Spellfire Bow

This richly polished wooden longbow is ornamented with a silver trim and bowstring. Even if you aren't attuned to the bow, it creates a special arcane arrow when you draw it back without nocking one. When you fire the bow using one of these arcane arrows, you gain a +3 bonus to attack and damage rolls made with this weapon, which deals force damage instead of piercing damage. If you're attuned to the bow, you are proficient with it and can use it as a spellcasting focus. While holding the weapon, you gain a +3 bonus to any ranged spell attack you make, as the spell is launched through the bow. When you do, you perform any somatic component for the spell by drawing the bow. In addition, when you cast a spell of 1st level or higher that has a range of 5 feet or greater, its range increases by 30 feet.

Ammunition: You can use a weapon that has the ammunition property to make a ranged attack only if you have ammunition to fire from the weapon. Each time you attack with the weapon, you expend one piece of ammunition. The ammunition of a firearm is destroyed upon use. Drawing the ammunition from a quiver, case, or other container is part of the attack (you need a free hand to load a one-handed weapon). At the end of the battle, you can recover half your expended ammunition by taking a minute to search the battlefield. If you use a weapon that has the ammunition property to make a melee attack, you treat the weapon as an improvised weapon (see "Improvised Weapons").

Range: A weapon that can be used to make a ranged attack has a range shown in parentheses after the ammunition or thrown property. The range lists two numbers. The first is the weapon's normal range in feet, and the second indicates the weapon's maximum range. When attacking a target beyond normal range, you have disadvantage on the attack roll. You can't attack a target beyond the weapon's long range.

Two-Handed: This weapon requires two hands when you attack with it.

Heavy: Creatures that are Small or Tiny have disadvantage on attack rolls with heavy weapons. A heavy weapon's size and bulk make it too large for a Small or Tiny creature to use effectively.

Arcane Focus: An arcane focus is a special item designed to channel the power of arcane spells. A sorcerer, warlock, or wizard can use such an item as a spellcasting focus.
