Summon tactics | Runs where you drew weak offensive options early | Adds allied damage that fights alongside you. |
Location Efficiency
Night City (Run phase 1 of 5): The first phase of Mind Training. Community wikis list the Watcher and the Sweeper as the two possible bosses here, and the stage rolls one of them at random.
Laboratory (Run phase 2 of 5): The second phase in the fixed order given by official patch notes. Community listings put the Sand Serpent and the Tree of Origin as the stage's boss pair.
Ruins (Run phase 3 of 5): The third phase, and the point where a run with scattered tactic families starts falling behind. Community wikis name the Defiling Eye and Arakune as the bosses here.
Sakura City (Run phase 4 of 5): The fourth phase. Official patch notes confirm NAN-FIRE BITE as a Sakura City boss, and community listings pair it with Oread. Black Market and Event rooms were added to the run pool by later patches.
Space Omega (Run phase 5 of 5): The final phase, a randomly generated labyrinth ending at Susano'o. Defeating Elite Enemies found along the way applies a debilitating effect to Susano'o, so clearing them first makes the final fight noticeably easier.
Mistakes Even Veterans Make
- Buying it expecting a BlazBlue versus fighting game.
- Spreading tactic slots across every family and ending with a run that does nothing well.
- Hoarding AP instead of buying a 5000 AP Prototype Analyzer.
- Rushing to Susano'o in Space Omega without clearing Elite Enemies first.
- Sticking to one character and missing the legacy skill progression entirely.
Pro Quick Tips
- Understand what you bought: this is a run-based action roguelite from 91Act, not a versus fighting game. The BlazBlue cast is here, but there is no traditional matchmaking ladder or fighting-game training mode.
- Tactic Codex slots lock to a family once filled. Deciding early whether a slot is attack, skill, dodge, legacy, or summon is more important than any single upgrade you pick up.
- Hakumen is the community's standard first unlock because of his parry and super armor, which forgive the reaction errors that end early runs.
- Start with Hakumen, switch to Ragna the Bloodedge when ready
- Invest in Attack tactics above everything else
- Clear areas in order: Night City → Laboratory → Ruins → Sakura City → Space Omega. See our maps guide
- Mind Training stage order + Tactic Codex slots together are stronger than either alone
