Roco Kingdom Buzzlings, Bumbelle and Bumbora: Full Evolution Line, Stats and Swarm Rally Trait

A group of tiny bees carrying a floating hive might seem harmless, but they become much more organized as they evolve. In Roco Kingdom, Buzzlings grows into Bumbelle and eventually Bumbora, a Bug / Wing-class Jini that relies on teamwork rather than individual strength. The entire line shares Swarm Rally, a trait that increases Attack, Defense and Speed based on how many other Bug-class Jinies are on the lineup. Here is how each stage evolves, how their stats improve and why building the right team is essential to making the most of this unusual bee colony.

The evolution line

Buzzlings evolves into Bumbelle at Level 21, while Bumbelle evolves into Bumbora at Level 38. All three stages belong to the Bug and Wing classes.

1. Buzzlings (No. 082, Bug / Wing): A small group of bee-like Jinies that carry a floating hive behind them. The hive moves almost as naturally as the bees themselves, with every movement perfectly synchronized. Researchers suspect that pheromones or some mysterious form of magic helps coordinate their actions.
2. Bumbelle (No. 083, Bug / Wing): The colony develops a more recognizable queen, accompanied by two smaller worker Buzzlings. The energy pulses surrounding the queen's lower body are believed to help coordinate her attendants. Her eyes turn red during battle, and she possesses an exceptionally sharp stinger.
3. Bumbora (No. 084, Bug / Wing): The final evolution takes the appearance of an elegant queen bee wearing a flowing golden cloak and crown-like ornaments. Two attendants remain constantly by her side. Her refined appearance leaves a lasting impression, and her graceful style has even inspired numerous fashion designs.

The evolution line progresses from a small, tightly coordinated swarm into a fully developed queen surrounded by loyal attendants.

Unlike many other Jinies, the colony's identity remains central throughout evolution, with its members continuing to move and fight together.

All three stages belong to the Insect and Sky Egg Groups.

Bumbora also has a separate Alpha form called Buzzara, which is distinct from the regular level-based evolution line.

Trait: Swarm Rally

For each other Bug-class Jini on the lineup, gains 10% Attack, Defense and Speed upon entry.

All three stages share this trait. Swarm Rally rewards players for building a team containing multiple Bug-class Jinies.

Instead of providing a fixed bonus, its effect increases according to the number of other Bug-class teammates on the lineup.

For example:

1. One other Bug-class Jini: Gains 10% Attack, Defense and Speed.
2. Two other Bug-class Jinies: Gains 20% Attack, Defense and Speed.
3. Three other Bug-class Jinies: Gains 30% Attack, Defense and Speed.
4. Four other Bug-class Jinies: Gains 40% Attack, Defense and Speed.

The bonus applies to both physical and magical offensive and defensive stats, as well as Speed. It does not directly increase HP.

Swarm Rally activates when the Jini enters the battlefield, making team composition especially important before sending Bumbora into battle.

The effect also works with dual-class Jinies, provided Bug is one of their classes.

For example, Bug / Wing teammates can contribute to Swarm Rally just like pure Bug-class Jinies.

However, the trait strengthens the Jini entering the field rather than automatically boosting every teammate. Players should not confuse this with a team-wide permanent stat increase.

Because Bumbora has relatively low attacking and defensive stats, Swarm Rally can help compensate for some of its weaknesses, although the bonus depends heavily on how many Bug-class allies are available.

Stats at every stage

Here is how Species Aptitude grows throughout the evolution line:

1. Buzzlings, 228 total: HP 87, Physical Attack 32, Magic Attack 29, Physical Defense 27, Magic Defense 27, Speed 26
2. Bumbelle, 305 total: HP 116, Physical Attack 43, Magic Attack 39, Physical Defense 36, Magic Defense 36, Speed 35
3. Bumbora, 382 total: HP 145, Physical Attack 54, Magic Attack 49, Physical Defense 45, Magic Defense 45, Speed 44

Buzzlings' total Species Aptitude increases from 228 to 305 after evolving into Bumbelle, then reaches 382 in its final form. That represents an overall improvement of 154 points.

HP is by far the strongest stat throughout the evolution line, increasing from 87 in Buzzlings to 145 in Bumbora.

However, Bumbora's other stats remain considerably lower.

Physical Attack reaches only 54, while Magic Attack is even lower at 49. This makes it difficult for Bumbora to compete with dedicated attackers through raw damage alone.

Physical Defense and Magic Defense both reach 45, leaving Bumbora vulnerable to powerful attacks despite its relatively high HP.

Speed is another major limitation, reaching just 44 in the final evolution.

Swarm Rally helps address some of these shortcomings by increasing multiple stats upon entry, but even with the bonus, Bumbora is better suited to coordinated team strategies than straightforward offensive battles.

Its greatest value comes from supporting Bug-class teammates, applying useful effects and taking advantage of skills that become stronger through team cooperation.

Size and capture details:

1. Buzzlings: 0.37 to 0.52 m, 4 to 5.5 kg. Gives 16 Starlight and a 1,200 Roco Coin base review reward.
2. Bumbelle: 0.81 to 1.16 m, 31.7 to 39.21 kg. Gives 28 Starlight and a 2,100 Roco Coin base review reward.
3. Bumbora: 0.83 to 1.19 m, 61.5 to 78.4 kg. Gives 40 Starlight and a 3,000 Roco Coin base review reward.

Class effectiveness

Buzzlings, Bumbelle and Bumbora all belong to the Bug and Wing classes, meaning their offensive and defensive matchups remain unchanged throughout evolution.

Buzzlings, Bumbelle and Bumbora (Bug / Wing)

When attacking with Bug skills:

1. Deals ×2 damage to: Flora, Havoc and Stellar
2. Deals ×0.5 damage to: Fire, Poison, Fighting, Wing, Charm, Shadow and Mech

When attacking with Wing skills:

1. Deals ×2 damage to: Flora, Bug and Fighting
2. Deals ×0.5 damage to: Earth, Dragon, Electro and Mech

When defending as Bug / Wing:

1. Takes ×2 damage from: Fire, Ice, Electro and Wing
2. Takes ×0.5 damage from: Bug
3. Takes ×0.25 damage from: Flora and Fighting

Unlisted matchups deal normal ×1 damage.

The Bug / Wing combination provides useful offensive coverage, especially against Flora-class opponents.

Both Bug and Wing skills deal double damage to Flora, while Flora attacks deal only a quarter of their normal damage to Bumbora.

This makes Flora one of the most favorable class matchups for the entire evolution line.

Fighting opponents are another interesting target. Wing skills deal double damage to Fighting, while Bug / Wing Jinies take only 25% damage from Fighting attacks.

However, Bumbora has four important defensive weaknesses.

Fire, Ice, Electro and Wing attacks all deal double damage, making these classes particularly dangerous given its low defensive stats.

Electro is especially troublesome because it deals double damage to Bumbora while resisting its Wing attacks.

Wing-class opponents are also unfavorable because they resist Bug attacks and deal double damage in return.

Mech is another class to watch offensively, as it resists both Bug and Wing attacks.

Although Bumbora's high HP provides some staying power, players should avoid leaving it exposed against opponents that can exploit these weaknesses.

Skills and battle strategy

Bumbora has several skills that complement its team-focused playstyle, particularly those involving Offering, Combo Count and support effects.

Some notable skills include:

1. Web Trap: A Bug-class magic attack with 30 Power and no Energy Cost. It deals magic damage and restores 1 Energy.
2. Cocoon: A Bug-class Status skill costing 1 Energy. It restores 20% Health and grants the allied lineup an Offering that provides 10% Lifesteal.
3. Insect Hum: A Bug-class magic attack with 15 Power and an Energy Cost of 2. Its Combo Count increases by 1 for every Insect Hum equipped by Jinies on the lineup.
4. Bind: A Bug-class Status skill costing 2 Energy. It inflicts 2 Poison stacks and grants an Offering that applies another 2 Poison stacks.
5. Swarm Parade: A Bug-class physical attack with 30 Power and an Energy Cost of 3. It performs a two-hit combo and grants an Offering that increases Combo Count by 1.
6. Wingblade: A Bug-class physical attack with 85 Power and an Energy Cost of 3. It removes all Marks from the enemy, or steals them when successfully countering a Status skill.

These abilities allow Bumbora to support different team compositions.

Web Trap provides an efficient way to recover Energy, while Cocoon offers Health recovery and a team-oriented Lifesteal effect.

Insect Hum is particularly interesting because its effectiveness depends on the skills equipped across the entire lineup. When several teammates carry Insect Hum, its Combo Count increases accordingly.

This makes it a natural option for teams built around multiple Bug-class Jinies.

Swarm Parade supports a similar strategy through Offering, allowing the team to benefit from additional Combo Count.

Bind offers a different approach by applying Poison and providing an additional Poison-related Offering.

Bumbora also has several Wing-class skills that help compensate for its low Speed.

Wind Strider is a Wing-class Status skill with an Energy Cost of 2 that increases Speed by 120.

This is particularly useful for Bumbora because its base Speed is only 44.

Gust is a Wing-class physical attack with 75 Power and an Energy Cost of 3. Its Power increases by 50% when the user attacks first.

Combining Wind Strider with Gust creates a more offensive approach, allowing Bumbora to take advantage of increased Speed while strengthening attacks that benefit from moving first.

Plume Rush provides another option, increasing the Power of all skills by 20 and granting Agility.

For a support-focused strategy, players can prioritize Web Trap, Cocoon, Insect Hum and Bind.

For a more offensive approach, Swarm Parade, Wind Strider, Gust and Wingblade provide useful alternatives.

However, Bumbora's relatively low offensive stats mean that even strengthened attacks may struggle against dedicated defensive Jinies. Its effectiveness depends heavily on the rest of the lineup.

Specialties

All three stages share the same Specialty odds:

1. None: 64%
2. Ambusher: 5.8%
3. Affectionate: 5.8%
4. Nimble: 5.8%
5. Fleetfoot: 5.8%
6. Shared Ride: 5.8%
7. Fearless: 5.8%
8. Sharer: 0.48%
9. Homebody: 0.48%
10. Helper: 0.48%
11. Merciful: 0.01%

Most Jinies in this evolution line have no Specialty, with a 64% probability.

Shared Ride is particularly useful for exploration, allowing another Roco to ride alongside the owner.

Ambusher supports wild Jini capture by guaranteeing a Backstab when the Jini is thrown, including against highly vigilant Nightmare-Corrupted Jinies.

Nimble increases gathering range, making it useful for resource collection.

Fleetfoot provides additional movement speed while mounted, offering another exploration benefit.

Helper is a rarer Specialty that can improve EXP gains for teammates after winning battles or capturing wild Jinies.

Merciful is the rarest possibility at just 0.01%, allowing the Jini to leave wild opponents with 1 HP instead of defeating them with a lethal attack.

Where to start

1. Evolve Buzzlings into Bumbora. Buzzlings evolves into Bumbelle at Level 21, then into Bumbora at Level 38. Total Species Aptitude increases from 228 to 382, with HP reaching 145.
2. Build around Swarm Rally. Each other Bug-class Jini on the lineup provides an additional 10% Attack, Defense and Speed when Bumbora enters battle. More Bug-class teammates mean a stronger entry bonus.
3. Prioritize team-based skills. Insect Hum, Cocoon and Swarm Parade can support strategies involving multiple Bug-class Jinies. Bumbora is more useful as part of a coordinated team than as an independent attacker.
4. Take advantage of Flora and Fighting matchups. Bumbora takes only 25% damage from Flora and Fighting attacks. Bug and Wing skills also provide super-effective coverage against these classes.
5. Avoid Fire, Ice, Electro and Wing attackers. These classes deal double damage to Bumbora. Its low defensive stats and Speed make careful switching essential, especially when Swarm Rally cannot provide a substantial bonus.
