About this map

Undermine runs in Gem Grab. The numbers below come from 689,310 battles, with 107 brawlers showing up in the data. Trunk tops the win rate here at 70.1%, with Bolt in second at 66.7%. Edgar is the most common pick at a 4.8% use rate, winning 56.5% of its games. Gem Grab maps are defined by how contested the center mine is. A tight center favors burst damage and area denial, a spread-out one rewards flanking.

Trunk stands out here, winning 18.7 percentage points more than the average brawler tracked on this map. The most-used pick here isn't the strongest one, Trunk still edges it out. Bonnie is one to avoid, sitting at just 30.4% on this map. Undermine isn't in the current rotation right now; the numbers above are from its last time live.

Which brawler is picked most on Undermine?

Edgar is the most-used brawler on Undermine, appearing in 4.8% of tracked games with a 56.5% win rate. Popularity and win rate don't always line up, so it's worth checking the full rankings table before assuming the most common pick is the best one.

Which brawlers should you avoid on Undermine?

Bonnie, Grom and Jacky have the weakest combination of win rate and use rate on Undermine, with Bonnie sitting at 30.4%. These aren't unplayable, but they're fighting the map's layout rather than working with it.

Which comps win most on Undermine?

Amber, Griff and Gus is the strongest recorded comp on Undermine, winning 71.8% across 110 games together. A strong solo pick doesn't always mean it fits into the best team shape, so drafting around a known comp can beat drafting three good individual picks that don't synergize.
