Dungeons & Dragons Playtests Four New Mystic-Themed Subclasses

Dungeons & Dragons has dropped their first Unearthed Arcana playtest of 2026, with four brand-new subclasses being tested. Today, Wizards of the Coast posted a Mystic Subclasses Unearthed Arcana playtest to D&D Beyond, featuring four magic-themed subclasses. The new subclasses include the Warrior of the Mystic Arts Monk subclass, the Oath of the Spellguard Paladin subclass, the Magic Stealer Rogue subclass and the Vestige Patron Warlock subclass.

The Warrior of the Mystic Arts is a spellcasting subclass that grants Monks the ability to cast Sorcerer spells up to 4th level spells. The Oath of the Spellguard is designed with protecting magic-casters in mind, while the Magic Stealer Rogue targets spellcasting and can empower their Sneak Attacks with magic stolen from nearby spellcasters. The Vestige Patron Warlock forms a bond with a dying god, with the god taking on a vestige form as a companion. The Vestige companion grows in power with the spellcaster. Notably, the Vestige Patron draws inspiration from the Binder from past editions of D&D.

There's no indication when or what this new Unearthed Arcana could be related to. There are several Unearthed Arcanas not currently attached to an announced D&D product, although two almost are certainly tied to a Dark Sun sourcebook.

You can check out the subclasses here. Feedback opens for the playtest on January 22nd.

True, but it’s already been pointed out that steeling friendly spells is a usually tactically poor choice.

Using your reaction when your ally casts a spell to add d6s equal to the spell’s level to your next sneak attack (with no negative effect on the spell or caster whatsoever) is a tactically poor choice? Why?

Personally, I don’t like this subclass, and will give it a flat red without qualification.

whatever skinks your boat, I guess

You're not stealing the spells: your surfing on them. And you don't need to even attack the same target: the ally's spell goes off, you get to ride the magic into your sneak attack.

I agree that the language around it isn't elegant, but it is an effective ability, and works well with your team (which is particularly desirable for a rogue, who, at least stereotypically, is not always aligned with part goals).

Its not a lot of damage tbh and reliant on party composition.
