Rotboxes are the only way to catch Brainrots. You buy them at the Rot Center Shop NPC in each zone hub, throw after battle, and climb from cheap early boxes into tougher Ice gear as targets outgrow the last one you stocked.

Grass Zone
These are the early shop boxes for Grass hub grinding. Unlock order is Rot, then Silver at Level 3, then Gold at Level 6. Match the box to the target's level band so you are not paying Gold prices on easy catches.

Buy Rotboxes at the Rot Center in the zone hub. Open the building, talk to the Shop NPC on the right side, and grab what your level unlocks. You can mini-map teleport to the hub if you are out in the field with empty pockets.
Stronger boxes get rejected less often. That still is not a free catch on normal shop stock. Soften the Brainrot in battle first with Energy and Charge abilities, then throw. Weak targets waste fewer boxes, and that matters once Coin prices jump in Ice.
Grass into Ice
Start on the Rot Box while early Grass targets sit at low levels. At Level 3, Silver covers mid Grass. At Level 6, Gold handles the late Grass band up through about Level 22. Do not burn Gold on the weakest spawns when a cheaper box still works.
Ice starts at Level 9 with the Snowbox, and it is Coins only, so keep a Coin cushion before you cross over. Snowman, Miner, and Frozen unlock at Levels 13, 17, and 20. Each step is for a harder Ice stage, not a reason to dump your whole wallet on day one.
When to spend Robux
Most boxes sell for Coins or Robux. Snowbox is Coins only. Exclusive Infinity Box is Robux only at 380 each, has no level gate, and always catches, even at full health. Save Infinity for the target you refuse to risk losing. For everyday farming, climb the Coin track and upgrade when throws start bouncing.
If a throw fails, you still spent the box. Stock a few of the right tier, finish the fight cleanly, then throw. Chasing rare Ice targets with under-leveled stock is the fastest way to empty the bag.
FAQ
Where do you buy Rotboxes?
At the Rot Center Shop NPC in each zone hub. Go inside the building and use the shop on the right side. Mini-map teleport can drop you at the hub when you need a restock.
Do stronger Rotboxes always catch?
No. Stronger shop boxes raise your odds and cut rejections, but only Exclusive Infinity Box is a guaranteed catch. For everything else, weaken the Brainrot first.
What is special about the Exclusive Infinity Box?
It costs 380 Robux each, has no unlock level, and always catches any Brainrot, even at full health. It is the premium guarantee, not the everyday farming box.
Why is Snowbox Coins only?
The shop sells Snowbox for Coins only. Plan Coin savings before Ice if you want that first cold-region box without spending Robux on later tiers instead.
Should you throw before the fight ends?
Weaken the Brainrot in battle first, then throw. Healthy targets reject boxes more often and burn stock you paid for.
