The User Interface (UI) provides vital information during missions. In the top-left corner, you'll find your character's health bar, special attack gauge, and Sheikah Slate Rune cooldowns. The top-right displays the mission timer and current objective. The mini-map, usually in the bottom-left, shows enemy locations, outposts, and objective markers. Pay close attention to the mini-map to track enemy movements and plan your routes.
When targeting a powerful enemy, their Weak-Point Gauge will appear. Depleting this gauge allows you to unleash a devastating Weak-Point Smash. Keep an eye on character portraits at the bottom of the screen; these indicate which characters are currently deployed and their health. Understanding the UI will help you make informed decisions in the heat of battle and manage your resources effectively.
