D&D Arcana Unleashed Gives Every Class Familiars and Reworked Magic Subclasses

Wizards of the Coast has released Arcana Unleashed, a player-focused D&D supplement for the 5.5 edition of the game, alongside a companion adventure called Arcana Unleashed: Deadfall. Polygon reviewed both products early, and the verdict is split — the main book delivers, the adventure less so.

Arcana Unleashed fills in the wizard subclass gaps left by the 2024 Player's Handbook, adding Conjurer, Necromancer, Enchanter, and Transmuter. All four get meaningful upgrades over their 5e versions. The Conjurer now unlocks teleportation at level 3 instead of level 6, usable a number of times equal to the character's Intelligence modifier — making the subclass genuinely slippery in combat. At level 6, summoned creatures gain temporary hit points and damage resistance. The Necromancer got a full redesign: it's now built entirely around raising and commanding undead, including the ability to detonate them for burst damage. The Transmuter, previously considered the weakest wizard subclass, received a rework centered on its Polymorph abilities.

Beyond wizards, the book introduces 10 new backgrounds. Nine are tied to magical factions detailed in the book, but the tenth — Familiar Trainer — is likely to be the most-played. Its origin feat, Familiar Friend, grants access to the Find Familiar spell to every class, meaning a Fighter or Barbarian can now have a magical pet without multiclassing or dipping into spellcasting. That kind of cross-class flexibility is a defining trait of 5.5 edition's design direction, and Arcana Unleashed leans into it hard. Whether that's a feature or a flaw depends on how much you value class identity.

The companion adventure, Arcana Unleashed: Deadfall, is a magical espionage story set in Thay — the Red Wizards' home territory — but Polygon's review flags it as the weaker half of the package. Arcana Unleashed follows Ravenloft: The Horrors Within, the book that kicked off what Wizards of the Coast is calling a new era for D&D, and it signals a clear pivot back toward player-facing mechanical content after that setting-heavy release.
