A Dislexicon,which incidentally is a term I just made up, is the opposite of an index. It is a deliberately disorderly presentation of information designed to spur creativity rather than to enable reference. It’s no good for looking anything up, but it’s great for hammering your brain with a barrage of ideas. The goal here isn’t to offer you a fully developed list of monster abilities, complete with rules and details. That’s for when you already know what you want, or might need to look something up. This book is for when you have absolutely no freaking idea what the proposed monster ought to be able to do, but you’ll make it up if someone just tells you what the ability is called.
Here’s the best way to think of it. Let’s just assume I stole a wizard’s notes for his book about thousands of monsters through history and across the planes of existence. I admit nothing, but let’s just say so. All I happened to get was the part that was supposed to be the Table of Contents, only the wizard hadn’t alphabetized it, and I chose not to, for the reasons listed in the introduction. Now you and I are in the same situation: neither of us knows exactly what all these abilities describe, but we can make some good guesses. Yours are as good as mine, unless I’m lying about the “I only got the Table of Contents” part of the story. Which I wouldn’t put past me, frankly. You’ll have to trust me on this.
