As far as we know, level has nothing to do with it. Actually, wait, we DO know - there's no difference between level 1 and level 800 Union Demons.

The most important thing is element. If you're weak against their element, then your chances are WAY down. Also, if you're the same element, then your chances are down a bit. If you're strong against their element, then your chances go up a fair amount.

Second is the natural hitrate of the spell. This is something you'll just learn over time - some Hime miss their debuffs WAY more than others. Particularly AoE debuffs tend to have much lower hitrates, even when there's only one enemy.

You can increase your chances of landing debuffs with the Soul Mordred's VoF skill. With VoF, elemental advantage, and 6% from Accessories (which you probably can't do yet if you're still doing the story) most Hime will reach 100% hitrate.
