Correctly building the Pyro Traveler in Genshin Impact is a necessary step in optimizing their role as either a sub-DPS or a main DPS in team comps. The Pyro Traveler has finally become available as of Version 5.3, following their arrival in Natlan in Version 5.0. The Pyro Traveler is, at their core, an off-field sub-DPS capable of helping the party with off-field Pyro DMG against enemies, activated by their Elemental Skill. The Pyro Traveler’s kit in Genshin Impact revolves mostly around this mechanic. However, it’s possible to transform them into a main DPS, too.
