Hello, welcome to the forum @Goar!
Depends on what content you want to do, it can be 1v1 or 1vsMany, ManyvsMany...
Gear and skills are situational most of time.
I whold recommend just pieces of gear that are most used on regular bow.
Mercenary Hood, Friend Cowl, Hunter Hood
Mage robe, Cleric Robe, Mercenary Jacket
Guardian Boots, Cleric Sandals...
Resistance T5+ or Poison Potion T6+
My suggestion it's try them all. And experiment.
If you're looking to win and more advanced tips.
Search on YouTube for bow builds.
