Gulu Balls are Roco Kingdom’s main capture tools. Regular, Intermediate, Advanced and Super tiers trade cost for progressively better odds, while attribute and condition-specific balls can improve a suitable encounter. Capture success also depends on the spirit’s remaining HP, innate difficulty, status effects and, according to the Roco Kingdom: World guide, whether you begin from behind. King Ball, Capture Light Ball and Prism Ball are presented as 100% capture options, but their talent, stat and cosmetic benefits are different.
What capture balls are available in Roco Kingdom?
The game’s capture items are generally called Gulu Balls. Guides divide them into four practical groups: standard tiered balls, attribute balls, conditional balls and premium or guaranteed balls. The right choice depends on the spirit’s difficulty, its element pairing, the encounter conditions and how expensive a failed attempt would be.
Standard Gulu Ball tiers
These are the ordinary progression for routine catches. Each step up costs more or is harder to obtain, but is intended to provide a higher baseline chance.
- Regular Gulu Ball: the basic option for common, lower-difficulty spirits.
- Intermediate Gulu Ball: a middle tier for targets that are less cooperative or that you do not want to weaken repeatedly.
- Advanced Gulu Ball: a high-tier standard ball. The Roco Kingdom: World guide reports an additional advantage when the target is below 30% HP.
- Super Gulu Ball: the strongest of the four ordinary tiers in that guide, intended for difficult or valuable targets.
The percentages published for these tiers are estimates, not a universal formula displayed by the game. They should be used to choose a risk level rather than to predict the exact result of one throw.

Attribute balls
The guide describes nine attribute balls, each associated with a paired element combination. An attribute ball is most useful when the wild spirit matches the ball’s element pairing. Because element names, pairings and item availability can change with updates, check the current capture screen for the matching icon instead of relying on an old list of labels.
Conditional balls
Conditional balls gain their value when a particular encounter state is active:
- Water Drop Ball: intended for rainy encounters.
- Ice Ball: intended for blizzard conditions.
- Sleepy Ball: intended for sleeping or nocturnal targets.
- Soft Ball: intended for dungeon encounters.
These items are not automatically better in every fight. Their advantage is tied to the stated weather, sleep, time or dungeon condition, so a standard higher-tier ball may be the better choice when the condition is absent.

| Ball | Reported capture result | Additional association |
|---|---|---|
| King Ball | 100% capture | Amazing talent guarantee in the shiny guide; listed at 240 Roco Diamonds or available through free machine attempts in that guide. |
| Capture Light Ball | 100% capture | No talent bonus is stated. |
| Prism Ball | 100% capture | Associated with Excellent-tier capture and shiny or prismatic outcomes. |
Prices, event rewards, purchase limits and the bonuses attached to these items are volatile. Treat the figures above as guide-reported information and verify the current client before spending currency or using a limited attempt.
How capture accuracy is calculated
No available source provides a complete official equation that converts every spirit’s HP, capture difficulty, status and ball into a current percentage. The published descriptions do agree on the factors that matter:
- Remaining HP: a weakened target is easier to capture. The Chinese Roco Fandom capture article says a target at full HP cannot be captured.
- Innate capture difficulty: some spirits are naturally harder to secure than others, even at the same HP.
- Status effects: sleep and other abnormal conditions improve the chance when the encounter permits them. The same article summarizes abnormal status as doubling capture odds, but that is a guide description rather than a confirmed universal multiplier for every spirit.
- Ball type: standard tier, element match and active condition all alter the starting chance.
- Approach angle: the Roco Kingdom: World guide says approaching from behind before initiating the encounter doubles success chance. Since no official formula corroborates that claim, treat it as a documented strategy to try, not a guaranteed multiplier in every version.
These modifiers work together. A Super Gulu Ball thrown at full HP is not equivalent to the same ball used after safely reducing HP and applying sleep. Conversely, a low HP target can still be difficult if its innate capture difficulty is high.

Two commonly cited sources report different ranges. A 2010 answer from 4399 gives lower theoretical figures for ordinary, intermediate and advanced balls. The newer Roco Kingdom: World guide gives broader, higher ranges and adds a Super tier. They may describe different versions or systems, so do not combine them into one exact progression.

| Ball | 4399 answer (2010) | Roco Kingdom: World guide | How to interpret it |
|---|---|---|---|
| Regular Gulu Ball | 10–15% theoretical | Approximately 10–20% | Baseline estimate; actual odds vary with HP, difficulty and status. |
| Intermediate Gulu Ball | 20–30% | Approximately 25–40% | Mid-tier estimate from sources that may represent different eras. |
| Advanced Gulu Ball | 35–50% | Approximately 40–60%; guide notes a bonus below 30% HP | Use after weakening a difficult target, especially where the guide’s HP condition applies. |
| Super Gulu Ball | Not stated | Approximately 60–80% | Highest ordinary-tier estimate in the newer guide. |
The percentages are approximate ranges, not guarantees. The 4399 figures are explicitly from 2010 and should not be presented as current Roco Kingdom: World rates. The newer ranges are also guide estimates rather than an official universal table.
Best way to improve a normal capture
Use the following sequence when a failed throw would waste time or a scarce ball.
- Start with the encounter safely. Check the spirit’s element pairing, location and whether rain, blizzard, sleep, night or dungeon rules are active.
- Approach from behind when possible. The Roco Kingdom: World guide reports a doubled chance for a backstab approach. Because the claim is not confirmed by an official formula, regard it as an opportunity rather than a promise.
- Lower HP without knocking the spirit out. The capture article states that full-HP targets cannot be captured and that lower HP improves the chance. Stop at the lowest practical HP that your team can control.
- Apply sleep or another useful abnormal status. The 4399 advice specifically recommends sleep or a similar effect after reducing HP. Status effects can be temporary, so throw while the effect is active.
- Match the ball to the situation. Use an attribute ball for the corresponding element pair. Choose Water Drop Ball in rain, Ice Ball in a blizzard, Sleepy Ball for a sleeping or nocturnal target, and Soft Ball in a dungeon when the condition is active.
- Select a tier appropriate to the risk. Regular or Intermediate balls are sensible for common, low-difficulty spirits. Move to Advanced or Super for harder targets, valuable variants or attempts where repeated battles are costly.
- Reserve guaranteed balls for high-value catches. King, Capture Light and Prism Balls remove the ordinary capture-failure risk according to the guide, so they are most efficient when the spirit is rare, an excellent or shiny outcome matters, or another failure would be more expensive than the premium item.
Choosing between attribute, conditional and standard balls
Ball selection is a decision about active bonuses versus dependable baseline strength. An attribute or conditional ball can outperform a lower-tier standard ball when its requirement is clearly active. If the weather changes, the target wakes, or you leave a dungeon, that advantage may disappear. A higher-tier standard ball is easier to reason about when no special condition applies.

- Use a conditional ball only when its weather, sleep, nocturnal or dungeon requirement is visible or reliably true.
- Use Advanced or Super when the target is difficult and no special ball has a confirmed active advantage.
- Use a guaranteed ball when preserving the encounter matters more than conserving premium currency or limited attempts.
Do King Balls guarantee a catch?
According to the newer guide, yes: King Ball is listed as a 100% capture option. That guarantee is separate from its additional talent association. The shiny guide links King Ball with an Amazing talent guarantee and lists a price of 240 Roco Diamonds or free machine attempts. Those availability and pricing details can change after an update, and the current client should be treated as authoritative.

A guaranteed catch does not mean every premium ball has the same secondary outcome. Capture Light Ball is also listed as 100% capture but has no stated talent bonus. Prism Ball is described as 100% capture with Excellent-tier capture and shiny or prismatic associations. Choose among them based on the outcome you want, not only on the shared capture guarantee.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Why a throw can fail even after preparation
The target was at full HP
The capture article says full-HP targets cannot be captured. Damage the spirit first, while keeping enough control to avoid a knockout.
The status wore off
Sleep and other abnormal effects are temporary. If the target wakes before the throw, reapply the effect when possible or use the best available ball immediately rather than assuming the earlier bonus remains.

The special condition was not active
Rain, blizzard, nocturnal, sleep and dungeon bonuses are conditional. Confirm the encounter state at the moment of the throw; entering a different area or changing the weather can remove the intended benefit.

- 【Reduce Safety Risks】Cable tray under desk keeps all plugs away from your kids, no more worry about tripping. Using 2 holes wire tray saves extra space, helps you easily cabling and wire protection. The mesh design is not easy to accumulate dust, but avoids safety accidents caused by messy wires.
The target’s innate difficulty is high
HP reduction and status effects improve odds but do not erase a spirit’s underlying difficulty. Escalate from Intermediate to Advanced or Super, or use a guaranteed ball if the target is valuable enough.
The published percentage was treated as a promise
A 40–60% estimate does not mean every Advanced Ball succeeds between those exact values. The ranges are guide-level approximations from sources that may cover different versions. Expect streaks of failures at any non-guaranteed rate.
Version and availability cautions
Capture mechanics and item inventories can change with updates, events and regional or client differences. The 2010 4399 figures and the newer Roco Kingdom: World estimates should remain labeled by source and era. No cited source establishes a complete current formula for every spirit, and no source proves that the reported backstab or status multipliers apply identically to every encounter. Check the in-game ball description, event panel and capture interface before using a limited item.
