Eberron Warlock

There’s no such thing as a typical warlock. If it was easy to make a pact, everyone would do it. Some warlocks might have gained power through sheer luck, just happening to be in the right place at the right time, when the moons and planes aligned over a particular manifest zone, allowing a deal to be struck with an extraplanar being. While other warlocks may have earned their pact through research and effort, learning long-forgotten rituals to conjure and negotiate with the patron. A warlock could be a member of a bloodline with ancestral ties to a fiend, or they might have claimed an artifact in a forgotten ruin. It’s up to the player and DM to decide how the pact was made, but always remember that every warlock is remarkable. This sort of arcane power doesn’t come easily, and every warlock should have a story. Morgrave Miscellany, page 77, gives examples of what playing a Warlock in Eberron might look like.

In addition to the subclass options presented on dndbeyond, the following Warlock Patrons are also available:

Alchemical Savant

Whether through an event the befell an ancestor, orexposure to magical potions or treatments in your own life, or a particularly potent dragonmark, your body is infused with the transmutative power of alchemy. This spark of alchemical magic within within you persists as a lightning-like energy that grants you magical powers. While other alchemists and wizards strive to create the transformative talismans called transmuter's stones, you are a living transmuter's stone.
