Tower of Babel
The game's central objective revolves around fighting upward through the Tower of Babel and surviving increasingly dangerous encounters.
Kernel Hearts Beginner Guide
Kernel Hearts rewards movement, careful dodging, aggressive damage windows, and smart upgrade choices. Each run through the Tower of Babel is an opportunity to learn enemy patterns, improve a build with Mementos and Relics, and push farther before the next attempt.
Learn Your Character's Core Attacks
Start by learning the basic attack sequence and character-specific abilities. Knowing how long each animation lasts makes it easier to attack without getting trapped during an enemy counterattack.
Use Dodging as a Core Combat Tool
Enemy attacks reward active movement rather than standing in place and trading damage. Watch attack animations, dodge out of dangerous areas, and return to offense once the enemy finishes its attack.
Clear Tower Encounters Methodically
Progress through the Tower of Babel encounter by encounter. Prioritize dangerous enemies, avoid being surrounded, and use the available space to separate groups before committing to longer attacks.
Build Around Mementos and Relics
Mementos and Relics shape the strength and direction of a run through passive effects and combat bonuses. Choose effects that reinforce the attacks, abilities, and playstyle you are already using.
Balance Damage and Survivability
Pure damage can clear encounters quickly, but defensive value becomes more important as enemy pressure increases. Combine offensive upgrades with enough survivability to recover from mistakes.
Coordinate in Multiplayer
Kernel Hearts supports cooperative combat, making positioning and target selection especially important. Spread out when attacks cover large areas and focus dangerous targets when the team has a safe damage window.
Treat Every Run as Progress
Later attempts become easier when you recognize enemy attacks, understand your character's safest combos, and identify useful Memento and Relic combinations. Use early runs to learn rather than rushing every encounter.
Quick Tips
- Test attacks and abilities early in a run before encounters become more dangerous.
- Do not spend every movement option immediately; keep an escape available when entering a crowded fight.
- Survival is usually more valuable than forcing a small amount of extra damage.
- A focused build with effects that work together is more useful than collecting unrelated bonuses.
Kernel Hearts Character Tier List
Kernel Hearts is designed around a squad of magical girls with distinct combat styles rather than interchangeable characters. The most useful way to compare the roster is by the role each character fills, how safely that kit deals damage, and how well its strengths combine with run-specific upgrades.

Kernel Hearts Mementos and Relics Tier List
Mementos and Relics are central to run building in Kernel Hearts. Rather than choosing upgrades in isolation, players get better results by stacking effects that support the same combat plan and by balancing offensive power with enough safety to survive later Tower encounters.
Mementos or Relics that directly reinforce a character's strongest attacks, abilities, or repeated combat actions provide the foundation for the most cohesive runs.
Prioritize compatible follow-up effects once a strong central synergy appears.
Reliable Damage Scaling
Priority: HighestConsistent offensive effects are valuable because they improve encounters without requiring narrow activation conditions.
Prefer damage bonuses that work during normal combat over effects that activate only in rare situations.
Survivability
Priority: HighDefensive effects help preserve a run when enemy damage and encounter complexity increase deeper inside the Tower of Babel.
Combine enough defense to survive mistakes with offensive effects that keep encounters from lasting too long.
Effects that support movement or make it easier to maintain pressure can increase both effective damage and safety.
These effects are strongest on characters that already benefit from frequent repositioning.
Conditional Damage
Priority: MediumConditional offensive effects can become powerful when a build consistently satisfies their activation requirement but offer less value when the condition is unreliable.
Take them when the rest of the build already supports the required condition.
Utility Effects
Priority: MediumUtility-oriented Mementos and Relics can smooth out difficult encounters or support a particular team strategy without directly providing maximum damage.
Use utility to solve a specific weakness rather than collecting unrelated effects.
Low-Synergy Picks
Priority: LowAn individually useful effect loses value when it does not interact with the character, current upgrades, or the direction of the build.
Replace scattered bonuses with effects that strengthen the same core strategy whenever possible.
Best Kernel Hearts Builds and Combos
Kernel Hearts lets players shape each run through combat options, Mementos, Relics, and other upgrades found while climbing the Tower of Babel. The strongest setup depends on the tools obtained during a run, so these build archetypes focus on useful synergies rather than requiring one fixed loadout.
Beginner Survival Build
Safe and consistentPrioritize Mementos and Relics that improve survivability or make your most reliable attacks easier to use. Keep a movement option available for escaping Angel attacks instead of committing every tool to damage.
Combo
Safe attack sequence → reposition or dodge → spell when an opening appears → disengage before the enemy counterattack
New players learning enemy patterns and boss mechanics
Aggressive Damage Build
High pressureStack upgrades that strengthen the attacks and spells you are already using effectively. Favor combinations that let several offensive effects contribute during the same damage window.
Combo
Close distance → attack chain → spell during the opening → continue pressure while the target is vulnerable → dodge out
Experienced players comfortable with enemy attack timing
Mobile Hit-and-Run Build
Fast movementBuild around movement and effects that remain useful without forcing long attack commitments. Reposition frequently and punish enemies immediately after avoiding their strongest moves.
Combo
Bait attack → dodge or reposition → quick counterattack → spell → move away before the next pattern
Boss encounters with dangerous close-range attacks
Co-op Burst Build
Team damageCoordinate offensive tools with teammates instead of triggering every ability independently. Use pings and positioning to concentrate damage on the same dangerous enemy or boss.
Combo
Regroup → identify target → avoid major attack → team commits attacks and spells during the same opening
Multiplayer runs and boss damage phases
Kernel Hearts Boss and Angel Guide
Boss encounters test movement, positioning, damage output, and the upgrades collected during a run. Treat each fight as a pattern-learning challenge: avoid committing to long attack sequences until the Angel finishes a dangerous move, then use the resulting opening to counterattack.
Kernel Hearts Progression and Resources
Kernel Hearts combines rewards found during individual runs with progression that carries value beyond a single attempt. Exploring thoroughly, defeating enemies, collecting Lost Wishes and Lost Souls, and using Purifications and permanent upgrades all contribute to becoming stronger across repeated climbs.
Explore Each Run
HighMove through the Tower of Babel while checking available routes and encounters instead of rushing directly forward. Exploration provides more opportunities to fight enemies, collect resources, and find upgrades that strengthen the current run.
Collect Lost Wishes
HighPick up Lost Wishes encountered during progression and treat them as an important part of the game's resource loop. Do not ignore optional rewards when your current build is strong enough to safely obtain them.
Gather Lost Souls
HighContinue accumulating Lost Souls through combat and exploration. Prioritize consistent resource collection over taking unnecessary risks that could prematurely end a productive run.
Use Purifications
MediumIntegrate Purifications into progression as they become available. Consider how each progression choice supports both immediate survival and the longer climb rather than selecting upgrades without a plan.
Invest in Permanent Progression
HighBetween runs, prioritize permanent improvements and unlockables that make future attempts more consistent. Early progression should favor broadly useful benefits rather than upgrades that only support one narrow combat approach.
Push Deeper Into the Tower
End GoalReturn to the Tower with stronger permanent progression and better knowledge of Angel encounters. Repeat the exploration, resource, upgrade, and boss cycle to reach increasingly difficult sections.
Kernel Hearts Multiplayer and Co-op Guide
Kernel Hearts supports both solo play and cooperative runs with up to four players. Multiplayer is most effective when the party stays aware of each other's position, communicates important targets with pings, and avoids having every player commit to the same risky action at once.
Solo and Four-Player Runs
Party SetupThe game can be played alone or with a team of up to four players. Solo runs place every combat and progression decision on one player, while co-op lets the group coordinate positioning and damage across encounters.
Choose the mode that matches whether you want complete control over the run or coordinated multiplayer combat.
Use the Ping System
CommunicationPings provide a fast way to direct teammate attention during exploration and combat. Use them for important enemies, objectives, routes, or anything the whole group should react to quickly.
Ping before committing to a dangerous target so the party attacks together instead of splitting attention.
Build Complementary Loadouts
Team BuildingParty members do not need identical Mementos, Relics, or combat priorities. A balanced team benefits from players developing setups that remain effective in different situations rather than competing for exactly the same role.
Mix safe, mobile setups with more aggressive damage-focused builds.
Synchronize Boss Damage
Boss StrategyDuring Angel encounters such as Gabriel, Hanniel, and Seraph, wait for a reliable opening before multiple players commit their strongest attacks and spells. Coordinated burst windows reduce the time the group spends exposed to dangerous counterattacks.
Survive the boss pattern first, then concentrate team damage during recovery windows.
Stay Within Support Range
PositioningAvoid spreading the party so widely that teammates cannot react to the same threat. Staying reasonably grouped makes pings easier to follow and helps the team focus dangerous enemies quickly.
Spread enough to dodge attacks, but regroup before the next major engagement.
Share the Run Plan
CoordinationBefore difficult encounters, make sure the party is pursuing the same immediate objective. Coordinated exploration, resource collection, and combat decisions make a multiplayer run more consistent.
Use simple priorities: explore, collect upgrades, regroup, then engage the next major encounter.
