Since creatures and hazards are designed using almost the same math, can the elite and weak adjustments in the Bestiary be applied to a hazard, as well? For example, suppose I like the flavor and rules of a level-8 haunt but I want to weaken it to level 7 to make it more appropriate for a lower-level party. Could I just subtract 2 from everything, decrease HP based on the table, and end up with an approximately appropriate stat block?
