Sirius Hands-On Guide: How to Unlock and Master the 100th Brawler’s Shadow Mechanics

After surviving the frantic post-maintenance rush when the servers went live, I finally spent the weekend stress-testing Sirius, Brawl Stars’ landmark 100th Brawler. As an Ultra Legendary Controller, Sirius completely warps the current meta with his Shadow Control mechanic.

If you want to command his clone army effectively without throwing your matches, here is my hands-on breakdown of how he plays, how to unlock him, and the exact competitive build I’m running.

The Unlock Grind: What My Testing Revealed About the Three Paths

Supercell wasn’t kidding when they said this event would be a brutal grind for free-to-play layers. After mapping out the math and attempting the challenges, here is the real situation on the ground:

1. The Win With Every Brawler Challenge (The Veteran Path)

My Experience: I tried pushing this route first, but there is a massive roadblock. You must physically own all 99 other Brawlers to complete this.
The Reality: Supercell is not offering trial versions for this quest. If your roster is missing even one character, this path is completely locked out for you.

2. The Sirius Box Challenge (The High-Stakes Path)

I ran the numbers on the ticket-to-win ratio, and it is incredibly unforgiving.

The Math: You need 20 Sirius Boxes. Each box costs 2 wins, and you are capped at exactly 40 event tickets.
My Warning: You can only afford to lose exactly two matches throughout the entire event. If you drop a third game, you will fall short of the 20 boxes and be forced to rely on luck or gems.

3. Random Unlock (The Luck Path)

My Drops: While the drop rate for Sirius himself is a minuscule 0.06% per draw (0.48% per box), according to the official player database at BrawlStarsStats, the boxes themselves are massively buffed. In the 15 boxes I opened, I pulled an impressive haul of alternative rewards, including a Hypercharge and two Star Powers, making the grind rewarding even if you don’t hit the jackpot right away.

Mastering the Kit: How Binary Starr Feels in Live Matches

Playing Sirius feels less like a traditional brawler and more like managing a mini-RTS game in the middle of a standard 3v3 match.

Stacking Your Shadows

His main attack, Binary Starr, fires two distinct projectiles simultaneously: a Ticket Bomb (area control) and a Shadow Strike (single-target line).

The Rhythm: In my matches, I found that you cannot just auto-aim this. You need to consistently land the Shadow Strike. On every 4th successful hit, you steal a “Brawler Shadow.”
Shadow Scaling: I noticed my summoned shadows inherited the exact base HP and attack type of the enemy I stole them from. Pro tip: target high-HP tanks like Frank or El Primo to build a tanky front line for your team. You can store up to 3 shadows at a time.

Micro-Managing the Battlefield (Super: Shadow Summon)

Using his Super completely changes your controls, giving you unique macro-management capabilities:

Waypoint Control: When I held and aimed my Super button while shadows were active, it let me drop a physical waypoint on the map. My shadows immediately marched to that zone and held it like defensive sentries.
The Recall: Tapping the Super button instantly snaps them out of guard mode, causing them to run back and body-guard Sirius.

The Competitive Build: Tested Gadgets & Star Powers

After rotating through every combination in Power League matches, here is the definitive tier list for his add-ons:

Gadget 1 (A Starr is Born): Perfect for aggressive plays. It fires a projectile that instantly spawns a shadow on hit while slowing the enemy. I found this vital for securing early-game map control.
Gadget 2 (Master of Shadows): Crucial for sustain. It recalls your active clones and heals them for a chunk of their maximum health.
Star Power 1 (Dusk Runners): Increases clone movement speed. Great for chasing down agile assassins.
Star Power 2 (The Darkest Starr): Modifies your 4th strike to store two shadows instead of one. This is my default pick, as it lets you rebuild your army twice as fast after a team wipe.

The Advanced Combo: Hypercharge Optimization

Sirius’s Hypercharge (Unlimited Power!) gives any shadow summoned during its duration a massive stat boost to both damage and health.

During my test sessions, I discovered a powerful tactical loop that completely changes team fights:

Pop your Hypercharge.
Aggressively summon your buffed, high-stat shadows to overwhelm the point.
The Trick: Right as the Hypercharge timer is about to expire, activate the Master of Shadows gadget.

Because the gadget recalls and heals them based on their current max health, it keeps your super-buffed Hypercharge clones alive and healthy well after your actual Hypercharge state has ended, successfully securing a second consecutive push.
