The heavy blade will slow you down as well as raise your pulse faster than one-handed swords, but the reach is excellent and each blow delivers lots of damage. Two-handed swords are the only two-handed weapons that let you equip shields. In addition to defense, shields can also be used to reflect attacks on the foe with a well-timed block. As you become more proficient, you will also be able to follow a successful deflection with a counter-attack by pressing [cross]. After dodging an enemy's attack, you can press [square] to perform an Evade Strike. Hold down [circle] to charge your magic power and use charge spells. As your magic proficiency increases, the amount of time needed to charge will decrease. As upgrades progress, you could potentially unlock other paths, so be sure to keep options and eyes open for these branching paths.
Rampaging Blade lets you charge forward while swinging the sword. It will easily knock away any smaller monsters in your path. This skill makes your character charge forward for 4 small hits followed by a wide slash that does a medium amount of damage.
Shadowless Prayer weapon proficiency lvl. 11
Shadowless Prayer is risky but powerful. If you are attacked when in the stance, you will quickly move behind into your foe's blind spot (at the back) and attack them. As your weapon proficiency increases, you will be able to perform an additional attack with [triangle] . A "counterattack" art, your character assumes a stance for (~5 sec). It has a startup time (~1 sec) so don't do it at the moment they attack.
True Radiant Slash weapon proficiency lvl. 15
True Radiant Slash is a charge attack in which you swing the sword around you to build up power before slamming it into its target. You can also hold down [triangle] to charge up and increase the damage done. Be careful when using this battle art as it can leave you standing there and the consquences may be dire.
Nirrti weapon proficiency lvl. 20
Nirrti will greatly increase the speed and number of your attacks, though you'll lose the ability to block. As you continue to land attacks, you will be able to prolong their effects. It's vital to evade attack as you strike your foes. Also you cannot be knocked down by most monsters and some boss moves.
