Onimusha: Way of the Sword Issen Guide
Issen is Onimusha's signature critical counter. In Way of the Sword, the core timing is to attack at the last moment, just before an enemy strike connects, then stay calm enough to chain follow-up Issen hits when the fight allows it.
Quick Answer
To perform Issen, wait until an enemy attack is about to land, then press attack at the last moment. For Chain Issen, keep reading the next incoming attacks after the first successful Issen instead of mashing.

How to Perform Issen
- Watch the enemy's committed swing. Do not react to the first twitch or step forward. Wait until the attack is actually coming in.
- Press attack just before impact. The regular Issen timing is an attack input placed right before the enemy hit lands.
- Reset after a miss. If the input is too early or too late, treat it as a failed counter and move back into a defensive rhythm.
What Issen Is
Issen is a high-risk critical attack built around timing. It is different from holding guard because the counter depends on committing to an attack input at the correct moment.
No reliable source confirms an exact frame window, so this guide does not claim one.
Issen Timing and Counter Timing
- Use the final swing, not the wind-up. Pressing during the wind-up usually turns into a normal attack.
- Look for committed attacks. The best cue is when the enemy can no longer simply reposition.
- Prefer readable melee attacks. Slow, direct swings are better practice targets than chaotic multi-hit pressure.
- Do not treat Issen like a block. If you are unsure, defend first and try again on a cleaner pattern.
Chain Issen and How to Chain Issen
- Start with one clean Issen. A chain starts from a successful counter, not from repeated button presses.
- Watch the next enemy immediately. After the first hit, look for another incoming attack cue instead of staring at the defeated enemy.
- Time each follow-up separately. Chain Issen rewards rhythm, but each follow-up still needs a real attack window.
- Stop when the screen becomes unclear. A short chain is better than losing health by forcing one more hit.
Training and Practice Tips
- Practice on slower melee enemies. Their attack arcs make the hit moment easier to learn.
- Practice one enemy pattern at a time. Learning one clean counter window is more useful than guessing at every move.
- Turn misses into spacing practice. After a failed Issen, dodge or block instead of mashing.
Boss Applications
Issen is useful in boss fights when a move has a clear cue, but it is not the answer to every attack. Against Yoshitsune, checked final-boss guides call out red-glowing claw attacks as useful Issen opportunities when your timing is ready.
Use the Final Boss Guide for the full Yoshitsune plan, and the All Bosses guide for the broader boss route.
Common Mistakes
- Pressing too early. An early attack usually becomes a normal swing instead of an Issen.
- Mashing attack. Repeated inputs make the timing less precise and can leave you exposed.
- Trying to chain every time. Chain Issen is useful, but forcing it in messy fights can cost more health than it saves.
