An HQ choice, a Terminator Chaplain brings a range of benefits that fit a lot of forces – starting with a Leadership of 9 and the appropriately titled Spiritual Leader ability that lets Core units from the same Chapter use that Leadership, making them even more likely to pass Morale checks. Keep your Terminator Chaplain at the heart of your formation to pass this benefit to as many units as possible, and your Space Marines will truly know no fear.
The Chaplain’s Litanies of Battle can further enhance your army. He has the Litany of Hate, which allows nearby Core and Character units to re-roll missed melee attacks. He can also choose one other Litany from a selection of six to suit the way you want to play. If you’d like a friendly unit to hit even harder in close combat, try the Exhortation of Rage. If you’d rather stand back and shoot with terrifying accuracy, the Recitation of Focus is your friend.
