The Mist rules almost make as much sense. Question: if Mist is in effect (not KGP) at how many ranges are a +2 Mist in effect? My guess? At only one range, 12 hexes only, as at 7-11 it's a +1 and 13-18 it's a +3.
You don't need to "guess" the answer, the rules state it very clearly (E3.32). The EX spells it out! The answer to your question is "13-18".
The
poor part of the mist rules is that there's no simple game descriptor for the condition of "increased intensity" (applicable to Rain [E3.51] and Falling Snow [E3.71]). Ideally we would have "rain/heavy rain" and "Falling Snow/heavy Falling Snow" or something like that. Instead, if we want to be consistent with the way the rules are worded, we need the just-flows-off-the-tongue "rain/snowfall with increased precipitation intensity". Interestingly, I've never seen a scenario that doesn't just say "heavy rain/snowfall" instead, which fortunately everyone understands even though the term appears nowhere in the rules.
The other bugbear of mine is that the rules have no simple way of saying "it's
currently raining/snowing". If the scenario SSR states that the Weather is Overcast (E3.5), is it raining when play begins or not? Is it snowing? I'd argue that the rules have it both ways, with one answer for rain and the opposite answer for snow.
The
E3 Temperate Weather Chart describes as one possible condition "Overcast". E5 says "EC are determined normally
until it rains" (my emphasis). To me that strongly indicates rain only happens by random chance on the Wind Change DR. OK. However the
E3.7 Snow Chart has the possible condition of "Falling Snow". E3.71 says "Falling Snow is always accompanied by Overcast conditions,
even if the snowfall ends. Falling Snow
re-occurs on a Wind Change DR ..." (my emphasis). It seems clear to me that this means the scenario
starts with the snow already falling, i.e., the opposite of rain.
These finer distinctions seem lost on many scenario designers (and even more players). For bonus points, with a strictly literal reading of the rules, you get additional "fun". E3.71 never says that Falling Snow
replaces rain, so that "accompanied by Overcast conditions" phrase means that you can have Falling Snow
and rain! The weather outside is
frightful!
So, yeah, Chapter E has issues.
None of that is even taking into account the one weather rule that desperately
needs to be changed:
E3.75 DRIFTS. The random creation of Drifts can occur in
any scenario where Ground/Deep Snow is present. How many people (esp. designers) remember that? It wouldn't be a big deal except that (a) the Drift generation procedure is incredibly clumsy and can bring any game to a screeching halt while you fart about pulling out the counters labelled "A"-"GG"; and (b) unless you're playing a scenario consisting of exactly one whole regular geomorphic board,
you're screwed. The rules make absolutely
no allowance for the placement of Drift counters on half-boards or multiple boards (let alone other non-standard board configurations). You quite literally just have to
guess in those cases. The rule needs to be re-written to make it more flexible, and more importantly,
invoked by SSR only! I would never shake my head at anyone who plays with a "no Drifts!" house rule.
