Excalibur’s fourth ability is called Exalted Blade. Excalibur summons his ethereal sword and uses it as a melee weapon. The exalted blade behaves like a normal melee weapon. You can use normal attacks, wall attacks and slam attacks with each attack increasing the melee combo counter. You can also perform slide attacks. These will perform a smaller radial blind at the end of the slide attack, at the cost of some energy.
While Exalted Blade is active you have access to a unique melee stance, with its own combo attacks. Attacks with the ethereal blade will create an energy wave in the direction you're aiming with the same damage as the attack that created it. These waves will go through enemies and will eventually dissipate, dealing less damage the more they travel. While Exalted Blade is active, Slash Dash will also produce these energy waves after each hit. While Exalted Blade is active, Excalibur will auto block frontal attacks. If using melee channeling, the auto block can parry enemy melee attacks.
