Issen Counters & Combat Mechanics
Unlike conventional soulslike games where rolling grants invulnerability frames, Onimusha: Way of the Sword penalizes passive evasion. Victory hinges upon reading enemy weapon trajectories and seizing counter windows:
- 1. Issen: Press Attack the moment before an enemy attack makes contact with Musashi. Officially confirmed; exact timing is not published.
- 2. Chain Issen: Follows a landed Issen - confirmed by CAPCOM. Chain limits are not officially specified.
- 3. Break Issen: Opens when an enemy's stamina is depleted - confirmed by CAPCOM. Execution details are not officially specified.

Confirmed: available after completing the campaign, startable on a new playthrough.

The Confirmed Arsenal & Soul Economy (鬼武者 武器)
Per CAPCOM official descriptions, the following weapons and resources appear in the game:
Two Celestials (Twin Blades): The signature weapon. Hits with the twin blades make enemies release yellow souls, so the armament heals you as it deals damage.
Oni Gauntlet (鬼之笼手): The protagonist's defining tool, absorbing souls from fallen enemies.
Souls: Yellow restores HP · Blue fills Oni Power for Oni Armament abilities · Red is spent on upgrades.
Upgrade costs: Exact soul costs per upgrade are not yet verified; guide tables circulating at launch are unsourced and are not published here.
