The Stars are mighty, powerful, and unyielding. An unending pull of force to all within their reach. Barbarians following the Path of the Starcallers follow their doctrine – warriors that channel the very pull of the stars with their rage.

There are many ways to attain this path, some come from tribes that have followed the stars for decades. Others look to study the multiverse at large. Some, while they are called barbarians nonetheless, are scholars of the stars, capable of reading them and deciphering their secrets.

Collapsing Star

Starting when you choose this path at 3rd level, your strikes represent the weight of a collapsing star. While you're raging, whenever a creature within 5 feet of you moves away from you, you can use your reaction to do a special opportunity attack that deals extra force damage equal to 1d6 + half your barbarian level. If this attack hits the creature will have to do a Strength saving of a DC of 8 + your proficiency bonus + your Strength modifier or be pulled back to a place within 5 feet of you and have their movement set to 0.

Starcaller's Light

At 3rd level, your essence is merged with that of the stars. As a bonus action, you can start emitting dim starlight in a 10 foot radius around yourself, this counts as dim light. When you are raging this light will instead become bright light in a 20 foot radius, and dim light for an additional 20 foot radius.

You can end this light at any time as a free action.

Gravity Well

Starting at 6th level, you have learned to harness the weight of the stars. While you are raging, as a bonus action you can force all creatures of your choice within 15 feet of you to make a Strength save of a DC of 8 + your proficiency bonus + your Strength modifier or be pulled within 5 feet of you. If a creature can not be pulled within 5 feet of you it will instead be moved as close as possible.

You can use this ability a number of times equal to your proficiency bonus, and you gain all expended uses when you finish a long rest.

Starcaller's Stance

At 6th level, you learn to harness the impossing presence of the stars. While raging you are immune to being knocked prone or moved against your will.

Supernova

At 10th level, you learn to channel the might of a dying star. As a bonus action, you unleash a explosion of bright star light, momentarily illuminating everything within 120 feet of you with bright light, all creatures within 10 feet of you must make a Dexterity saving throw, taking twice your barbarian level in radiant damage on a failed save, or half as much on a successful one. Additionally you gain temporary hitpoints equal to your barbarian level + your constitution modifier. As long as you have these temporary hitpoints your body is enwreathed with stardust, shedding light.

Once you use this feature, you can’t use it again until you finish a long rest.

Starcaller's Rage

Beginning at 14th level, the stars reside within you, empowering your body.

While you’re raging, at the start of your turn, you regain hit points equal to your Constitution modifier per round. 

You do not get these hit points if you are unconscious, stunned or incapacitated.
