Sirius is not a basic damage dealer. He is a Controller who collects copies of enemy Brawlers and summons them as Shadows. His strength comes from building an army, controlling key areas, and forcing opponents to fight several targets at once.
Based on build data updated on July 18, 2026, The Darkest Starr is the clear favorite Star Power, while A Starr Is Born is the most popular Gadget. Shield and Damage are also almost tied as his two most-used Gears.
Sirius Best Build at a Glance
| Build Slot | Best Choice | Why It Works |
|---|---|---|
| Gadget | A Starr Is Born | Creates an extra Shadow and slows the enemy hit. |
| Star Power | The Darkest Starr | Speeds up Shadow collection and prepares a stronger Super. |
| Gear 1 | Shield | Adds 900 temporary Health for safer opening fights. |
| Gear 2 | Damage | Grants 15% more damage while below 50% Health. |
| Alternative Gear | Health | Improves recovery between fights. |
| Best Overall Mode | Solo Showdown | Has the highest win rate in the supplied mode data. |
| Strong Ranked Modes | Brawl Ball, Hot Zone, Gem Grab, and Knockout | Shadows provide strong lane and objective pressure. |
Who Is Sirius and What Is His Playstyle?
Sirius is a Controller Brawler built around collecting and commanding enemy Shadows. Instead of relying only on direct damage, he creates a numbers advantage by summoning copies of the enemies he attacks.
His main attack, Binary Starr, uses two different projectiles. Ticket Bomb deals area damage, while Shadow Strike hits one target and contributes toward collecting a Brawler Shadow.
After landing enough Shadow Strikes, Sirius can store a copy of the enemy Brawler. He can hold up to three stored Shadows before releasing them with his Super, Shadow Summon.
These copies can pressure enemies, guard an area, block attacks, or help control an objective. This makes Sirius a setup-heavy character. He becomes much stronger when he has time to land attacks, collect valuable Shadows, and choose the right moment to summon them.
Players who use the Super too early may lose most of its value. In many situations, it is better to wait until several Shadows are ready before starting an important fight.
What Is the Best Sirius Build?
The best general-purpose Sirius build is A Starr Is Born, The Darkest Starr, Shield Gear, and Damage Gear.
This combination supports every major part of his kit. The Gadget gives him an immediate summon and crowd-control effect. The Star Power speeds up his normal Shadow collection. Shield gives him more room to survive the first enemy push, while Damage helps him finish close fights.
| Ability or Gear | Pick Rate |
|---|---|
| The Darkest Starr | 84% |
| Dusk Runners | 16% |
| A Starr Is Born | 71% |
| Master of Shadows | 29% |
| Shield Gear | 38% |
| Damage Gear | 37% |
| Health Gear | 9% |
| Gadget Cooldown Gear | 8% |
| Vision Gear | 4% |
| Speed Gear | 4% |
The close pick rates of Shield and Damage do not mean that players must choose between them. They work well together and form the safest default Gear combination for most maps and modes.
Which Gadget Is Best for Sirius?
A Starr Is Born
A Starr Is Born is the best Sirius Gadget for most game modes. Sirius fires a special projectile that summons a Shadow when it hits an enemy. The target is also slowed by 20% for 2 seconds.
The Gadget is powerful because it skips part of his normal setup. Instead of waiting to collect another Shadow through repeated attacks, he can immediately add another unit to the fight.
The slowing effect also makes it easier for Sirius, his teammates, or the new Shadow to continue attacking the target. It is especially useful when an enemy is escaping, carrying Gems, pushing the Brawl Ball, or contesting an important objective.
Some older build pages list a 17-second cooldown, but its current cooldown is 20 seconds. Despite the longer cooldown, it remains the most popular Gadget because of its immediate and reliable value.
Master of Shadows
Master of Shadows recalls summoned Shadows and restores part of their Health. It can be useful when Sirius has already collected several valuable copies and wants to keep them alive.
However, this Gadget depends on having active Shadows worth saving. A Starr Is Born is easier to use and provides faster value during short or chaotic fights.
Master of Shadows is mainly worth considering when your strategy focuses on protecting an existing Shadow army rather than generating immediate pressure.
Which Star Power Is Best for Sirius?
The Darkest Starr
The Darkest Starr is the best Star Power for Sirius. Normally, landing enough Shadow Strikes allows him to store one copy of the enemy Brawler. With The Darkest Starr equipped, the collection trigger stores two Shadows instead of one.
This greatly improves his setup speed. A single successful collection cycle can prepare most of his Super, which means he spends less time attacking before he can start a major push.
Its 84% pick rate shows how important faster Shadow generation is to his strongest build.
Dusk Runners
Dusk Runners increases the movement speed of summoned Shadows by 15%. The extra speed can help slower copies stay close to enemies or reach a guarded area sooner.
It may feel useful on open maps where opponents have more space to escape. However, faster Shadows do not help if Sirius cannot collect enough copies in the first place.
The Darkest Starr improves the core engine of his kit, while Dusk Runners only improves Shadows after they have already been summoned. For most players, faster collection is more valuable.
Which Gears Should You Use for Sirius?
Shield Gear
Shield is the most popular Sirius Gear, with a 38% pick rate. It grants an extra 900 Health as a consumable shield. The shield regenerates in 10 seconds after he returns to full Health.
This Gear helps cover one of his biggest weaknesses. Sirius needs time to build his Shadow army, so the extra protection can stop an assassin or burst Brawler from defeating him before his setup is ready.
Shield is especially useful in Solo Showdown, Knockout, and other modes where surviving the opening exchange can decide the entire round.
Damage Gear
Damage is the second-most popular Gear, with a 37% pick rate. It increases his damage by 15% while he is below 50% Health.
This bonus is strong during close fights. Enemies may struggle to finish Sirius while they are also dealing with his Shadows, giving him time to use the extra damage and secure a takedown.
Health Gear
Health is the best defensive alternative. It increases natural healing by 50%, allowing him to recover faster after taking damage.
Use Health instead of Damage when the map gives Sirius regular chances to retreat, heal, and restart the fight. It can also work well in slower modes where preserving the Shadow army matters more than burst damage.
Gadget Cooldown Gear
Gadget Cooldown has an 8% pick rate. It is not part of the standard build, but it can help compensate for the longer cooldown of A Starr Is Born.
This Gear may be useful when your strategy heavily depends on creating extra Shadows through the Gadget. However, replacing Shield or Damage usually makes the overall build less balanced.
What Are Sirius's Best Game Modes?
Solo Showdown
Solo Showdown is Sirius's strongest overall mode in the supplied data. He has a 68.38% win rate, a 38.40% use rate, and the highest play rate among the listed modes.
The mode suits him because his Shadows provide extra bodies without requiring real teammates. He can use them to scout bushes, pressure enemies, block projectiles, or overwhelm isolated Brawlers.
One community strategy recommends storing several Shadows before releasing them together. This can create a very strong late-game push, although waiting too long may leave him vulnerable during the early stages of the match.
Ranked and Team Modes
Sirius also performs well in several Ranked modes where lane control and objective pressure are important.
| Game Mode | Win Rate | Use Rate |
|---|---|---|
| Brawl Ball | 58.66% | 4.71% |
| Gem Grab | 57.66% | 3.04% |
| Hot Zone | 56.86% | 11.77% |
| Knockout | 56.69% | 5.47% |
| Heist | 55.79% | 3.92% |
Brawl Ball is a strong option because the slow from A Starr Is Born can interrupt an enemy push or prevent a ball carrier from escaping.
Hot Zone also fits his design because several Shadows can enter the area, distract opponents, and make it harder for the enemy team to maintain control.
Gem Grab rewards his ability to protect a lane and chase a low-Health Gem carrier. In Knockout, he can build a powerful numbers advantage if he survives long enough to summon multiple copies.
However, staying alive is essential. When Sirius is defeated, his active Shadows are also removed, which can instantly end his team's pressure.
How Should You Play Sirius?
Sirius is strongest when the player treats Shadows as a limited resource instead of releasing them without a plan. His basic gameplay loop focuses on landing Shadow Strikes, building a useful collection, and summoning the copies during an important fight.
- Use Ticket Bomb to pressure grouped enemies and control narrow areas.
- Aim Shadow Strike carefully because successful hits build your main resource.
- Avoid using the Super with only one weak Shadow unless the situation is urgent.
- Use A Starr Is Born when the slow can secure a takedown or protect an objective.
- Summon several Shadows before a major team fight to create a numbers advantage.
- Send the copies toward an important lane or objective instead of letting them move without purpose.
- Use Shield Gear to survive the first burst and Damage Gear to fight back below 50% Health.
Do not stand directly on top of your summoned units. Spreading out forces enemies to choose between attacking Sirius and clearing the Shadows. It also prevents area attacks from damaging every target at once.
You should also pay attention to which enemy Brawlers are being copied. A useful Shadow can change the entire fight, while a weak copy summoned in a poor position may provide very little pressure.
Is Sirius Worth Upgrading?
Yes, Sirius is worth upgrading for players who enjoy control-focused Brawlers, summon mechanics, and tactical positioning.
He offers something that few Brawlers can match: the ability to build a temporary team from enemy copies. This gives him excellent snowball potential and allows skilled players to pressure several parts of the map at once.
His biggest strengths are strong Shadow-based map pressure, excellent Solo Showdown performance, useful slowing tools, flexible Super commands, and a high skill ceiling.
However, he also has clear weaknesses. Sirius needs repeated hits before reaching full power, and the longer cooldown of A Starr Is Born makes poor Gadget usage more punishing. He can also lose his entire Shadow army when defeated.
Players who prefer instant burst damage may find his setup too slow. Those who enjoy Controllers and strategic resource management should get much more value from investing in him.
