Wraithknight Dreamwalker Squad

Add the current number of models in the formation to the distance the models are allowed to move in the Movement phase, to their charge range, and to their Weapon Skill and Ballistic Skill. For example, a Wraithknight Dreamwalker Squad with 5 models would add 5" to their moves and charge range, and +5 to each model's Weapon Skill and Ballistic Skill.
