This 3D model of a man with sabre-tooth pelt cloak brandishing his spear and yelling, or a woman shouldering her spear and relaxed, can be either barbarians or druids. They are quite tribal. They wear little armour but make for intimidating characters with their angry yelling. Choose from either a male or female version.
