Just so you know how good it is, each lvl of you sharpshooting ring applies +1 to your bow, and also all projectile weapons. i would dump everything on that sharpshooting ring, enchant the bow, and only spend upgrades somewhere else if i found plate armour.

Huntress + sharpshooting ring = very strong. remember you can enchant the bow to make it even better, its usually worth an upgrade scroll esp. at the start of your run
