Trait: Stuff of Legend

Many of the Space Marine chapters are old and well known to their enemies. Others specialize in Terror tactics or maintain some tradition that makes them seem super-natural in some way. This trait costs +2 pts per single wound model and +5 pts per multi-wound model. Any unit that is charged by any unit from an army with this trait must pass a leadership test with -1 modifier or the unit that is being charged will only hit the charging unit on 6s.
