Officer (Epic Battles)
The Officer is an Epic Battles role which focuses on directing and supporting the Rohirrim in battle.
You can issue orders to tell the defenders to heal, boost their damage, change their target priority or swap stances.
As you trait deeper the power of your commands increase and their cooldown decreases.
Any ally that features the text "Awaiting Orders", such as Rohirrim Commanders, features a special command UI that can be opened by using them. From there you can give the NPCs orders that change their behavior in battle and provide them short term bonuses. This includes telling them to heal, take out shields, prepare for siege fire, focus on defeating sappers first, or shaking off a corruption. The potency, cooldown, and variety of orders you are allowed to give can be upgraded, improved, and unlocked through the Promotions tab of the Battle for Helm's Deep panel.
