Some months ago, I noticed a difference between the Core and Condensed editions in the way the Will skill is described. I would like to know whether this is an intentional change between editions (or 'editions' - whatever you call the subtle variations in the crunch between the books), or whether all the functions attributed to Will in Core are to still be attributed to it in Condensed; and, if it's the former, which Skill(s) should take over those functions.
To be more specific, Core's description of Will includes the following:
You can use Will to pit yourself against obstacles that require mental effort. Puzzles and riddles can fall under this category, as well as any mentally absorbing task, like deciphering a code. Use Will when it’s only a matter of time before you overcome the mental challenge, and Lore if it takes something more than brute mental force to get past it. Many of the obstacles that you go up against with Will might be made part of challenges, to reflect the effort involved.
Contests of Will might reflect particularly challenging games, like chess, or competing in a hard set of exams. In settings where magic or psychic abilities are common, contests of Will are popular occurrences.
In contrast, Condensed's description of Will doesn't even hint at anything like that, instead portraying Will is a pretty much exclusively reactive, not proactive, Skill (in fact the only one in the list that is like that):
Will: Mental fortitude, the ability to overcome temptation and to withstand trauma. Will stunts let you ignore mental consequences, withstand the mental agony of strange powers, and hold steady against enemies who provoke you. In addition, a high Will rating gives you more mental stress or consequence slots (page 12).
