Negative Affixes

Is negative affixes will effect even you where in Arena? For example the Epiphany Hat… Negative Effects . Increase Total DMG by 70% if you have 70% Attack speed on Gear… When you are in Arena Affixes are decreasing… Max Attack Speed in Arena is just 24% … How this is happen? Negative Effects can be used in Arena or not? Please do reply. I having my IMBA Build on Arena :joy_cat:

Use the item in the arena, then check your profile how much attack speed it needs.
