Outside of koh I donβt think he can use koh attacks with his other blades
Ok not a mode but a temporary style with a time limit
Koh onigiri he uses excessive haki through all his blades. Using coc and coa but more armament
He was also able to use a not koh version of bird dance that used both coc and coa. Him liking not using an overwhelming amount of haki
Koh Sword serpent uses excessive coc and coa again but more conquerors
But yeah zoro can seemingly use both armament + conquerors in all his styles
- Can use conquerors without koh mode at all
- Can use conquerors in koh mode
- Can use conquerors in koh serpent mode
