If you planning to go Arrow Storm build, yes Ignis Cap Type K + Virtual Bow will be your best option, and you can always refine the headgear whenever you can afford, its just u might wan to at least +11 the VIrtual Bow for extra Arrow Storm damage.
Prism ranger scarf reduce your No Limit cooldown,20%range damage and also another 0.2s Arrow Storm cooldown, assuming u satisfied the required skills from the gears.
As for leveling before reaching 130lvl (assuming you are/can get the set mentioned), you can check out Royal Bow or Gigantic Bow that allow you to any other element arrows instead of Elven Arrow (neutral)
Class Shadow sets gives 50% penetration on normal monster, which can helps you boost some damage while you leveling, it also give +10 all stats to help you instant cast Arrow Storm when you switch to Ignis Cap Type K + Virtual Bow combo
