My example comes from page 34 of The Mesh chapter, but this is a more pervasive issue. Occasionally, solid content and rules are marred by a lonely, poorly chosen word. Usually, the word is an adverb or preposition. In this case, the word is "well."
If looking in an area with multiple sensors, roll once and apply no modifiers; use superior successes to ascertain how WELL you find the smaller ones.
While the sentence works, technically, it is awkward. The better choice would be "effectively." I would suggest searching through every chapter and carefully analyzing the placement of the word "well."
(Please don't take this feedback as hostile criticism. I love this game. In the end, I will purchase it whether it contains such rare, editorial gaffes or not. I just want to give all the constructive criticism I can, as EP is a game worthy of top-quality publication and critical attention.)
