The universal 'get out of danger' button that turns your character into an invincible tumbling ball.
Dodge rolling is the act of performing a quick evasive roll, typically granting i-frames during the animation. It's become the default defensive mechanic in third-person action games, to the point where 'has dodge rolling' is practically a genre checkbox. The design variables are distance traveled, recovery time, i-frame count, directional control, and stamina cost. Some games let you spam rolls endlessly; others force you to commit to each one. The best implementations make dodging feel like a skill rather than a panic button -- timing and direction matter more than just mashing the button.
Example
Dark Souls defined the modern dodge roll -- weight-dependent, stamina-costing, and requiring precise timing to exploit i-frames. Bayonetta's Witch Time takes it further, rewarding perfect dodges with slow-motion that lets you punish enemies. Monster Hunter's dodge is deliberately heavy and committal, with different weapon types having different dodge animations and i-frame windows.
Why it matters
Dodge rolling is so ubiquitous in action games that its absence is notable. It's the primary way players interact with enemy attacks, and its feel defines the entire combat rhythm. For devs, the dodge roll is deceptively simple to implement but incredibly difficult to tune until it feels just right.
