Conclave of the Shooting Star.

Rangers of the Shooting Star conclave emulate the brilliant displays of astral bodies streaking across the sky. Their arrows strike with the intensity and variety of these extraterrestrial phenomenon.

Level 3 Feature:

Star Motes.

Starting at 3rd level, you learn to conjure motes of starlight. As a bonus action, you can expend a spell slot to conjure motes of starlight that encircle you. You conjure three motes with a 1st-level spell slot, creating one additional mote for each spell level higher than 1st. You can have a number of motes equal to your ranger level. Any additional motes you create disappear. These motes last until they are used or until you finish a long rest.
If you have four or more motes remaining, they shed bright light in a 20-foot radius and dim light for an additional 20 feet. If you have one to three motes remaining, they shed dim light in a 20-foot radius.
You can expend a mote to make a ranged spell attack that you can use with the Attack action. The attack has a range of 120 feet, and on a hit the target takes 2d6 radiant damage and is pushed 10 feet away from you.

Shooting Star Technique.

At 3rd level, you learn the three Shooting Star techniques.
Illuminate. As a bonus action, you can expend a mote to imbue a piece of ammunition with starlight. The ammunition sheds dim light in a 5-foot radius until the end of your next turn, after which it returns to normal. When you hit a creature with this piece of ammunition, it takes an additional 1d6 radiant damage, sheds dim light in a 5-foot radius until the end of your next turn, and the next attack roll made against it before the end of your next turn has advantage.
Scattered Sparks. As an action, you can expend a mote and launch it at a point within 120 feet of you. Each creature within 10 feet of that point must make a Dexterity saving throw against your ranger spell save DC. A creature takes 2d6 fire damage on a failed save, or half as much damage on a successful one. This damage increases to 3d6 at 7th level, 4d6 at 11th level, and 5d6 at 15th level.
Comet Shot. When you miss a ranged weapon attack or ranged spell attack, you can expend a mote to use a bonus action to reroll the attack roll against a different target within 60 feet of the original target. On a hit, the attack deals an additional 1d6 radiant damage.

Level 7 Feature:

Luminous Defence.

At 7th level, the power of the stars comes to your aid in times of need. When a creature moves within 30 feet of you, you can use your reaction to make a mote attack at the creature.

Level 11 Feature:

Starlight Strike.

At 11th level, your attacks become infused with starlight. Whenever you hit a creature with a weapon attack, it takes an additional 1d6 radiant damage.

Level 15 Feature:

Conjure Mote.

At 15th level, you learn to create starlight motes with your own powers. You can use an action while you have no motes to create one mote.
