Looking to form a coven of witches...

[Dr Mathias]

I really like the RAFM witches, I have or have owned all of them. I think Bob Murch sculpted them.

I recommend this SEXY WITCH from IMPACT! miniatures:

or you can buy her without the pumpkin:

I bought her WITH the pumpkin, but in the end I sculpted a flying broom and posed her "bewitched" style.

Hope that helps.

I've always thought that this Ral Partha/Iron Wind Metals Witch was rather under-appreciated... :

I like that one too... especially that she's offering up a pumpkin.

My scenario idea is sort of a Seven Samurai thing... a village of mundane humans who have fallen afoul of the local witches...
Each witch has a specialty, undead... nature spirits... critter hordes... minor demons... leading to a series of small battles as each witch competes with her coven sisters to menace the villagers. I'm thinking of some mechanism where they can potentially mess each other up as much as the villagers.
For their part the villagers have set up a bogus celebration of a renowned local hero hoping that they can attract some capable tourist/defenders when the witches' come calling (they're acting according to an arcane calendar that the local priest has knowledge of... survive that day and the curse will rebound on the witches)... so I'm thinking of a few rolls on a random chart of heroes to see who the humans have in town when the stuff goes down.
Originally I'd planned for WFB 3e... but now I'm not sure. I need to collect/paint the bits... make more terrain... anyway, so there is time to work on out.

I like the scenario idea... I may have to steal it at some stage!
