Arcana Unleashed drops in September, and the preview season is in full swing. We have enough confirmed information to give DMs and players a real picture of what to expect — and what to start planning for right now.
The Eight New Subclasses — What’s Been Confirmed
WotC has confirmed eight new subclasses for Arcana Unleashed, all focused on spellcasting classes and arcane builds. Here’s what’s been revealed so far through the preview season:
Wizard: School of Chronurgy (Revised)
An updated version of the Chronurgy subclass from the Wildemount sourcebook, rebuilt for the 2024 rules. Time manipulation abilities now interact with the new action economy — significantly more impactful than the original version.
Sorcerer: Runic Origin
Magic that manifests as visible runes written in light or shadow. The Runic Origin sorcerer can inscribe temporary runes on surfaces and creatures that trigger on specific conditions. Mechanically closest to the old Mark of scribing concept but significantly more flexible.
Warlock: The Living Library
Your patron is not a being — it’s an ancient repository of forbidden knowledge. Mechanics lean into information gathering, forbidden lore, and the cost of knowing things you shouldn’t. Thematically rich for campaign integration.
Druid: Circle of Ley Lines
Druids who attune to the magical currents running through the earth. In high-magic settings with ley line networks, this subclass becomes significantly more powerful — an intentional design choice for the Season of Magic theme.
Cleric: Arcane Domain
A divine spellcaster who draws power from gods of magic and knowledge rather than devotion. The Arcane Domain cleric blends arcane and divine spell lists in a way that previous editions gestured at but never fully delivered.
Paladin: Oath of the Arcanist
Not a paladin who uses magic — a paladin who has sworn to protect the integrity of the arcane arts themselves. Divine Smite interactions with spell slots work differently here, and the Channel Divinity options are built around magic suppression and enhancement.
Fighter: Spellblade
The most anticipated subclass in the set for many players. The Spellblade weaves spellcasting directly into weapon attacks — not Eldritch Knight-style bonus casting, but actual spell effects triggered by hit conditions. Closest to the Hexblade fantasy but mechanically distinct.
Ranger: Hex Hunter
A ranger built to track and neutralize rogue magical sources — wild magic zones, cursed artifacts, corrupted spellcasters. Adds magical tracking and dispelling tools to the ranger’s exploration toolkit in ways the class has historically lacked.
Growing Magic Items — How the System Works
The growing magic items system is the mechanical centerpiece of Arcana Unleashed. Here’s what the preview material has confirmed about how it actually works:
- Milestone-based growth: Items don’t grow on a fixed schedule — they grow when the character reaches specific milestones defined by the item itself. Some are level-gated, some are narrative conditions.
- Three tiers per item: Most growing items have three power states. The base item is fully functional and useful at Tier 1. Tier 2 unlocks at the first milestone. Tier 3 requires a significant campaign moment, not just a level.
- Attunement persists across tiers: You don’t re-attune when an item grows — the attunement deepens. This is the mechanical representation of the bond between character and item.
- DM-facing system: Growth conditions are defined by the DM, not the player. The book provides frameworks and sample items, but the DM controls when and how items evolve.
The Deadfall Adventure Module
Arcana Unleashed: Deadfall arrives alongside the sourcebook at $29.99. The Red Wizards of Thay are the central antagonists — specifically a splinter faction pursuing a forbidden magic-enhancement ritual that would weaponize the ley line network.
Deadfall is designed to run across 5 sessions for a party of 4-5 characters at levels 11–14. It works as a standalone adventure or as a capstone for a high-magic campaign that’s been running through the Season of Magic content.
What to Do Before September
Two practical things to do right now while the book is still a month away:
First — pick one subclass from the list above and think about what character you’d build around it. Don’t plan it in detail; just identify the concept. When the full mechanics arrive in September you’ll be able to evaluate them against a real character idea rather than in the abstract.
Second — if you’re a DM, identify two or three items in your current campaign that you’d want to grow. Write down what the growth conditions and power unlocks would look like informally. When Arcana Unleashed provides the official framework, you’ll have items ready to retrofit immediately.
