Exploring Eberron
Exploring Eberron is an Eberron splatbook released by Keith Baker for Dungeons & Dragons 5th Edition in August 2020. It is intended as a companion for "Eberron: Rising From the Last War", WoTC's official 5e campaign guide for the setting, although its own canonicity is... hard to place.
Chapter 1: Discovering Eberron
Talks in detail about Eberron's ancient and recent history, fleshes out what Cyre was like before the Mourning, expands upon the Last War, and talks about both Eberron's approach to magic and its relationship with artificers.
Chapter 2: Races of Eberron
Expands upon five major races unique to Eberron; Changelings, Kalashtar, Shifters, Warforged, and the Elves of Aerenal.
Chapter 3: Faiths of Eberron
Talks more about religion and how it works in the Eberron world, expanding upion the role of the divine and the place of aasimars in particular before generally expanding upon the Silver Flame, the Blood of Vol, the Sovereign Host, the Dark Six, the Cults of the Dragon Below, and other "unusual" faiths of the setting.
Chapter 4: Uncharted Domains
Expands upon four particular regions of Eberron glossed over in the official book; the monster nation of Droaam, the fledgling goblin nation called the Heirs of Dhakaan, the Mror Holds, and the Thunder Sea.
Chapter 5: Planes of Existence
Expands upon the planes unique to the Orrery, the defining cosmology of Eberron.
Chapter 6: Character Options
New backgrounds, new racial profiles, new racial feats, and new subclass options.
Aasimar: Eberron's unique cosmology leads to a few unique aasimar subraces.
- Court Aasimar are born to elven parents, gaining +1 Dexterity, the Fey Ancestry and Trance traits, Elvish as a bonus language, and the trait "Guidance from the Past"; this only becomes available from 3rd level, and lets the aasimar spend an action to gain Advantage on all Wisdom checks and saves for 1 minute 1/day.
- Seeker Aasimar draw power from blood - theirs, and that of those around them, living manifestations of the Blood of Vol's creed.
- Fernian Aasimars are connected to the plane of Fernia; they use the stats of Scourge Aasimar, except they replace Celestial Resistance and Light Bearer with the traits Fernian Resistance (Fire and Necrotic), Shroud of Flame (Radiant Consumption does Fire damage, not Radiant), and Spirit of Fire (can cast Produce Flames cantrip with Charisma).
- Mabaran Aasimars likewise are connected to the plane of Mabar. They use the stats of Fallen Aasimar, except they replace Healing Hands and Light Bearer with Consuming Touch (1/day, as an action, make a melee spell attack (Charisma); target takes Necrotic damage equal to your level, you regain HP equal to half damage inflicted) and Herald of Doom (you can cast Toll the Dead with Charisma).
Aereni Elves gain +1 to either Int or Wisdom, Expertise with one skill or tool proficiency granted by race, class or background, and a Cleric or Wizard cantrip of their choice.
Ruinbond Dwarves are aberrant-tainted dwarves from the Mror Holds.
Dhakaani are the goblinoids of Eberron, gaining unique abilities compared to the "common" goblinoids offered by Volo's Guide.
Gnolls on Eberron are not the mindless monsters of 5re lore, but a fully sapient and rational people who have turned their backs on their demon worshipping past. The WotC book acknowledges this, but doesn't make them playable. This book amends that mistake.
