Beserk Charge Roll double the total number of attack dice in close combat during a turn in which they charge (based off Attack charateristic, not from bonus attack number).
Cannot parry during the turn when they charge, even if armed with swords etc.
Wolf Battle Howl Once per game at the start of any movement phase, Ragnar can utter his blood-chilling howl. When he does so all Space WOlves, including Ragnar, will charge towards the enemy. Such is the power of the Battle Howl that the charge rate is triple the normal move, and not double as normal.
The Battle Howl affects all Space Wolves except Long Fangs if you wish to ignore it for them.
