Each row is measured against that brawler’s own record on this map, so a map that simply favours a brawler does not make all of its matchups look winning. Only matchups with at least 40 sampled battles appear.
Layout
How the map is built, and what that rewards.
Undermine (originally called Temple Catacombs) is an official map for the Gem Grab event. Undermine had a Brawlidays version named Snowball Fight. Temple Ruins was an identical replica of this map for use in the Bounty event.
This map consists of an open middle section and is bush heavy on the left and right section of the map. Walls separate the middle section from the upper/lower sections of the map. There are not many defensive walls as the walls are more of obstacles than defenses. The map is diagonally symmetrical.
