As part of my Dreamlands expansion, I've been fiddling with having a dreamlands specific monster cup, with only appropriate monsters (so no Mi-go, for example, finding their way there to flitter about being confused). The first draft of which is below. If you haven't read the rules for the expansion (and they are rather long), the Nightmare is basically like a Vortex, when monsters walk into it, bad stuff happens.
How many copies of each monster will be in the cup is still being worked out, although there will definitely only be one of the bottom five unique monsters. I'm thinking something like a 30 monster cup, I want a spread of monster power roughly equivalent to the normal cup, which works out to be an average toughness of 2ish, so they can't all be super giant killing machines, there has to be some cannon fodder cultists and ghouls.
Firstly, many of them are copies of existing monsters, which I have tried to keep identical, although I have used different pictures so that they are less easily confused with normal ones when putting them in the wrong cup. Ghouls I gave a bonus in the underworld, which is new but thematically appropriate for their home turf. Nightgaunts now take you to the Vale rather than Gates (which would have been impossible in the Dreamlands) and Moonbeasts take you to the moon, and are stalkers rather than aquatic (which, as they are no aquatic locations in the Dreamlands, would have been pointless).
I've tried to keep the dimensional symbols spread out, rather than having them all be Dreamlands. The idea is that a reasonable proportion should activate on each of the three types of movement cards. Mostly Moons for the Moon/cross card, Dashes for the Hex/Dash/Triangle/Star card and Diamond (Which is Leng, after all) for the Diamond/Circle/Square ones.
I don't know a great deal about what Haon-Dur and the Eidolon Lathi are supposed to be (a dark wizard and some wierd Spirit respectively?), so the versions above are kind of stabs in the dark, so anyone who knows more about the actual characters feel free to correct me.
I welcome any comments or balancing ideas for the creatures I've done, or suggestions for new monsters!
