This playstyle focuses on using their Skill and Burst to trigger support-based weapon and artifact passives while dealing Pneuma damage with their Skill. This is only recommended if a source of Pneuma is required and Traveler is your only source of Pneuma-aligned damage.
The guaranteeable 4-star can also provide an Arkhe attack for other characters, further diminishing Hydro Traveler's usability if this weapon has been obtained.
Do not use Hydro Traveler unless you need them for Pneuma mechanics and do not own yet.
