Arcus

Arcus counts as a +4 magical longbow and is always considered to be one of your hex weapons, allowing you to use your hex warrior ability with it. The weapon deals an additional 3d8 radiant damage.

Angelic Marksmanship - Whenever you hit a creature with this bow, you may chose to use your Angelic Mark feature on them, regardless of distance. Additionally attacking at long range with this weapon doesn't impose disadvantage.

Angelic Arrows - You may choose to summon an angelic arrow when pulling back the strings of the bow. These arrows deal an additional 2d8 radiant damage on a hit, and you may choose to make all damage you deal with the bow deal radiant damage.

Divine Burst - As an action you may summon up a fiery arrow, knocking it into the bow and firing it. Instead of targeting creatures as normal, you instead chose a point that you can see within the bows range. Each creature within 30 ft of that point must make a dexterity save equal to your spell save, or take 10d8 radiant damage and 10d8 fire damage as the arrow explodes. On a success, a creature instead takes half.

Divine Pierce - As an action you allow the bow to float from your hands, growing in size as a large spectral arrow of pure light appears. You may make an attack with the bow that deals all radiant damage against each creature in a 120ft line as the arrow shoots out in an instant, piecing through everything in its path. This attack deals an amount of extra d8's equal to your charisma modifier. 

Proficiency with a Longbow allows you to add your proficiency bonus to the attack roll for any attack you make with it.
