Quick answer

Use the combat input and timing shown by the game, then confirm the successful deflect state before treating the action as learned. The exact button mapping and the difference between deflect, parry and Issen still need version-specific gameplay confirmation on this guide.

What to do

  1. Set the correct input layout

    Open the control page for your platform and make sure the defensive input is known before practicing timing.

  2. Read the attack cue

    Practice against one repeatable attack and watch for the game animation or response that signals a successful defensive action.

  3. Separate the result

    Record whether the action produced a deflect, a parry, an Issen opportunity or only a normal block.

Evidence notes

The Boomstick Gaming combat transcript is a gameplay-context source. Capcom and Steam establish the game context but do not document every timing window.
