Only hardening armament in my opinion.

>conquerors
Shanks scared the beast off with a glare, Zoro did that multiple times pre-ts including to the Buggy pirates
>Observation
Zoro saw the future where Rocks would fight in Alabasta after learning Breath of All Things which is Future vision. He could also hear their breath just like Voice of All Things. Enel had straight up had mantra which was just observation, could read people's movements
>Advanced armament
Zoro had this in the Daz Bones fight where he could control the power of his sword, later he could throw invisible slashes just like invisible armor. It gets confirmed as advanced armament in Udon
>Advanced CoC
Zoro used this one in Water 7, projecting his aura to create an illusion (Asura), just like Shanks can with Gryphon.

Oda had pretty much everything except basic armament under different names pre-timeskip.
