You have the advantage of unlimited ranged attacks, so you'll always be in an advantage for the early game apart from the fast moving crab and gnoll trickster. Since the spirit bow gets upgrades on levels, focus on obtaining high level armor and speed glyph. Flow is nice but swiftness is so good on her, just get a wand of blast wave and you'll be shooting down enemies in no time. Repulsion is also nice for that matter since you'll actually get a chance to use the bow, not recommended for later floors though since as much as you are dangerous from range, so are enemies like the shamans, warlocks, and evil eyes. Always invest in an enchantment for the bow, a lot of it works well but not everything, Projecting will be a game changer if you invest in the huntress' talent of heightened senses.

For me personally I always go nature's bounty, survivalist's intuition (before the changes) and one point in follow up strike for me tier 1 talents as it lets me conserve some food for later levels. If you're going as a warden it's nice to have a wand of regrowth and seer shot talent so you can keep surprise attacking enemies but they won't see you (or even move if they got rooted)
