F2P Follow-Up Team
Herta alone won't be able to deal a lot of DMG, especially in F2P. A Main DPS like Serval will help you deal enough DMG to trigger follow-up attacks. The Remembrance Trailblazer is a great pair with Herta to deal massive amount of AoE DMG through Follow-up attacks and True DMG.
Erudition Duo Team
Herta can synergize amazingly with The Herta in this Erudition team. Use Herta's Follow-up attacks to regenerate energy for the Big Herta.
Simulated Universe Remembrance Team
This Herta team is great in the Simulated Universe game modes as long as you choose the Path of Remembrance. Herta can easily Weakness Break mobs with her AoE attacks while March 7th can Freeze enemies with her Ultimate.
