(See AnyDice Web app)ДЈd6 provides 16 slots of encounters with a center point of (10-11) which accounts for exactly 25% of all rolls on 3d6 and end points described above 3/18 a total of 0.92%ДЈd8 provides 22 slots of encounters with a center point of (13-14) which accounts for 18.76% of all rolls and end points of 3 and 24 which account for a total of 0.4%Д¤d6 provides 21 slots with a center point of exactly 14 11.27% and end points of 4 and 24 a combined total of only 0.16%.ДЄt that point we could put the Tarrasque as one of the end points (0.08%) that would be a 1-8 on a 1d1000 and go with it and let it be a nice flavor encounter as opposed to a combat encounter. Rolls like 3d6 provide bell curve style probability by default. This shouldn't be too long before I can provide this.if it starts to take longer than I hope I will go ahead and make the end points less lethal for the default chart layout.ДЄs a quick aside on probability and encounter charts. Regardless of my initial motivations I plan on you providing you the ability to specify min CR max CR and whether you want the dangerous encounters on the end rolls. Two, the probability of rolling a 3 or 18 on 3d6 is 0.46% each.which means the chance of either of these super hard encounters is 0.92% per roll. One, there is no real reason you can't have encounters that you have the party encounter from a distance to help establish area depth so that they start taking time to determine that an encounter is for them or whether they should avoid it altogether. There are 2 reasons I originally did this. However, the 2 end points (3/18) have a range of EL of EL + (3-6) representing a significant encounter that probably should not be run as a real 'battle' encounter unless you want to murder your party. The central numbers are by far the most frequent so the EL range goes from EL -1 to EL +2 in general.

Could you add something to add max ranges of CR or at least limit it down a bit?The current system is based on a 3d6 roll (this will be adjustable eventually as well). For a random level 1 party I got challenge ratings scaling from 0 to 7(!). I noticed that are was a range of CR, which is neat, but it seems a bit deadly at times.

Was already having troubles making new monster-lists each time the party went a new direction. Joy! Really happy to see something new and useful, especially in the sandbox game I'm currently running.
