Geo Traveler functions as a main DPS with access to Geo damage and off-field elemental application through Starfell Sword, making them flexible in mixed-element teams. Pairing with a Geo sub-DPS or shielder like Zhongli or Albedo amplifies Geo damage output and provides crowd control; alternatively, combine with off-field Hydro or Pyro applicators for reaction-focused teams. Equip an ATK-scaling sword such as Amenoma Kageuchi or Iron Sting depending on whether favoring Geo or elemental reactions, paired with ATK% and Geo DMG% artifacts.
