Sunwing Bow

Sinew harvested from a suneater owlbear's spine can imbue arrows with low-level radiation, which is passed onto a target when struck by the ammunition. The magic of suneater respiration lies in their photometabolism; they can convert sunlight into pure, concentrated radiant energy, unleashing unholy beams of destructive force.   The wielder gains a +3 bonus to attack and damage rolls made with this magic weapon.   Sunshot. While in sunlight, this bow doesn't need ammunition. If you draw this weapon's bowstring without nocking an arrow, it produces its own ammunition, automatically creating a radiant arrow when you make a ranged attack with it. The attack deals radiant damage instead of the weapon's normal damage. The arrow created by this weapon vanishes the instant after it hits or misses a target.   Irradiation. A creature that takes radiant damage from this bow becomes magically marked for 1 hour. During this time, it leaves an invisble trail that can be seen by creatures with truesight or creatures using the detect magic spell. The trail fades after 1 hour.   When attuned to the weapon, you gain the Solar Beam and Daylight property and has 3 charges. The bow regains 1 expended charge daily at dawn. If it is exposed to dawn's light, it regains all expended charges instead.   Solar Beam. As an action, you can expend 1 charge to fire a beam of solar energy in a 5-foot-wide, 60-foot-long line originating from you. Each creature in the area must make a DC 16 Dexterity saving throw, taking 6d8 radiant damage on a failed save, or half as much damage on a successful one.   Daylight. When you take the Attack action, you can use one attack to fire a radiant arrow from this bow at a surface within the bow's range and expend 1 charge. A magical effect identical to the daylight spell manifests for 1 hour, centred wherever the arrow strikes the surface.
