What Grom's kit does, and what owners spend their coins on first.

What owners bought and how it has gone for them.How to read this

What owners bought is popularity — the game's API reports what a player has unlocked, never what they took into a match. How it has gone is the win rate among the players who made each choice, which covers the ability and the kind of player who picks it together. Neither is a recommendation from us: BrawlZone does not rank Grom's kit, and nothing here is an opinion about what you should buy.

Read from 3,102 first-buyers
Counted from tracked players who own exactly one of the pair: they chose it, and every battle they played on this brawler was played with it, so this measures a decision rather than ownership. It is not a controlled comparison. Which option a player bought is their own choice, so each win rate covers the ability and the kind of player who picks it together. Owning one option does not make two groups otherwise alike, and nothing here separates the two. Read it as how it has gone for the people who bought each one — not as what the ability will do to your win rate.

GearGears owners buy

Gears cost coins and you can only run two, so what owners have bought is a real preference.

Measured across 23,534 tracked players who own this brawler. “Of owners” is how many of them have that item; “of picks” is its share of every unlock of that kind, which is what makes the options comparable with each other. A player can own several gears, so the first column does not add up to 100% and the second does. Almost all of them own both star powers and both gadgets.
