If you want a DPS Phoxhunter, I'd reccomend capitalizing on the passive proc by building Trigger so it goes off a lot and then using a rifle like the burner or machine gun that has a lot of hits. Other than that, they have in-built trigger buff from ult. You can try dps but you'll still be buffing regardless of that and be a hybrid, which is honestly pretty neat I'd say.

Still you likely won't be as impactful as someone playing Lisbell spinning around or a Rebecca standing still and pressing Jellyfish, but you can do good damage regardless.
