Void Hunter

As a void hunter, your body can go gaseous or ungaseous at will, allowing many different abilities. You can move and teleport by doing this, and using the void, you never have to worry about ammo again as you can easily refill your weapons by reaching into the void. 

Weapon's of the Void.

When you choose this archetype at third level, you now dual wield shot bows, though long bows are still usable. Shot bows each have a total of 4 shots in them, each shot containing a total of 2 arrows. These arrows disappear if they travel more then 15ft. Each arrow individually does 1d4 damage. When you run out of ammo, take your bonus action to reload. Throw your shotbows on the ground, and grab new ones out of the void. You can shoot twice per attack with these.

Wraith

When you choose this archetype at third level, once per short rest, enter a gaseous form, where no physical or magical attacks can hit you. This form lasts until the end of your turn in combat. In a gaseous state, you cannot make any action. In this form, your movement speed is doubled, and your shotbows are automatically reloaded.

The Void's Justice

At 7th level, for every shot that connects with a foe, heal half of the damage.

Shadow-step

At 11th level, thrice per day, you can teleport anywhere you can visibly see that is at a max range of your movement speed.

Death Blossom

At 15th level, once per long rest, as all your actions, use the void to its fullest, and empty multiple shotbows at break-neck speeds in the surrounding area. Everything in a 40ft radius of you must make a dexterity saving throw with a dc of 20, taking 20d10 damage, and half as much on succesful save.
