Bows

The bow is a type of weapon that deals ranged damage and utilizes arrows as ammunition. The damage and knockback of a given shot fired from a bow is calculated by adding the base damage and knockback of the bow itself with the damage and knockback of the arrow it fires, so even if a bow doesn't have any knockback, the shot it fires will still have knockback to it (it's worth noting, however, that the critical strike chance from the arrows does not stack with that of the bow). Bows, like other projectile-based weapons, can shoot through platforms from both above and below.

Molten Fury
The Molten Fury is unique from other bows in that it, as its description states, "Lights wooden arrows ablaze." Any Wooden Arrow fired from the Molten Fury still deals the damage of a Wooden Arrow, but, like a Flaming Arrow, will inflict the "On Fire!" status effect to its target. In addition, if the arrow is "refunded," it will be a Flaming Arrow.
