Kosveret Patron

Warlock Subclass — Homebrew for Heretics of the Old Gods

Overview

This subclass uses the Sorcerer-King Patron rules as written in the Unearthed Arcana 2025: Apocalyptic Subclasses document. The features, mechanics, and class progression are unchanged. What follows is the patron-specific spell list and description for this option.

The Sorcerer-King Patron chassis is shared across four options in this setting: Thesik, Barani, Kosveret, and J’mon Sa Ord — all ancient beyond mortal reckoning, all outliving the world they were born into.

Kosveret was once a quiet, homesick elf who found his first real friend in the person who pulled the most elaborate prank ever played on him. He was the god of joy. He laughed constantly. He was, by all accounts, the most fun person in any room he entered.

He is not that anymore. The millennia in the orb have taken whatever held him together and scattered it. He encompasses many personalities now, few of which are aware of one another. He spends much of his time wandering — psionically projecting himself across vast distances, impersonating people both real and legendary, following interesting things until they stop being interesting, then rewarding or destroying them depending on how they strike him in the moment. There is no predicting which version of Kosveret will answer a summons. There is no predicting what he will want. There is no predicting what he will find funny.

A warlock serving Kosveret is serving someone who might send them on a vital intelligence mission and then show up halfway through to ruin it because he got bored. Or might give them exactly the insight they needed at the exact right moment, for no discernible reason. The power is real. The guidance is not reliable. The warlock has chosen to serve a chaos engine wearing the face of a god of joy, and they should make peace with that before they start asking for things.
