Break Issen Body-Part Targeting
Regular Break Issen executes an enemy after their stamina is broken. A special extended form of the mechanic activates when Musashi wears a foe out completely: he can freely choose a body part to attack, such as a head or specific limbs.
Why It Exists
Targeting-specific finishers are a staple of samurai-film swordplay, and they also give the player an in-fight reward for committing to the harder path of fully exhausting an enemy rather than burst-killing them. The choice of body part doubles as a tone hit and as a tactical option in group fights.
Relationship to Standard Break Issen
Standard Break Issen is triggered immediately after an enemy's stamina breaks, usually as a single clean execution. The body-part variant sits one step beyond that, needing the player to sustain pressure longer before it unlocks.
