In this game, jumping from high above to a level or ground below will stun you for a split second, sometimes leaving you vulnerable to enemy attacks and other threats. To avoid this from ever happening, simply press the X button to attack right before you land. This will allow Tenchu to attack in a downward slash, negating the otherwise-ill effects from a high fall.

When falling from a high place, you can do the tumble, but it will leave you temporarily vulnerable to enemy attacks. To prevent such an occurrence, hold down the stealth button (R1) while falling, holding the button until you land. If you do this properly, you'll land crouched instead of tumbling, making you instantly ready to deal with any enemy threat.
