Skills, also known as Weapon Arts, are special moves for Όπλα and Ξόρκια in Dark Souls 3. They are a new feature that allows the player to use special attacks with existing Όπλα or boost the damage of Ξορκιών. They vary from weapon to weapon, and can have effects such as higher damage or self-buffs.
Activating Skills
Press the L2/LT button to use the unique skill associated with the weapon you have in your left hand or are wielding with both hands. Assorted skills are available, each with their own capabilities.
Using skills consumes Focus Points (FP), which is shown in the blue gauge on your HUD, between the red HP gauge and the green Stamina gauge. FP is not required to use certain Skills, however, using a skill without sufficient FP will not yield the enhanced properties it provides. For example, the Longsword can still perform the special guard-break attack, but they will have the same damage as regular R1/RB attacks, and will not be able to break through shields as easily as it normally does. It is also important to keep in mind that using such a Weapon Art without the required minimum FP will result in the attack using significantly more stamina.
When Dual Wielding, a right and a second left handed weapon, the weapon you are two handing will be activated for it's skill when you press L2/LT. It does not matter which hand the weapon is originally assigned to, R1/RB functions remain the same. Mix and match weapons with different skills and chain them together for a more adept dual wielding build.
