- The heavy Underdark focus across two consecutive UAs strongly hints at an upcoming Underdark-themed sourcebook from Wizards of the Coast.
The Underdark Just Got a Whole Lot More Playable
Wizards of the Coast is clearly going deep — literally — with its Unearthed Arcana playtest series in 2026. Just weeks after the first Underdark Options UA introduced the Path of Ceremorphosis (a feat progression that slowly turns your character into a Mind Flayer) and explored the lore of Deep Imaskar, the second installment has now dropped. Underdark Options 2 landed on D&D Beyond on September 10 and brings three new subclasses and five new species to the table — all dripping with the chaos, fungi, and eldritch weirdness that makes the Underdark one of D&D’s most beloved settings.
This is playtest material, so it’s not final. These options are free to download and use with your DM’s agreement, they won’t be in the D&D Beyond Character Builder yet, and they can’t be used in Adventurers League events. But Wizards of the Coast actively wants player feedback to shape where this content ends up — and the feedback survey opens on September 17. For players who’ve been hungry for something wilder to play than the standard humanoid fare, this batch is legitimately exciting.
The New Subclasses — Freedom, Spores, and Faerzress
The three new subclasses each bring something meaningfully different to their respective classes, and the design philosophy running through all of them is rooted in the Underdark’s themes of mutation, liberation, and strange magic.
Freedom Domain Cleric
The Freedom Domain is probably the most thematically surprising subclass of the batch — not what you’d immediately associate with the Underdark, which is generally known for tyranny, slavery, and drow politics rather than liberation movements. But that’s actually what makes it interesting. This is a Cleric dedicated to fighting back against those forces: a high-Dexterity build built around “magic of liberation, movement, and free thought,” serving divinities who protect everyone’s right to determine their own destiny.
Mechanically, the Freedom Domain Cleric packs a spell list loaded with movement-related options — including a Channel Divinity that mirrors the Freedom of Movement spell — alongside the notable perk of not needing to wear armor. The thematic hook is a Cleric who travels light, moves fast, and laughs at conditions. There’s even a rolling table for how your character personally defines “freedom,” which adds a surprisingly rich roleplaying dimension. Community reception has been warm toward the concept, with players noting it fills a distinct philosophical niche in the Cleric roster that was previously missing.
Circle of Spores Druid
The Circle of Spores is the subclass veteran players will recognize — it’s been a popular Druid option since its original appearance in earlier editions, and this is its official update for the 2024 revised rules. The update leans harder into the Underdark theming than ever, making this the standout subclass of the batch according to most early community analysis.
The core fantasy remains intact: Druids of this circle find beauty in decay, viewing death not as an ending but as transformation — a new form of life. In practice, that means the ability to animate and control corpses using spores, similar to how Myconids operate in D&D lore. The subclass also opens up access to Telepathy as players advance through the levels, giving the Circle of Spores Druid a surprisingly cerebral late-game identity alongside its fungal necromantic abilities. This is the subclass for players who’ve always wanted to be the creepy mushroom person who raises dead enemies and then talks to everyone inside their head simultaneously.
Faerzress Sorcery Sorcerer
The Faerzress Sorcery Sorcerer is the most esoteric and mechanically unusual of the three new subclasses — and it’s generating the most divided discussion in the community. Faerzress, if you’re not deep into Underdark lore, is the ambient magical radiation created by Lolth that permeates much of the Underdark’s cavern systems. It mutates creatures exposed to it over long periods and disrupts teleportation and divination magic in its vicinity.
A Sorcerer mutated by Faerzress gets access to abilities centered on manipulation and control: enhanced Darkvision, the ability to grant magical properties to mundane weapons, and at higher levels, the power to create Faerzress zones and lace their spells with faerzress energy — preventing targets from teleporting and blocking Divination spells. It’s a subclass built around denial and interference more than raw damage output, which is a genuinely novel identity for a Sorcerer. Community feedback is calling it “wildly situational” in some scenarios but noting real promise for the right player who builds around its denial toolkit intentionally.
The New Species — Five Creatures You’ve Never Played as Before
Five new playable species arrive with Underdark Options 2, and several of them represent genuine firsts in D&D history. For BG3 fans especially, some of these will feel like stepping directly into the game — only now from the other side of the encounter table.
Drider
The Drider is probably the most jaw-dropping addition from a pure “I can’t believe this is actually playable now” standpoint. This marks the first time in official D&D books that a Drider has been a playable PC species. Driders are the result of Lolth’s curse — a drow transformed through dark ritual into a half-drow, half-spider hybrid. Mechanically, the Drider takes heavy inspiration from the Centaur species (another large, multi-legged character type), and includes wall-climbing abilities, the ability to cast Web and Faerie Fire, and immunity to movement penalties from similar Web effects.
Community discussion is already wrestling with the practical challenges of playing an eight-legged creature — fitting through doorways, sitting in inns, navigating city environments — which are the same logistical hurdles the Centaur faces. Some players are calling it a definitive “monster” species that strains believability in standard settings. Others are already planning Underdark campaigns where a Drider adventurer makes perfect contextual sense. Either way, its inclusion is bold, and it’s the kind of character option that makes a genuinely memorable visual at the table.
Myconid
The Myconid might be the cleanest win in the entire batch, and it’s the one receiving the most universally positive community feedback. This is the first Plant-type species to be playable in D&D 5.5e, and the design does an excellent job of translating the iconic Myconid monster mechanics into something that actually works for a player character.
Myconids are bipedal fungal folk who live in colony-based societies, and both their visual identity and their mechanics lean into that communal nature. They have 120-foot Darkvision, 30-foot natural Telepathy, and can emit Rapport Spores to extend a telepathic network to nearby party members. The signature ability that’s generating the most excitement is Skill Meld: through a post-rest melding ritual, Myconids can allow one party member to share a Skill Proficiency with the entire group until the next rest. Planning a heist? Your Myconid gives everyone Stealth. Heading into a diplomatic encounter? Everyone suddenly has Persuasion. The design elegance here is remarkable for a species that could have easily been “just a mushroom person.”
Myconids have been beloved in D&D lore for years, and their colony in Baldur’s Gate 3 — headed by Sovereign Spaw and the memorable Baelen situation — introduced them to an enormous new audience. This species option feels like a direct gift to that fanbase.
Illithidkin
If you’re a BG3 player, the Illithidkin will look immediately familiar. These are humanoids who have been experimented on by Mind Flayers — touched by Illithid power through tadpole infection or other means — without completing the full ceremorphosis transformation. Think of your Tav after eating one too many tadpoles and developing the face veins. Mechanically, Illithidkin get Telepathy and resistance to Psychic damage, reflecting their partial mental transformation. The community has found them functional but somewhat underwhelming compared to the flashier options in this batch — “meh” is the word being used — though the lore hook is undeniably compelling for players building a specific character concept around being a Mind Flayer experiment who resisted full assimilation.
Kuo-toa
The Kuo-toa are fish-like subterranean humanoids best known for their ability to literally create gods through the power of collective belief — one of D&D’s most wonderfully bizarre lore concepts. As a playable species, they’re amphibious with a swim speed, have scales that shift color with extreme emotions, and carry the Slippery trait giving them advantage on rolls to escape Grapples and Restraints.
Their signature mechanic is a unique version of the Find Familiar spell: Kuo-toa can conjure a “Deific Manifestation” — a celestial idol made of mismatched Underdark parts that inherits traits and actions from two different creature types simultaneously, including options like a Homunculus or a Myconid Sprout. It’s chaotic, creative, and completely on-brand for a species whose relationship with reality and divinity is already deeply weird. Players interested in highly customizable familiar builds are already excited about the implications.
Deep Imaskari
The Deep Imaskari are descendants of ancient human empire survivors who have connected themselves to Unlight — a synthetic, artificial form of luminance that functions as a substitute for sunlight in the lightless depths of the Underdark. Lore-wise, they’re one of the more obscure corners of Forgotten Realms history, and this playtest is doing interesting work to bring them into the modern edition’s framework.
Their unique hook is the ability to “create light wherever they go” — specifically Unlight, which interacts with the Underdark’s magical ecosystem in ways regular light doesn’t. The mechanics include some interesting Aura-based effects that community feedback has flagged as potentially overpowered even at once-per-long-rest rates, suggesting this one needs the most polish before it reaches final release.
What All This Underdark Focus Might Actually Mean
Here’s the meta-story that’s generating the most speculation: Wizards of the Coast has now released two consecutive Underdark-focused Unearthed Arcana documents in the space of a few weeks, covering subclasses, species, feats, and lore hooks that span the full breadth of classic Underdark content. That’s not accidental.
The last time D&D properly explored the Underdark in a major dedicated sourcebook was 2015’s Out of the Abyss campaign. That’s over a decade ago, and the game has expanded dramatically in every direction since then. A new Underdark sourcebook — something covering the drow city-states of Menzoberranzan, the Faerzress ecology, the Deep Imaskari enclave, Myconid colonies, and all the creatures now appearing in these UAs — would fill a genuine gap in the 2024 edition’s sourcebook library.
There’s also tantalizing speculation that the project might involve R.A. Salvatore, the author who did more than anyone to define the Underdark through his Drizzt novels. He’s been reported to be working on a D&D “Icons” release, and if that’s connected to Underdark content, the lore implications could be extraordinary. Nothing is confirmed, but the pattern in these playtests is hard to ignore for anyone paying close attention to Wizards’ roadmap.
D&D in 2026 and Beyond
This new Unearthed Arcana lands in the middle of an incredibly busy year for D&D across all formats. The 2024 revised Player’s Handbook and its associated rulebooks have been landing steadily throughout the year. Earlier releases this year brought the Gothic horror-focused Ravenloft: The Horrors Within and Arcana Unleashed, which expanded the spell library significantly. Looking ahead, a World of Warcraft crossover expansion is coming in late 2026, and a Star Wars collaboration is planned for 2027 — two of the most ambitious crossovers the TTRPG has ever announced.
On the video game side, Warlock: Dungeons and Dragons is shaping up as D&D’s next major interactive release. Announced at the 2025 Game Awards and developed by Invoke Studios (now a Wizards of the Coast subsidiary), the game casts players as Kaatri — a veteran warrior who makes a pact with the iconic D&D character Tasha to wield otherworldly magic. Its first gameplay was shown at Gamescom Opening Night Live 2026, featuring the open-world Darkon setting, a magic system built around combining spells for free-flowing combat, and the full performance capture of Tricia Helfer as Kaatri and Maggie Robertson as Tasha. It’s targeting a 2027 launch on PS5, Xbox Series X/S, and PC.
There’s a lot happening across the TTRPG and digital D&D space right now, and the Underdark UAs suggest that the tabletop game is building toward something big in that classic setting. Get your feedback in when the survey opens September 17 — this is exactly the kind of content that benefits from direct player input shaping the final product.
Speaking of RPG-adjacent news this week, it’s been a genuinely packed few days. WoW Forever launched its beta today with its own community-driven character customization news, and PS Plus added RuneScape: Dragonwilds to the catalog as a day-one launch — another survival RPG hitting subscribers right now if you want something to play while you wait for these new D&D options to finalize. And if you’re a tabletop player who also games on PC, the Steam Deck 2 and component crisis news is worth keeping an eye on for when you want to take your next Drider or Myconid campaign on the go. Elsewhere, Insomniac’s response to Marvel’s Wolverine’s mixed reception is a reminder that community feedback shapes products in every corner of gaming — D&D’s UA playtest process is basically the tabletop equivalent of that same dynamic.
