Just a quick preview of something I’m working on for the upcoming Adventures Dark and Deep™ Game Masters Toolkit. A section of random tables. Dozens and dozens of them, each answering a question like “What does it taste like?” or “Why was he exiled?” or “What happened to me in the tavern last night?” or “Why is that mountebank here?” Just stuff to help the ol’ creative juices to flow. This is a section that was not included in the open playtest document, but is planned for the final release. Here’s one I just finished; “What has my familiar been up to?”
There was once a d10,000 table for wild magic results that had as many ridiculous entries in it for strange things going on.
The one entry that I remember with such clarity read simply "Your spellbook is plotting against you."
Gonna have to see if I can't dig that chart up again . . .
Since there's 20 entries on that table, each with a 1 in 20 chance of occuring, you could just make it a single roll on a d20.
All of the other tables use percentages, and not all have 20 entries; that's just for the sake of consistency.
