Ravenous Dissolution

Any model with this special rule adds +1 to all To Hit rolls during the first round of any close combat where they are locked in combat with a unit containing at least one enemy model with either the Daemon Unit Type, Corrupted or Psyker Unit Sub-type, or the Independent Character special rule. If an enemy unit Charges this unit when it is already locked in combat then that does count as a new ‘first’ round of combat for the effects of this special rule.
