Ogre Tyrants, Bruisers and Hunters are able to spend points on a single big name, as detailed in the army list. The points spent on a big name add to the cost of the magic items chosen for the Ogre and are limited by the maximum amount of points the character can spend on magic items. No big name may be taken more than once in the same army.
A character with the Giantbreaker name has +1 Strength on his profile. He may never refuse challenges, and neither he nor a unit he is with may choose to flee as a charge reaction.
Any friendly units within 6" may re-roll failed Panic tests.
A Mountaineater will never be wounded on a score better than a 3+. Hits that cause automatic Wounds are unaffected.
Hunters only. When making attacks against a Large Target (either close combat or shooting), the Beastkiller gains +1 on his rolls To Wound. If the character is using a magic weapon, then he does not get this bonus.
Once per game, nominate one model in base contact that has hit the Deathcheater but not yet rolled To Wound. That model must re-roll all successful To Wound rolls this phase. This includes all rolls To Wound made by the model's mount, chariot or other extra attacks.
A character with the Longstrider big name has +1 Movement on his profile.
Brawlerguts (but not their mounts) re-roll failed To Wound rolls from their Impact Hits.
