Dian Cecht works exceptionally well with knight-based team compositions. Her ultimate ability provides significant melee attack bonuses to knight allies while applying healing over time effects to the entire team. Her active ability creates protective shields for all members and applies damage reduction buffs. While her raw healing output may be lower than dedicated healers, her offensive support capabilities compensate for this limitation. Teams featuring characters like Lancelot or Kay will see substantial performance improvements with Dian Cecht's support.
