Keybind Move Name Visual Showcase Requirements Stamina Description
E Heavy Sweep HeavySweep.gif 45 Sword Mastery 35 initial Stamina, 4 per tick (111 total) A good range block-breaker sweep, but is slow for the active frames to come out. If the user has the Gura Gura no Mi, the sweep will become larger and deal more damage.
R Shockwave Slash ShockwaveSlash.gif 75 Sword Mastery 55 Stamina One long ranged block-breaker slash projectile. If the user has the Gura Gura no Mi, it will shoot 3 of them, with a bigger AoE.
