Hero or Valour
Infantry, Hero, Dwarf, Erebor
A model wearing an Elven cloak has the Stalk Unseen special rule
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.
