"Higher-Level"
 

While playing Munchkin, my friends and I began debating what the term "Higher Level" means on certain cards.

For example;
A Level 16, Undead Monster
The Wight Brothers
"Will not pursue anyone of Level 3 or below. Higher-Level characters lose 2 levels, even if they escape.

Bad Stuff: You are reduced to Level 1."

Our concern was, what exactly indicates a "Higher-Level". Is it the highest level character in the game? Is it the highest of the 10 levels beginning with Level 6? Does it mean the levels higher than the level the specific card states it will not pursue; in this scenario, Level 4 and above (because it will not pursue Level 3 or below)? Or does it concern the highest level character(s) in combat?

Please, please, please do not post the same question on both this forum and the Munchkin forum. I fragments the discussion, and it does not get you an answer any quicker.
