Kraggi

Kraggi is treated as a unit Champion and fights with his forge tongs (counts as a hand weapon) and wears an apron to protect him from the intense heat (light armour).

While Kraggi is alive Thorek gains one extra dice per turn to cast runes with. However, it's important to keep track of which one this is (by using a different coloured dice, for example) because if this extra dice rolls a 1 Kraggi has done something wrong and the rune is miscast.
