Oathmark is battle-scale miniatures wargame, featuring 32mm figures drawn up in ranks and files. Each figure is its own playing piece with its own profile: unlike in some systems, they're not just for show, with the unit base as the only mechanically relevant piece. Attacks and other actions are adjudicated by D10 rolls.

There is a dedicated miniatures range by North Star. Races include Dwarves, Elves, Goblins, and Humans.
