Those who wield magical abilities cannot delve into them as deeply as one might assume. As though they are restricted by invisible chains, their magic limited to some certain aspects. And this limit isn't just about healing magic or curses from the games, which are considered as Godly magic in people's perspective.
For instance, someone proficient in water magic can't magically boil or freeze it. Absolutely insane abilities like invisibility don't exist since none of the elemental powers people wield can achieve that, create the root of the ability.
They can't even change the terrain through magic.
Yet, other than Gods, certain beasts possess the capability to utilize magic to a remarkable extent. As it's a matter of envy for people, questioning their capabilities as people can use their brains to greater expenses than monsters, monsters naturally became a hot topic of research.
