A model striking a hated foe in close combat re-rolls all failed To Hit rolls during the first round of combat – this represents the unit venting its pent-up hatred upon the foe. After this initial blood-mad hacking, the impetus is considered to be spent – the rest of the combat is fought normally. Sometimes a model will only Hate a specific foe. Where this is the case, the type of foe will be expressed in the special rule. In the case an enemy hates a certain faction, they have the Hatred rule against all models from that army book.

In addition, model must also re-roll successful rolls to restrain from pursuit against enemies they have Hatred against. If a unit would gain Hatred in a round of close combat after the first for any reason, treat this as the first round of combat for that purpose.

If a model has the Hatred special rule from two or more different sources (such as a combination of different special rules, spells or magic items), it may re-roll failed To Hit rolls in every turn against that foe, not just the first. However, they must always pursue, with no chance to restrain.
