i got fire storm passion damage but not using with arcane wind, i’m equipped like the 2nd configuration suggested for unique, set are different (i’m traducing from italian):
2 x Seeds of Sown Gold (Continually Channeling a skill against the same enemy gradually increases the damage of that skill up to a maximum of 30%)
2 x Grace of the Flagellant (All channelled damage, sustained ground damage, and continuous damage is increased by 15 percent.)
2 x Banquet of Eyes (Damage dealt to enemies suffering from your damage over time effects increased by 15%.)
