Marked Prey
At the start of your Command phase, select one unit from your opponent's army. Until the start of your next Command phase, each time a WAR DOG model from your army attacks that enemy unit, if the unit is visible to the attacking model, that attack has [SUSTAINED HITS 1]. The detachment then carries a KEYWORDS clause that is a genuine army construction rule, and it is the only unit-count requirement in either Knights faction: your army MUST include three or more WAR DOG units; WAR DOG units from your army gain the BATTLELINE keyword; and when mustering, you select three WAR DOG units which have the CHARACTER keyword until the end of the battle. The mirror's own designer note spells out what that last clause is for: those selected units can be given Enhancements, and one of them can be your WARLORD. This whole block is mirror-sourced text, cross-checked against the pack's amendments, and it is flagged as such.
