My gear consists of 3x magic which makes me a DPH veno that hits like a truck and quite frankly it's the funnest thing ever. But I do also have physical defense 10% on my chest piece.
I do however recommend you try rolling Patakas with at least 2 lines of defense levels and a purify weapon.
Also, get a vit tome alongside having a magic one to wear in foxform when tanking and trying to focus on strictly debuffing in mass PK.
In all honesty it depends on you and what you want and are planning to do in-game. Strictly mass pk? Aim for tankier gear. Smaller pk/1v1s? Aim for channeling or magic or even a mix of both works.
