Arena is a totally different story. You will need different equipment for PvP than for PvE… Take a read here to get some info:
on how to successfully get some damage for a PvP char. Short version:
- 7x ED+
- ( WD+ optional)
- 2x PTL
- Don’t use WD% or ED%. They are bad for PvP.
Rest is up to you, which skills you want to use etc.
