Models with this special rule have Dodge (6+) special rule in close combat. However, this cannot be used against enemies that attack before the model with Elven Grace.
If your opponent's army roster contains one or more models from Warhammer: Dark Elves, models with this special rule re-roll all failed Panic tests and have Immunity (Fear).
Models with this rule (but not any mounts) may re-roll all To Hit rolls of 1 when making close combat attacks.
If a unit has this rule then supporting attacks can be made by one more rank than normal for each number indicated in the bracket. This rule is cumulative with other sources of Fight in Extra Ranks.
