Hero or Valour
Infantry, Hero, Dwarf, Erebor
At the beginning of each fight, Gimli can choose to use either an axe in each hand, in which case he fights with 3 Attacks, or use his two-handed axe.
If Legolas and Gimli are in the same army then keep a track of how many models they have both killed. If at any point Gimli has fewer kills than Legolas, then Gimli receives a +1 bonus To Wound whilst in combat.
