The main one is the Kuja Arrows, you need Conqueror Haki to permanently apply Armament to them..
The only person who can do that is Boa Hancock or any previous Empress who had CoC..
Here's an attack where Boa has to infuse CoA + CoC in conjunction with her Devil Fruit..
Pistol Kiss and Slave Arrow.. Pistol Kiss hurt Luffy even though her powers has no effect on him..
Another CoA based application of CoC with Doflamingo..
Attack Bullet String..
The Classic Parasite String is also CoA + CoC..
Then you have the same type of technique being used by Ace..
Flame Spear..
Katakuri also use a similar CoA technique to detach his mochi from himself with base CoC..
Attack Name: Burning Mochi..
Then there's Cracker using CoA + CoC for his Extra Hard Biscuit Soldiers..
In fact probably every attack from Devil Fruits made into distinct projectiles are CoA technique applications of CoC..
I'm thinking of..
Kizaru: Yasakani No Magatama
Aokiji: Ice Block- Partisan
Akainu: Meteor Volcano
Marco: Pheonix Brand
Then there's is Wano specifically, for a higher level Swordsmen again CoA technique application of CoC..
Starting with Roger's Kamusari.. Great Grade Blade + CoA Hardening + Base CoC..
Not all instances where Swords and Guns are involed require CoC for unleashing an airborne CoA attack for example..
And the reason for this is because Swords and Guns in One Piece have special abilities of their own especially high quality weapons..
Kiku & Izo using Hakied up attack with each of their special weapons..
Kawamatsu mixing Haki with Fishman Karate..
Zoro infusing Black Rope Dragon twister with Haki due to Enma..
Enma Pulling Haki from Zoro as it was unstable at the time..
Zoro using another Black Rope Dragon twister in Fishman Island due to in this case Black Blade Shusui..
So Zoro master Enma unleashing for the first time his Base Conqueror Haki, achieving at the same
time a new type of CoA technique application of CoC, which was shown by Roger previously..
Dragon Damnation..
A new CoA energy Blast for Swordsmen typically requiring CoC, just like the Kuja Arrows needing CoC to infuse CoA and
Doflamingo's Bullet String.. Everything is related..
Here Yamato utilized an inferior version of the same technique Zoro recently accomplished since she does not have
a special weapon, she had to imbue CoA + CoC to reach the same level CoA Technique of Black Rope Dragon Twister done by Enma and
Shusui.. If she wielded a Sword of the same Quality as Enma or higher she could attain the same level of CoA Technique than Roger and
Zoro did with the Black Energy Blasts..
Of course if her weapon is also a special class then it's different but that doesn't seem to be the case..
Even Kaido who is a Yonko, has a Named Kanabo and Advanced CoC, can't use Black Energy CoA rays techniques..
For he doesn't have a high enough quality weapon like Great Grade Blades and higher..
Anyway, the new CoA technique applications of CoC are in no way shape or form linked to AdCoC..
