I - Rules
(see JITD, p. 22; RTL, p. 30)
The Reach ability allows a figure to make a melee attack targeting both adjacent spaces and spaces at a range of 2. As with a normal melee attack, rolled range has no effect on the attack - it only misses if a miss result is rolled. The attacker is required to have a line of sight to the target space.
Road to Legend
The Reach ability allows a figure to make melee attacks targeting spaces one space further away from it than normal for each rank of Reach it has. As with other melee attacks, rolled range does not affect the attack - it only misses on a miss result. The attacker is required to have a line of sight to the target space.
