Parry and Riposte

Parry and riposte names a defensive pair: a parry is a short window in which a timed input deflects an incoming attack rather than blocking or dodging it, and the riposte is the critical strike it opens against an attacker left recovering. What a successful parry guarantees in the Souls games is the stagger window, not the hit: the player still has to convert it with a separate positional input. Unlike a block, which trades stamina or Poise for safety, a parry converts the exchange into a net loss for whoever attacked.

The window's size sets the risk-reward directly. A generous window is forgiving but cheap, since it can be thrown out on a guess with little cost for missing; a narrow one demands a genuine read of the enemy's Frame Data and punishes a wrong guess with the parry's own recovery, usually longer and more exposed than the attack it failed to stop. Startup and recovery on the parry itself keep it from being strictly better than blocking, and exact window lengths are typically established the way Poise breakpoints are, through community Datamining rather than a published number.

A deflect variant, most legible in Sekiro's posture system, inverts the incentive: instead of a narrow window that rewards patience, timed deflects can be attempted on most attacks, and stacking them successfully builds stagger faster than waiting ever could. The exception is the design's central device: perilous attacks, flagged on screen, cannot be guarded at all and must be answered with a jump, a sidestep or a Mikiri Counter — one input the deflect rhythm cannot absorb. Everything else rewards constant aggression over the cautious spacing that a dodge roll's Invincibility Frames otherwise encourages.

Parries are the clearest expression of a game's read-and-react contract because they collapse offense and defense into a single instant: success requires reading the enemy's Game AI-driven tell correctly and reacting inside a window that Determinism guarantees will be the same length every time. That reliability is what lets skilled play look inevitable rather than lucky, and once a community has measured a boss's parriable frames precisely enough to publish them, that number becomes as central to the Metagame as any Tier List ranking.
