--- title: Legend of Defenders Settings: Windowed, Auto Battle, Keys description: Legend of Defenders settings and controls: auto battle, target modes, windowed and borderless display, effects, Boss Key, swapping heroes, formations and bulk levelling. url: https://legendofdefenders.com/game/settings-and-controls/ --- Game info · **settings** # Legend of Defenders settings and controls Legend of Defenders plays with the mouse alone. Turn on **auto battle** and heroes cast skills and the cannon fires by itself; in Settings, keep "auto next wave" on for idling.[Nerfed Reflexes 10:28](https://www.youtube.com/watch?v=etJMFiRxGYo&t=628s) There is no windowed fullscreen yet. Quick answer - Boss Key hides the window and its taskbar icon. - Swap heroes with the button under the character panel. - Font size can't be changed yet. - Placement barely matters; lineups do. ## How does auto battle work in Legend of Defenders? - Heroes, turrets and cannons always attack on their own. The **Auto** button also casts hero skills when their MP is ready.[Nerfed Reflexes 8:53](https://www.youtube.com/watch?v=etJMFiRxGYo&t=533s)[AboboKnows 13:31](https://www.youtube.com/watch?v=oSpOuExSDiI&t=811s) - With auto battle on, the main cannon and hero skills aim themselves. Press **Exit Auto** to aim skills and the Siege Bow yourself.[Nerfed Reflexes 8:53](https://www.youtube.com/watch?v=etJMFiRxGYo&t=533s) - **Target Boss** mode: the monster castle counts as a boss too. A player reports the mode only kicks in once the boss is close; the developer is checking it. - The "Total DPS" meter shows total damage, not damage per second; a true DPS meter costs too much CPU for now. ## What is in the Settings menu? Settings sit in the bottom-right corner. Options seen on launch day: - **Auto next wave**: keeps waves going while you are away.[Nerfed Reflexes 10:28](https://www.youtube.com/watch?v=etJMFiRxGYo&t=628s) - **Auto battle fail rewind**: steps back after a loss instead of stalling. This is the only way back to an earlier wave; there is no wave select.[Nerfed Reflexes 10:28](https://www.youtube.com/watch?v=etJMFiRxGYo&t=628s) - **Hide damage numbers**.[Nerfed Reflexes 10:28](https://www.youtube.com/watch?v=etJMFiRxGYo&t=628s) - **Resolution**, with more sizes promised. - **Boss Key**: one key hides the game, taskbar icon included. ## Windowed, borderless and effects: what works? - **Windowed fullscreen** (a window at your screen size) is not in the game; the developer says maybe next version. - **Borderless** currently leaves the taskbar visible over the game; the developer said they will fix it. - **Font size** can't be changed yet, which makes skill text small at 2K; an option may come later. - **Combat effects**: the full game has an effects setting, but some skills are bound to their effects and stay visible. Players sensitive to flashing should know this before buying. ## How do I swap, level and star up heroes faster? - **Swap positions:** use the button at the bottom of the character panel instead of removing and redeploying. Position barely changes range or damage; the developers built it so you swap lineups, not tiles. - **Formations** keep the gear each hero wore; unequip and re-equip and the formation follows. - **Level in bulk:** hover the level-up button without clicking, then pick an amount from the list (up to 1,000 levels). - **Star up everything at once** is in development. - **Upgrading during waves** is in development; for now most management happens between battles. - The tutorial can't be skipped; it takes about five minutes. ## Legend of Defenders settings questions ### Does auto battle cast skills and fire the cannon in Legend of Defenders? Yes. With auto battle on, heroes cast their skills and the main cannon fires on its own. Press Exit Auto to aim skills and the Siege Bow yourself. ### Is there a windowed fullscreen mode? Not yet. The developer is considering it for a later version. Borderless mode currently leaves the taskbar visible, which the developer has said they will fix. ### Can I turn off flashing combat effects? Partly. The full game has an effects setting, but some skills are tied to their effects, so those stay on. ### How do I swap two heroes? Use the button at the bottom of the character panel to move heroes between slots instead of removing and redeploying them. ### Can I skip the tutorial? No. It takes about five minutes; the developer may add a skip option later.
