Then i suggest training on the quick battle mode, because Divine judgement really takes a lot of timing to pull it right it's true, but once you do, you'll sweep by easily in the second stage, as you will counter him really easy while he's still one the same move.
May i suggest you using a Arcane Resin accesory? It will give you a 100& EX force at the beginning of the battle, and even if it's 100% breakable, you will get the effect on the beginning of each stage ;)
