Brawl Stars Sirius build: Best Gadget, Star Power, and Gears

The best Brawl Stars Sirius build pairs the A Starr Is Born gadget with The Darkest Starr star power, supported by Shield and Damage gears. This setup speeds up shadow generation and strengthens defensive survivability during area control.

Best Sirius Build Loadout

Sirius functions as an Ultra Legendary controller capable of summoning and directing copies of opposing brawlers. His primary attack, Binary Starr, launches a lobbed Starr Bomb that deals area damage and a straight-line Shadow Strike. Each projectile deals 1,200 damage at Power Level 11, totaling 2,400 damage when both land together.

Because Sirius relies on gathering enemy shadows to build presence, your loadout must prioritize rapid shadow accumulation. The standard competitive build features:

• Gadget: A Starr Is Born
• Star Power: The Darkest Starr
• Gear 1: Shield
• Gear 2: Damage
• Hypercharge: Unlimited Power!

This loadout provides immediate pressure against frontline tanks and ensures Sirius can summon shadows quickly during team engagements.

Gadget Breakdown: A Starr Is Born vs. Master of Shadows

A Starr Is Born serves as the primary offensive gadget for Sirius. When activated, Sirius fires a skillshot projectile that generates a shadow of the struck target immediately on impact. The hit enemy also suffers a 20% movement slowdown lasting two seconds. This gives Sirius an instant summon without needing to land multiple basic attacks first. The projectile slow helps confirm follow-up attacks or disrupt aggressors attempting to collapse onto his position.

Master of Shadows focuses on defensive utility and shadow preservation. Activating this gadget recalls all active shadows back to Sirius and heals them for 25% of their health pool. Stored shadows retain 60% of the target brawler's base health and 55% of their damage output. Calling them back protects injured shadows from area-of-effect abilities while clustering multiple bodies around Sirius to absorb oncoming fire.

Star Power Breakdown: The Darkest Starr vs. Dusk Runners

The Darkest Starr stands out as the standard star power selection. Sirius normally gathers one stored shadow on every fourth hit from his basic attack. With The Darkest Starr equipped, each landing hit from Shadow Strike counts as two points toward shadow collection. This mechanic allows Sirius to fill his shadow storage 50% faster, letting him summon three shadows in rapid succession.

Dusk Runners increases the movement speed of all summoned shadows by 15%. This bonus helps melee shadows close distance against mobile targets. Fast tanks such as Bull or Frank benefit from this speed boost when chasing opponents across open ground. Even so, generating shadows rapidly provides more tactical flexibility than moving existing summons faster.

Gear Selection

Shield Gear provides an extra 900 consumable health, raising Sirius from 6,800 base health to 7,700 total effective health. Because Sirius has moderate survivability and needs to step forward to land Shadow Strikes, the initial shield absorbs opening poke from long-range snipers.

Damage Gear grants a 15% damage increase whenever Sirius falls below 50% health. This increases his basic attack output during close-range trades, helping him fend off divers and secure eliminations while injured.

Gadget Cooldown Gear provides an effective alternative on maps with heavy chokepoints. Reducing gadget downtime allows Sirius to apply the slow effect from A Starr Is Born more frequently. Health Gear remains viable on open terrain where players step behind cover to recover health before pushing back into lane.

Decision Table for Sirius Loadouts

Super and Hypercharge Usage

Sirius uses his Super, Shadow Summon, to deploy up to three stored shadows simultaneously, with a match limit of six shadows active at once. Sirius automatically charges his Super over 1.33 seconds through his innate trait. Once shadows are deployed, aiming the Super places a ground waypoint that commands summons to guard that specific radius, while tapping the Super orders them to follow Sirius directly.

Activating the Unlimited Power! hypercharge grants Sirius a 20% speed boost, a 5% damage boost, and a 5% shield. Shadows summoned during this hypercharge gain upgraded combat stats, possessing 85% of their original counterpart's health and 70% of their base damage. Combining three stored summons with hypercharge creates an overwhelming push across best brawlers on the enemy team.

Game Mode Applications

Sirius shows strong performance across objective-centered modes where static ground control decides the match.

Brawl Ball

Brawl Ball allows Sirius to exploit tight pathways and utilize summoned tanks to clear shooting lanes. Because his Super recharges automatically, players can use the Super button to execute long-distance passes and trick shots while summons advance toward the enemy net. Opponents facing multiple high-health summons struggle to defend against coordinated goal rushes.

Hot Zone

Contested capture points force enemies into fixed boundaries, allowing Starr Bomb splash damage to hit multiple targets at once. Stacking shadows inside the zone absorbs incoming skillshots and drives enemy controllers backward. While summons cannot capture percentage directly, their presence forces opposing teams to expend ammo clearing them out.

Gem Grab

Sirius controls side lanes effectively by extracting shadows from opposing gem carriers. Deploying summons toward the center mine restricts enemy access to gem spawns. Reviewing our ranked guide helps align your draft choices when facing counter picks like Penny or Emz, whose piercing damage cuts through clustered summons.

Advancing Sirius through high-tier competitive matches also contributes to account progression, rewarding players who push individual brawler prestige levels with exclusive cosmetics and profile upgrades.
