There are two schools of thought when it comes to charts. Some dungeon masters love em, others hate em.
I’ve always been fond of tables such as Critical Hit and Critical Fumble. What I did not like was the lack of detail. That is, I hated that you were to use a 1d20 to roll the actual result on a table. I’m fond of my zocchihedron (d100) and I don’t get to use it often enough. With that in mind I came up with a Critical Hit chart and a Critical Fumble chart that had listings from 1 to 100. Nothing duplicated. In the tradition of the highest number is the best, that would make number 1 the worst roll. You don’t want to roll a 1 after you have rolled a fumble. I’ll post my charts over the next few weeks, but for now I want to examine my Critical Spell Fumble Chart. Feel free to adjust any of these to fit your current campaign or play style. Let’s start with the worst possble roll you can get and get better from there…
