Combat in Blox Fruits is simple but needs a little explaining. To initiate a fight, press the “1” key on your keyboard to enter the combat stance indicated at the bottom of the screen. Your character raises their arms like a boxer when it’s active. On mobile, tap the combat stance button instead.
With that active, any click or tap will throw a punch, hitting the target directly in front. You’ll also notice a couple of skills you can use on the right side of the screen: Quick Tackle and, after you level up your Mastery to 20 through a few fights, Ground Smash. Just tap their indicated keys to perform the powerful knockback and stunning slam, respectively. On mobile, you’ll need to toggle either one and tap as you do for a punch.
You won’t be able to use the skill again until its bar turns transparent again, so using these at every opportunity will help you maximize your damage output, limit incoming damage, and, if you learn to reach a strong opponent’s animations, let you stop powerful moves in their tracks.
