In Blox Monsters, balls are the items you throw to capture monsters after you weaken them in battle. You start the game with the Natural Ball, and you upgrade to stronger balls by spending Coins at the ball shop. Each ball changes two things, your odds of a successful capture and your chance of pulling a higher-rank monster.
Quick answer: Open the ball shop next to the egg hatcher in the Misty Forest starting area, collect enough Coins, then buy the highest ball you can afford. The Demon Ball (80,000 Coins) is the strongest shop option, while the Shadow Ball comes from the Astral Glove NPC quest instead.
What Catch Chance and Rank Luck do
Every ball carries two stats that decide how useful it is. Catch Chance is a multiplier on your odds of capturing a monster once you throw the ball. A higher multiplier means fewer wasted attempts on tougher targets.
Rank Luck increases the chance that a captured monster lands at a higher rank. The Natural Ball gives a modest boost, and the top-tier balls push that bonus far higher. If you want both reliable captures and better monster ranks, you upgrade your ball.
All Blox Monsters balls, stats, and how to get them
The full lineup runs from the free starter ball up to the Shadow Ball, which sits outside the shop. Coin costs climb steeply, so each upgrade is a meaningful jump in both Catch Chance and Rank Luck.
| Name | Stats | Obtainment |
|---|---|---|
 Natural Ball | Catch Chance: 1x Rank Luck: +25% | Owned from start |
 Storm Ball | Catch Chance: 1.4x Rank Luck: +40% | Ball Shop – 500 Coins |
 Mechanic Ball | Catch Chance: 1.8x Rank Luck: +80% | Ball Shop – 5,000 Coins |
 Enthusiasm Ball | Catch Chance: 2.2x Rank Luck: +120% | Ball Shop – 20,000 Coins |
 Demon Ball | Catch Chance: 3x Rank Luck: +150% | Ball Shop – 80,000 Coins |
 Shadow Ball | Catch Chance: 4x Rank Luck: +180% | Astral Glove NPC Quest |
How to buy balls at the ball shop
The ball shop is in the Misty Forest, which is the starting location. It sits right next to the egg hatcher, so you do not need to travel far to find it.
Which ball to prioritize
Early on, the Storm Ball at 500 Coins is an easy first upgrade over the Natural Ball, raising Catch Chance to 1.4x. As your Coin income grows, the Mechanic Ball and Enthusiasm Ball give large Rank Luck jumps, reaching +80% and +120% respectively.
The Demon Ball is the most powerful purchase in the shop, with 3x Catch Chance and +150% Rank Luck for 80,000 Coins. The Shadow Ball edges past it at 4x and +180%, but it is locked behind the Astral Glove NPC quest rather than a Coin price, so you complete that quest to claim the best ball in the game.
