Yeah, there's no way to like hack the lamps to auto-clear you or anything like that. It's just speed-enhancing stuff at the core, which is what it will probably take to hit 80+ within the time limit with any real regularity unless something is found. You still have to fight all the monsters, clear all the objectives, etc, you just do it faster.

Oh it's still cheating, I just wanted to clarify since it seemed like a lot of people were misunderstanding the intentionally-vague OP to mean something else.
