The lower my fatigue is, the less chance I have of successfully casting a spell, and the higher it is, you know how it goes. I can't seem to recall what mod I downloaded that changed the gameplay like this.I didn't even think I installed a mod that changes the gameplay. Could it be from the Morrowind Code Patch? Don't tell me it's naturally part of the game where the fatigue does determine your success.

That's how the game works.

It's naturally part of the game.

At least there aren't armor penalties...
