This trick requires a fully leveled-up Royal Guard style. You must posses the "Dreadnaught" ability. Dreadnaught is performed by holding R1 + Left Analog-stick Away + Circle. This ability encases you in invulnerable armor, based upon how full your Royal gauge is. You can still perform Dreadnaught with an empty Royal gauge and get about five seconds of invulnerability. You will also suffer limited movement during a Dreadnaught. Perform Dreadnaught, and at the precise moment it runs out, switch your melee weapon (R2). If done quickly enough, you will keep the Dreadnaught armor and be able to move normally. Note: You will still be able to fully take damage.
