The most likely way to change dojo in Dueling Grounds is through the game’s map selection or rotating shop system, where dojo appears as one of the purchasable maps rather than a permanent menu setting. The update note specifically says Dojo and Volcano can be bought with Coins, while Ruins and Underworld use Gems, and that map selection was added to matchmade games.

How to do it

  1. Open the game’s map selection or rotating shop area in Dueling Grounds.
  1. Look for Dojo in the available maps.
  1. Buy it with the required currency if it’s currently in rotation.
  1. Queue into a matchmade game and use the selected map if the mode supports it.

What matters

  • If you do not see Dojo, it may not be in the current rotation yet.
  • The game’s Roblox page also shows that controls and settings can vary by platform, but it does not show a separate dojo-change setting.
  • Community guides generally focus on combat, weapons, and map selection rather than a dedicated dojo toggle.

Quick note

If by “dojo” you mean the map , the answer is: select or buy it when it appears in rotation. If you meant a different in-game feature, that part is not clearly documented in the sources I found.

TL;DR: In Dueling Grounds, dojo is handled like a map selection item, not a simple settings switch, and you usually change it by buying/selecting it in the rotating map system.
