To bring new people in? I suppose we could have something like a Fantasy Island various social media? Like a public twitter or facebook page with instructions on how to find us?
A list of possible things that could be included: A map of Monster Island, Aeryn's world with descriptive areas(Like which areas are doing better, which areas need work, and where Xarin's palace is), going over basic/special skills(as you've said that Shield Expertise is definitely a thing, but hasn't been included) and things like that.
Themes for Chaos Waves.. Something that could be done is, using Tabby, do a 1d2 to find out how many in any given year we're going to have, then do a 1(or2)d12 to find out which month it's going to be in. Obviously not wanting them to run at the same time, reroll for months that are too close(like don't want a December CW to run into a January, or a March to run into an April one, etc).
As for the complexity of the CWs themselves, I don't think it was the last one, but the one before last one we had where we rolled Fighting or Psyche and depending on what color we rolled, we got a list of 50, the red being 25 I think? We can have just a regular list of 100 things or do that complex one based on a Fighting theme vs a Psyche theme? The fighters getting the better chance at more favorable options than the non-fighters and magic-ish users getting better chances of more favorable than the non-magic users. Things like that. Which can be drawn at the time of the chaos wave by a simple 1d# <-- being however many different settings we have to pick from?
