It's very hard to use a hammer against very fast enemies or against the crowd and almost impossible in closed spaces because your enemy will not just stand most of the time and just interrupt the Judgement cast very easily.
And now you’re probably going to say something - "Use the Weak stat that they do not run" but that doesn't really help us again so much because if you attack someone or cure someone the enemies will start try to hit you which is again will allow to interrupt the Judgement cast and in the end you’ll just forget about Judgement Hammer because the Juicing skill is more useful.
I just want to say - try to fight 3-4 goblins or pack of wolves and you’ll understand that it’s really hard to use the Holy Magic attack sometimes in fight even if you have 2 siren on your side at level 50 (COM 0, SCU 5, WIS 15, SUR 10, CON 10)
