I had a go at painting three wizards from the excellent Frostgrave female wizards sprue. Like the female fighters set, the female wizards were released after their male counterparts, and are slightly better sophisticated sculpts. I made three wizards of very different sorts, and painted them in different colour schemes.
The first wizard is a Gandalf-type who is reading out a spell from her book.
The second wizard is less subtle and was partly inspired by the elementalist in the Frostgrave rulebook. She's the only one of the three who is converted: I swapped the top of her staff (surprisingly, a skull) with a burning brazier.
The third wizard is a witch-type model. Her body is rather hunched, so I added an elderly-looking hooded head. She also got a cat familiar from the wizard sprue. I painted her to look like a classic fairytale witch, with green as a spot colour.
I happened to have a cauldron from Nolzur's Marvellous Miniatures, so I thought they'd look right standing around it, making a potion. All I need now is Macbeth.
