## D&D Varant: Middle 3D20

- In this version of DnD35e instead of rolling 1d20 for each 'test' you roll three and then pick the center value as your roll. This produces the same sort of bell curve as say using 3d6 but without all the messing around with rescaling and rebasing.

- For threats, crits and fubles there are several options. The simplest is to just say that the threat range is now the crit range, this reduces the chance of a crit on average but quick to work out. The second is to say that 18 or greater is a '20' on a threat roll and 17 or greater is a '19-20', 16 is '18-20', 15 is '17-20'. After that the probs no longer work correctly

- The probs are:
