Roblox Steal a Brainrot: 10 Must-Buy Shop Weapons to Dominate Every Round

If you are trying to keep your precious Brainrots safe in Roblox's Steal a Brainrot (or you just enjoy causing a little chaos), the shop is a minefield. Some gadgets are priceless. Some are shiny trash. Here are the ones actually worth your cash and Rebirths, plus a few gotchas the game does not spell out.

The loadout that actually works

1. Giant Potion — Turn into a walking anti-theft system. You blow up to roughly 4x normal size, swing comically oversized versions of your other gear, jump higher, and you cannot be ragdolled for 20 seconds. When it wears off, you pop back to normal. If you like ending chases, this is the button to press.
   Cost: $1.5 billion. Rebirths: 17 required.
2. Attack Doge — A very fast, very rude pupper spawns at your side for 11 seconds, locks onto nearby players, and drops anyone who touches it straight into ragdoll. People can destroy the dog with the right tools, but if you time it right, you get a clean window to recover your Brainrots.
   Cost: $1 billion. Rebirths: 16 required.
3. Laser Gun — Premium toy, big knockback. Fires a beam that can ricochet off objects (up to three bounces) before fizzling. Anyone tagged gets launched and stuck with a dark screen tint for 3 seconds. It is great for blasting thieves off angles or into the open.
   Cost: 749 Robux. Rebirths: none required.
4. Quantum Cloner — Place an NPC decoy anywhere and swap positions with it on command. The nasty trick: park your clone inside a locked base, hit the swap, and you are suddenly past the door like it was never there. Fantastic for heists or quick escapes.
   Cost: $3.5 million. Rebirths: 7 required.
5. Medusa's Head — Look at a thief, turn them to stone for 3 seconds, then they slump into ragdoll. While petrified and during the follow-up ragdoll, they cannot use tools to bail out. Walk over, take your stuff back, move on with your day.
   Cost: $5 million. Rebirths: 5 required.
6. Invisibility Cloak — Pure stealth with a big speed boost and, yes, no cooldown. You are invisible, you are fast, and you can do it again immediately. If a rare Brainrot catches your eye, this is how you snatch it without turning it into a brawl.
   Cost: $400,000. Rebirths: 4 required.
7. Rage Table — You literally hurl a table at people. Anyone you tag goes limp in ragdoll for a moment, which is usually long enough to interrupt a getaway or clean up a multi-target mess when a group is clustered.
   Cost: $25,000. Rebirths: 2 required.
8. Web Slinger — Fire a line, snare someone for 10 seconds, and reel them toward you. The mean detail: webbed players cannot use other tools to break free. Great for isolating a runner or yoinking a troll off a rooftop.
   Cost: $2 million. Rebirths: 6 required.
9. Bee Launcher — Weaponized nuisance. Tag someone and their controls invert while their screen turns a sickly yellow for 5 seconds. It is the perfect stumble-maker when a thief is inches from safety.
   Cost: $10,000. Rebirths: 1 required.
10. Trap — Cheap and sneaky. Plant up to five at once; anyone who steps on one is stuck for 7 seconds. Caution: trapped players can break out using certain tools, so layering traps or pairing them with a hard disable (Web/Medusa/Doge) is how you lock things down.
    Cost: $1,000. Rebirths: none required.

What to know before you spend

Big-ticket items are gated behind Rebirths, so do not expect to stroll into giant mode on day one. The Laser Gun is the outlier: it costs Robux and ignores the Rebirth wall entirely. Also, a few oddities worth flagging: the Invisibility Cloak really has no cooldown, the Laser beam dies after three ricochets, and Web Slinger victims cannot wriggle free with tools, while basic Trap victims sometimes can. Use those quirks to your advantage.
