Destruction Grindstone & Shot Put
6Destruction Grindstone most noticeably affects fast, light weapons that otherwise have a hard time rapidly getting building up enemy Stagger. Tyrant Murderer's Dagger feels great with it. Raise Stagger from Grindstone, activate the Grind Fable Art to increase CritRate, stab until whiteflash-healthbar (groggy), back away, Shot Put.
Shot Puts always crumple/stagger out a groggy health bar. They're the safest way to get a stagger on enemies when you have a weapon that is either too short-range or too slow to reliably get the charged heavy off.
Salamander Dagger Handle's charged heavy is ultra-fast so it doesn't really need that, it's faster than some weapons' light attack. Tyrant Murderer's Dagger's charged heavy is actually slow, however, since the third hit has to be what connects. A Shot Put is just better.
