At the start of any round of combat, a model carrying the Holdstone may declare that he is using it. Once he does, he and his unit treats flanks and rear as front for the purposes of Parry, Shieldwall and Supporting attacks (to their flanks/rear). Note that they can still be disrupted. While the Holdstone is active, the bearer must always issue and accept challenges. The unit cannot pursue any enemies in the same combat the Holdstone was used. Once the combat is over or the bearer slain, the beneficial effects of the Holdstone immediately end.
