Enfeebling Magic

Enfeebling magic encompasses spells that hamper players and mobs. They do this by imposing negative Status Effects when cast on the target.

Effects range from Damage over Time, to lowering accuracy or defense, to lowering your stats (like STR) directly, or even slowing down your movement speed. And those are just examples; there are many other types as well.
