Roblox: Jojo’s Bizarre Incremental has received a major content update featuring a complete combat rework, an expanded skill tree system, a new collection index, and training manuals that replace traditional stat grinding. This update, covered across several patches since the Easter event, introduces meaningful changes to how stands scale, how status effects interact, and how players progress their stats. Key additions include the Index system, which rewards players for collecting every ability from specific parts (Stardust Crusaders, Diamond is Unbreakable, Golden Wind, Stone Ocean, Steel Ball Run, JoJolion, and non-canon stands) with bonuses such as inventory capacity, yen gain, XP gain, luck increases, and global damage boosts. The skill tree rework allows stands to be upgraded individually (up to approximately 5x damage multipliers), compensating for an across-the-board base damage nerf. A new training manual system replaces Strange Arrows and Green Babies for stat progression, allowing players to spec into health, speed, stamina, strength, willpower, and stand-specific stats like power and precision. Additionally, eight new traits (including Siphoning, Shattering, Dominating, Infectious, and Junkie), counter mechanics (predict, negate, and reflect damage), and calamity as the strongest damage-over-time effect fundamentally change combat strategy. World bosses now have defense stats, and the fusion stand system (e.g., Wonder of You + Chikawa) requires upgrading both base stands to maximize fused stand skill trees.
Index Collection System: Part-by-Part Bonuses
The Index is a new progression system that rewards players for collecting every ability (stands and styles) from specific parts of the Jojo franchise. You do not need to obtain stands through gameplay alone—trading counts, as long as the stand is in your inventory.
Complete Index Bonuses Breakdown
| Part / Category | Reward | Notable Missing Stands |
|---|---|---|
| Phantom Blood / Battle Tendency (Styles) | 10% Yen gain | Boxing, Hamonism |
| Second Part (Styles) | 10% XP gain | Cyborg, Pillar Man, Ultimate Life Form |
| Stardust Crusaders | +5 Inventory Capacity | Star Platinum |
| Diamond is Unbreakable | 1% Luck increase | Unknown (possibly boss stand) |
| Golden Wind | 5% Extra Damage | Metallica |
| Stone Ocean | +5 Inventory Capacity | – |
| Steel Ball Run | 1% Luck increase | The World, Tusk Act 4, Love Train |
| JoJolion | 5% Global Damage | Wonder of You |
| Non-Canon | +5 Inventory Capacity | King Crimson, Star Platinum Over Heaven, The World Over Heaven |
| Event Collection | No buffs | Gojo, Chari Requiem, Chikawa |
Strategic Priority for Index Completion
The content creator recommends prioritizing:
- Luck increases (Diamond is Unbreakable, Steel Ball Run)
- Global damage bonuses (JoJolion, Golden Wind)
- Inventory capacity (useful but lower priority)
“Honestly speaking, the inventory capacity isn’t that useful. So I wouldn’t really aim for those. I would aim for the luck and global damage first.”
Skill Tree System: Stand-Specific Upgrades
Every stand now has a unique skill tree accessible through the Index. These trees cannot be upgraded for styles—only stands.
How Skill Trees Work
Each stand’s skill tree includes:
- Damage multiplier upgrades (scales up to approximately 5x)
- Status effect modifiers (e.g., bleed → hemorrhage)
- Damage reduction (e.g., 20% incoming damage reduction)
- Armor penetration (e.g., 25% armor penetration)
- Status duration manipulation (adds or removes turns)
Example: Chikawa Skill Tree
| Upgrade | Effect |
|---|---|
| Cry | 25% armor penetration |
| Pajama Resilience | Reduces incoming negative stats duration by 1 turn |
| One Turn | Increases status durations applied to enemies by 1 turn |
| Wheat Worker | Upgrades bleed to hemorrhage |
| Base Damage Multiplier | Increases to 5x (when maxed) |
| General | Reduces incoming damage by 20% |
Skill Tree Points Acquisition
- Earn prestige points upon prestiging
- High-prestige players (e.g., 800+) can max out multiple stands
- Example: Player maxed King Crimson Requiem, Golden Experience Requiem, Tusk Act 4, Wonder of You, and Chikawa, with 225 points remaining
- Approximately 4 stands can be maxed with ~200 points
Fusion Stand Skill Trees
For fusion stands (e.g., “Chikawa of You” = Wonder of You + Chikawa):
- Branch A moves scale with the first base stand’s skill tree
- Branch B moves scale with the second base stand’s skill tree
- To max a fusion stand, you must upgrade both base stands
Example:
- “Chikawa” part of the fusion → upgrades certain moves
- “Wonder of You” part → upgrades the remaining moves
Base Damage Nerf
The update included a global base damage nerf for all stands. However, the skill tree system compensates by allowing stands to eventually reach comparable or higher damage through upgrades.
“They nerfed everyone’s base damage. So everyone will be doing slightly lower base damage at the start but it doesn’t really matter because the skill tree buffs it eventually.”
Training Manuals: The New Stat System
The stat progression system has been completely overhauled. Strange Arrows and Green Babies no longer grant stats.
New Stat Categories
| Stat Type | Manual Category |
|---|---|
| Health | Training Manual |
| Speed | Training Manual |
| Stamina | Training Manual |
| Strength | Training Manual |
| Willpower | Training Manual |
| Stand Power | Advanced Training Manual |
| Stand Precision | Advanced Training Manual |
| Stand Potential | Advanced Training Manual |
How It Works
- Training Manuals drop from various activities (including world bosses)
- Use them to directly increase specific stats
- No more repetitive training minigames
- All stats can be maxed over time
“Now you don’t have to hit the training thing and increase that slowly. You can spec into every single stat.”
Combat Rework: New Mechanics
Counter System
Counters now allow players to:
- Predict incoming attacks
- Negate damage
- Reflect damage back to the attacker
Cleanse & Status Effects
- Cleanse mechanics were added (details in-game)
- Status effect priority system introduced
Calamity: The Strongest Damage-Over-Time (DOT)
Calamity is now the highest-tier status effect in the game.
How it works:
- When multiple DOTs are applied, the game prioritizes the highest one
- Calamity overrides all other DOTs (burn, poison, bleed, etc.)
- If you apply Calamity, it deals damage instead of other status effects
“If you hit them with calamity, it kind of overrides everything and it just deals calamity instead because I think that’s the highest form of DOT that you can proc onto anything.”
Wonder of You Rework
Previously: Random effect for 5 turns
Now: Directly applies Calamity
Result: Calamity is “really overpowered” and very strong for DOT builds.
New Traits (8 Total)
Eight new traits were added. Below is a ranking based on the content creator’s analysis.
| Trait | Rarity | Effect | Verdict |
|---|---|---|---|
| Dominating | Mythic? | Status effects ignore 50% of armor | Best – Essential for DOT builds |
| Infectious | – | Passes status effects to next enemy at half duration | Good for crowd clearing |
| Junkie | Legendary | More debuffs = more damage | Niche – “kind of trash” |
| Siphoning | – | Steals 10% of drain energy/stamina when attacking | Useless |
| Shattering | – | Exhausts enemies twice as fast | Not useful – “meh” |
| Remaining 3 | Legendary | Not detailed in video | Lower priority |
Recommended Trait for DOT Builds
“Dominating is the best for the 50% bypass armor on DOT. Do aim for that if you want to go for more DOT build.”
Synergy note: Chikawa of You (Wonder of You fusion) may benefit significantly from Dominating due to Calamity application.
World Boss Changes
Defense System Added
World bosses now have defense stats, making them harder to kill.
Before update: 3 turns to defeat a world boss
After update: Approximately 8 turns
Drops
World bosses drop:
- Training Manuals (basic)
- Advanced Training Manuals (for stand stats)
Endless Dungeon & Unique Boxes
Floor Progression
- Player reached floor 1,200+ in endless dungeon

Prestige & Endgame Scaling
Current State
- Player has maxed: King Crimson Requiem, Golden Experience Requiem, Tusk Act 4, Wonder of You, Chikawa
- 225 skill tree points remaining
- Goal: Reach 800+ prestige for even higher stat scaling
Philosophy on “Strongest Stand”
The content creator explicitly refuses to provide tier lists or answer “best stand” questions because:
“There’s no stronger stand. I feel it’s really just up to how you play the game and how many prestiges you have. Technically, anything is the strongest if you have enough prestiges.”
With the damage multiplier system changing everything, players should consult the Index and decide for themselves.
What’s Missing / Criticisms
| Issue | Details |
|---|---|
| Lack of new playable content | Mostly system reworks, no new dungeons or modes |
| Some Index requirements unclear | Creator doesn’t know what they’re missing for Diamond is Unbreakable |
| Traits underwhelming | Only Dominating stands out; others are “meh” or “trash” |
| No tier list support | Developer/creator refuses to provide meta rankings |
Patch Summary Table
| Feature | Summary |
|---|---|
| Index Collection | Rewards for collecting all stands/styles per part |
| Skill Trees | Stand-specific upgrades (5x damage multiplier cap) |
| Training Manuals | Replace Strange Arrows/Green Babies for stat grinding |
| Combat Rework | Counters, cleanse, Calamity as strongest DOT |
| New Traits | 8 added; Dominating is the best (50% armor bypass on DOT) |
| World Bosses | Now have defense; ~3 turns → ~8 turns |
| Fusion Stands | Require upgrading both base stands |
| Base Damage | Nerfed globally, but skill trees compensate |
| Prestige | Earn points to fill skill trees; high prestige = more maxed stands |
Final Verdict
| Aspect | Rating |
|---|---|
| Skill Tree Depth | ⭐⭐⭐⭐☆ (meaningful customization) |
| Index System | ⭐⭐⭐⭐☆ (good long-term goals) |
| Combat Rework | ⭐⭐⭐☆☆ (Calamity is strong, counters add depth) |
| New Traits | ⭐⭐☆☆☆ (only Dominating is exciting) |
| Playable Content | ⭐⭐☆☆☆ (mostly system updates, no new modes) |
| Overall | Solid mechanical overhaul lacking new activities |
“Quite a decent big update. But in terms of other playable content, there’s not really anything.”
