Maybe there’s something to having a base encounter HD for certain hex areas. 1/3/5/7 seems about right. And we can use this similar level chain to say: minion/elite/boss/megaboss. So in hex 1 areas an elite would be 3 HD and. Boss would be 5. In hex area 5 a a minion would be 5 Hd and an elite would be 7 and a boss would be higher, a 9. I should look at the spread of HD in odnd and BX and maybe it’s just a multiple +3/x3. But this gives us an easy way to cap areas if we know what the base...
