improving D&D monster encounter tables

2016.01.21 (updated : 2016.01.20)

I've devised a random monster encounter table that utilizes the distributions I've built on this page. Click the 'graph' button about 1/3 of the way down the page (or see the bottom of this page).

My list puts all the big bads at the beginning of the range, and puts all of the aberrations, slimes*, etc at the bottom. Rolling a d16 + d10 (black line) gives a nice flat curve across the middle, but tapers off perfectly for the top-most and bottom-most parts of the range. So, the big bads and horrors are less likely to come up.

But in some conditions, you *want* those big bads and horrors. It can be done using the same table. I roll 3d6 and add up the lowest two if I'm interested in trolls & hill giants (blue line). If I'm interested in aberrations, I roll 3d6 and add up the highest three, then add 14 (orange line).

Finally, there's my (almost eight-year-old) son and his low-level character. Still using the same chart but a different selection: 2d6 + 7 (green line). This cuts out the things that will kill them outright, and keeps the neutral encounters, the pranksters, easier confrontations, etc. I decided to make my own monster encounter tables because the second thing my son ever ran into – on the first day of gaming, at age six – was an eight-sided hydra. As he likes to say, "no fair".

*I replaced the traditional slimes with a type of demon that's essentially the "grey goo" of nanotech fears.

four distributions for determining random monsters from a D&D table

output 1 d16 + d10

output 2 14+ [highest 2 of 3d6]

output 3 [lowest 2 of 3d6]

output 4 7 + 2d6

The man who lies to himself and listens to his own lie comes to such a pass that he cannot distinguish the truth within him, or around him, and so loses all respect for himself and for others. And having no respect he ceases to love, and in order to occupy and distract himself without love he gives way to passions and coarse pleasures, and sinks to bestiality in his vices, all from continual lying to other men and to himself.

—Fyodor Dostoevsky, The Brothers Karamazov
