Pretty much what TigerKnee said.
My deaths lately consist of accidentally clicking on a level 9 something while mousing next to a black square during low level exploration or overlooking "new features" like Count Blah-Blah's fireball retaliation that he never had the first bazillion times I beat him
Just a quaint little box that says "You will die." and two buttons that say "K." or "Nevermind." would be sufficient (possibly disabled if you have any kind of dodge chance).
Honestly I used to be against this idea, and I have posts lying around here to prove it, but it's happened enough times to get really annoying.
