The third part of my Dark Angels Codex Review will look at the Warlord Traits available for the army. The Dark Angels have access to six standard traits, but also have additional Deathwing and Ravenwing traits to add to your army.
Brilliant Strategist- In your command phase, select one friendly Dark Angels unit within 6" of the warlord. Until the start of the next command phase, the unit considers the previous doctrine to be active for the attack. i.e. if the unit is in the Tactical Doctrine, then the Devastator Doctrine is considered to be active for that attack.
A decent trait for boosting the firepower of your units with selected weapons. It would be better if you could choose which doctrine was active for the unit, but there are stratagems that allow you to do this. Not one I think I would choose all that often, but could be useful with some army builds. It is not limited to core units, so your vehicles could benefit from this.
Fury of the Lion (Aura)- When a Dark Angels unit is within 6" of the warlord, if this warlord made a charge move, was charged or performed a Heroic Intervention in this turn, add 2 to the strength characteristic of that unit.
A solid warlord trait if your army is focused on assault. The one limitation is that your warlord has to have made a charge, so there is a risk you could fail the charge or your other units could fail a charge. Getting to wound most infantry on a 3+ is a big boost. This works better if you pair it with +1 to wound in combat from the Chaplain's litany.
