Part of this whole process of bringing monsters and dungeons and Ancient Ones (Oh my!) to The Settlers of Catan includes a certain amount of scaling back Arkham Horror as well. I’m incorporating elements of several different game systems, and trying to find the lowest common denominators between them.

This involves a certain amount of retooling. Some of you might find it distasteful, but it means scaling back some of the horrors of Arkham Horror. I’ll stop beating around the bush: I cut nearly everything that wasn’t a human mortal, or an undead monster like zombies or ghosts, ’cause those appear in Dungeons & Dragons with some frequency.

I was left with twenty-four monsters: six cultists, three ghosts, three ghouls, one high priest, three maniacs, one vampire, two warlocks, two witches, and three zombies. I actually really, really like this mix of monsters, because most of them can be fought and reasonably defeated by a lone investigator. They’re all easy to identify with, too.

Core Arkham Horror game:

x6 Cultist
x3 Ghost
x3 Ghoul
x1 High Priest
x3 Maniac
x1 Vampire
x2 Warlock
x2 Witch
x3 Zombie

From this, I created a “monster frequency chart,” which is meant for a player to roll a twenty-sided die and receive a semi-random monster. I organized the monsters roughly by their power and the challenge they represent, placing the vampire and the high priest at the bottom for those unfortunate low-rollers.

One or more cultists appear on a roll of fifteen or higher, while nearly everything else appears on one of two numbers — with the vampire and the high priest appearing on a result of a natural 1 or 2, respectively. As I said before, I figure these monsters are the ones easiest for players to identify with, so I’m going to start with them.

I want to eventually convert a lot of Arkham Horror rules to use the d20 System, and further blur the line between investigators and adventurers. Once I reach a point where I can point to items in Arkham Horror and easily say “this means that,” I’m going to have to attempt small-scale conversions first.

Of special note: I’m no longer using the rule for removing creatures from the board when gates are closed because it’s one less thing to remember. There are fewer monsters, so it works out. Also, the rule that wakes the Ancient One when the Monster Cup is empty becomes a lot more important when there are so few monsters.
