In any case, these are not bad parameters even for some demons. But skills are extremely important. You can evaluate their progress in the corresponding section of the game interface. This is the main feature of the gameplay, because Celica must study and gain experience, becoming an experienced mage and not having a special dependence on artifacts. She can also use sexual tactics, but this is not necessary.
You don't actually have to let the monsters have their way with Celica. But, getting the SP multiplier that it results in is very helpful for learning skills. Plus, doing so can be a tactical advantage to stall out fights in some cases. And, there are some monster-characters that you have to lose to.
Don't worry about that stat too much, since there is a way to reduce it.
