Looking at the Mind Control ability (fourth-tier Adept), it says:
Instead of applying Effort to decrease the difficulty, you can apply Effort to increase the maximum level of the target.
Does this mean that if you use Effort, you must use it to increase the maximum level of the target? Or if you use Effort, you can use it to increase the maximum level of the target, but you can also use it to decrease the difficulty? (All emphasis is mine.)
So if I were to try Mind Controlling a level 4 creature, I'd have to spend 2 Effort because of the creature's level. Could I also spend 2 Effort to decrease the difficulty?
