How do i mod dificulty?

[Afreet]

Does anyone know what some of the difficulty variables mean? Below is the section of logic.txt that deals with difficulty, with each variable split into 4 options, but what do they mean? "bossatk" and "bosshp" are easy, as is "money", but is "exp" the amount of experience you receive, or is "spexp"? They go in opposite directions... "alead" I think would be the leadership of the enemies you encounter, which is the variable I'm most interested in, but can anyone confirm this? Thanks!
