Whether you’re a complete beginner to Skill Builder or an experienced creator looking to master the new system, this guide will take you from basic concepts to advanced techniques. I’ll walk you through each block’s mechanics, provide practical examples, and share pro tips that most players haven’t discovered yet.
What Makes the V1.68 Skill Builder Update Revolutionary?
The December 2025 V1.68 update wasn’t just a minor tweak—it completely redefined what’s possible in Jujutsu Shenanigans custom move creation. Here’s why this update matters:
Key Changes in V1.68:
- New Block Types: Hitbox, Connect, and Velocity blocks add unprecedented control
- Advanced Branching System: Ground and air variants for dynamic moves
- Enhanced Logic Capabilities: Connect blocks enable complex conditional systems
- Improved Movement Control: Velocity blocks with XYZ precision
- Better Combat Flow: Smoother transitions and combo potential
These changes eliminate many of the workarounds players previously used, making skill creation more intuitive while simultaneously opening up possibilities for more complex and polished moves.
Understanding the Velocity Block: Movement Mastery
The Velocity block is arguably the most powerful addition to the Skill Builder system, giving you precise control over character movement during custom moves. Let me break down exactly how it works and how you can use it to create professional-level movement skills.
XYZ Movement System Explained
The Velocity block operates on a simple three-axis system:
| Axis | Movement Direction | Common Uses |
|---|---|---|
| X | Left/Right | Side dashes, strafing attacks |
| Y | Up/Down | Launchers, aerial movement |
| Z | Forward/Backward | Forward dashes, backward escapes |
Pro Tip: Use negative values to reverse movement direction. For example, setting Z to -10 will make you dash backward instead of forward.
Essential Velocity Settings
Time Setting: Controls how long the velocity effect lasts. Most dashes use 0.3-0.5 seconds, while launchers might use 0.8-1.2 seconds.
Fade Setting: Creates smooth acceleration and deceleration. Enable this for professional-looking movement that doesn’t feel abrupt.
Track Setting: Makes movement follow your camera direction. Perfect for omnidirectional dashes that always go where you’re looking.
Hit Value Mechanics
This is where many beginners get confused. The Hit value determines who gets affected by the velocity:
- -1 (Default): Affects only yourself (most common for movement skills)
- 0 or higher: Pushes opponents instead (for knockback attacks)
Practical Velocity Examples
Creating a Basic Dash:
- Set Z to 15 for forward movement
- Set Time to 0.4 seconds
- Enable Fade for smooth acceleration
- Set Hit to -1 (affects only you)
Creating a Launcher:
- Set Y to 20 for upward movement
- Set Z to 5 for slight forward momentum
- Set Time to 1.0 seconds
- Enable Fade for natural arc
Creating Knockback:
- Set Z to -10 (pushes opponent back)
- Set Hit to 0 or higher
- Set Time to 0.6 seconds
- Adjust based on character weight
Hitbox Block Breakdown: Combat Precision
The Hitbox block defines how your custom moves interact with opponents, making it essential for creating reliable attacks and devastating combos.
Core Hitbox Settings
| Setting | Function | Recommended Values |
|---|---|---|
| Size | Determines hitbox dimensions | 5-15 for most attacks |
| Stun | Enemy stun duration | 0.5-2.0 seconds |
| Damage | Base damage dealt | 5-25 for balanced moves |
| Attack Type | Damage category | Melee, Dismantle, Adaptation |
Advanced Hitbox Options
Blockable: Determines if opponents can block your attack. Disable this for unblockable ultimate moves or grab-type attacks.
360 Hit: Makes your attack hit from all directions. Perfect for area-of-effect moves or defensive skills.
Cancel Enemy: Interrupts opponent’s current action when hit. Essential for combo starters and pressure tools.
Ragdoll Settings Explained
Ragdoll Time: How long enemies remain ragdolled. Longer times (2-3 seconds) are great for combo extenders, while shorter times (0.5-1 second) work well for quick follow-ups.
True Ragdoll: Forces full ragdoll behavior without interruption. Use this for cinematic finishers or guaranteed combo setups.
Hitbox Placement Strategies
The timing and positioning of your Hitbox blocks can make or break a custom move:
- Early Hitbox: Place Hitbox early in the timeline for fast attacks
- Delayed Hitbox: Add Wait blocks before Hitbox for charged moves
- Multiple Hitboxes: Use several Hitbox blocks for multi-hit attacks
- Persistent Hitbox: Extend Hitbox duration for area control
Connect Block: Logic-Based Interactions
The Connect block is the most advanced feature in the new Skill Builder system, enabling complex logic-based interactions that were previously impossible. While it has a steeper learning curve, mastering it will set your custom moves apart from the competition.
How Connect Blocks Work
Unlike other blocks, Connect blocks don’t directly affect gameplay. Instead, they act as signal carriers between different parts of your custom move, enabling conditional activation and complex timing systems.
Key Principles:
- Connect blocks must receive a logic signal to activate
- They don’t work directly with logic blocks (this is a common misconception)
- They control activation timing, range, and duration of connected blocks
- They can create branching paths based on conditions
Practical Connect Block Applications
Conditional Activation: Use Connect blocks to trigger effects only when certain conditions are met:
- Distance-based triggers
- Timing-based combinations
- Health-based activations
- Combo requirements
Example: Combo Extension Create a move that only adds extra effects if you’ve already landed a certain number of hits:
- Use Hit Cancel to detect successful hits
- Connect to additional Hitbox blocks
- Only activate if combo requirement is met
Advanced Timing Control: Create complex multi-stage moves with precise timing:
- Main attack connects
- Connect block delays secondary effect
- Conditional activation based on first hit success
Common Connect Block Mistakes to Avoid
- Direct Logic Connection: Don’t try to connect directly to logic blocks
- Missing Signal Source: Ensure something is triggering the Connect block
- Overcomplication: Start simple before attempting complex logic chains
- Timing Issues: Use Wait blocks to fine-tune activation timing
Use When Obtained Property: Instant Activation Magic
This seemingly simple property opens up incredible possibilities for creating cinematic grabs, instant counters, and scripted sequences that feel straight out of the anime.
What Use When Obtained Does
When enabled, this property makes your custom move activate instantly upon acquisition, rather than waiting for manual input. The effect typically happens only once per move acquisition.
Best Use Cases
Grab-Type Moves:
- Instant activation upon obtaining the move
- Perfect for cinematic grab animations
- Can combine with Velocity for dramatic pulls
Counter Attacks:
- Activate immediately when conditions are met
- Excellent for reversal-type moves
- Can be combined with invincibility frames
Cinematic Finishers:
- Trigger automatically when combo requirements are met
- Create dramatic ultimate-style moves
- Perfect for awakening sequences
Implementation Tips
- Combine with Velocity: Add dramatic movement to instant activations
- Use Sparingly: Overuse can make moves feel uncontrollable
- Test Thoroughly: Ensure timing feels natural and balanced
- Consider Balance: Instant activation moves should have clear drawbacks
Advanced Branch System: Ground and Air Variants
The new branching system allows your custom moves to behave differently based on player state, creating dynamic skills that adapt to combat situations.
How Branching Works
The system creates two parallel paths for your custom move:
- Ground Variant: Activates when player is on the ground
- Air Variant: Activates when player is airborne
Strategic Applications
Adaptive Combos:
- Ground version starts combos
- Air version extends aerial combos
- Seamless transition between states
Movement Skills:
- Ground version provides forward dash
- Air version enables aerial mobility
- Creates versatile movement options
Defensive Tools:
- Ground version for ground-based counters
- Air version for air recovery options
- Comprehensive defensive coverage
Branch System Best Practices
- Maintain Consistency: Keep similar timing between variants
- State-Specific Advantages: Each variant should excel in its environment
- Smooth Transitions: Ensure moves flow naturally between states
- Balanced Power: Avoid making one variant clearly superior
Pro Strategies and Advanced Techniques
Now that you understand the basics, let’s dive into the advanced techniques that will make your custom moves truly exceptional.
Combo Building Mastery
Stun Stacking: Use multiple Hitbox blocks with carefully timed stun durations to create extended combo opportunities:
- First Hitbox: 1.0 second stun
- Follow-up attack: 0.8 second stun
- Finisher: 2.0 second stun for setup
Velocity Chains: Chain multiple Velocity blocks for complex movement patterns:
- Initial dash (Z: 15, Time: 0.3)
- Arc movement (Y: 10, Z: 5, Time: 0.5)
- Final positioning (Z: -5, Time: 0.2)
Advanced Connect Block Logic
Multi-Condition Triggers: Create moves that activate only under specific circumstances:
- Health condition check
- Distance verification
- Combo counter requirement
- Timing window validation
Dynamic Damage Scaling: Use Connect blocks to modify damage based on conditions:
- Base damage for normal situations
- Increased damage during awakening
- Critical hit conditions
- Combo multiplier effects
Professional Polish Techniques
Animation Synchronization: Align your Hitbox and Velocity blocks perfectly with animations:
- Study frame data carefully
- Use Wait blocks for precise timing
- Test with different character models
- Ensure consistency across variants
Sound Integration: Enhance impact with perfectly timed sound effects:

Frequently Asked Questions
How do I access the Skill Builder in Jujutsu Shenanigans?
To access the Skill Builder, enter Build Mode and place down a Moveset, Awakening, or Special Block. Select “Custom” from the move list to open the Skill Builder interface. From there, you can access the Timeline, Conditions, and Properties tabs to create your custom moves.
What’s the difference between Velocity and Hitbox blocks?
Velocity blocks control character movement using XYZ coordinates, while Hitbox blocks define how attacks interact with opponents. Velocity is for movement (dashes, launches), while Hitbox is for combat (damage, stun). They can be combined for complex attack-movement combinations.
Why won’t my Connect block work?
Connect blocks require a logic signal to activate and don’t work directly with logic blocks. Ensure you have a proper signal source and that the Connect block is positioned correctly in your timeline. Try testing with simpler connections first before attempting complex logic chains.
How do I make moves that work differently in the air vs on ground?
Use the Branch system to create separate Ground and Air variants of your custom move. Each variant can have its own timeline with different blocks, allowing the same move to behave differently based on whether you’re airborne or on the ground.
What are the best practices for balancing custom moves?
Start with conservative damage and stun values, test extensively against different characters, and consider both offensive and defensive applications. Good custom moves should have clear strengths and weaknesses, and shouldn’t completely overshadow base game moves.
How can I make my custom moves feel more professional?
Focus on timing precision, animation synchronization, appropriate sound effects, and smooth transitions between different move phases. Test your moves extensively and refine them based on feedback. The best custom moves feel natural and intuitive to use.
