Ragnarok, Oden's Paradise techniques, Thunder Bagua, all are touching Ad.CoC techniques.
Just like no touch CoA > touch CoA,
No touch Ad.CoC > touch Ad.CoC as well.
Whats there to not understand? Lmao.
Also CoA is still the important factor in it. Ad.CoC alone can't do anthing, it adds fuel to fire which is CoA.
Also, Ad.CoC Yamato couldn't break explosive cuffs for this reason. She didn't know ad.coa.
