I am looking at doing an army based around that of tomb king phar who is a fluff character with no rules in the tomb king book. There is a line drawing on page 19 which is what I want to base the model on. I want him to be riding a chariot, wielding the flail of skulls and armed with a shield.

I was thinking of using settras model as the base. Changing the head of the blade of ptra to a flail and resculpting the crown to match that shown in the picture.

Does anyone have any recomendations for the conversion.

Ohh and it has to be done on a budget as it is for a tale of four gamers style thing.
