Hellebron

Unit always strikes first
If the unit's Initiative is equal to or higher than the enemy's, he can re-roll failed misses when striking in close combat.

To represent their fighting fury and lack of self-preservation instincts, Frenzied troops have the Extra Attack and Immune to Psychology special rules.

Re-roll Missed attacks during the first round of close combat against High Elves

Models with this special rule (but not their mounts) re-roll all To Wound rolls of a 1 when making close combat attacks.

Attacks wound automatically on a to-hit roll of 6.
