Verdict
The friendliest of the four new Wizards, and a good first Wizard subclass. The Transmuter's Stone is useful from day one and easy to understand, and a free Alter Self each day covers a lot of exploration problems. Its damage is low, so it shines in a party that already has a hard hitter.
How it plays
You hand the stone to whoever benefits most, then spend your turns on buffs, battlefield spells and problem-solving. Alter Self gives you free swimming, natural weapons or a new face once a day. At level 10 the subclass gets two big boosts: the stone can carry two perks at once, and your beast forms keep your Transmutation casting. The capstone is a once-in-a-while miracle, including bringing back an ally, which few Wizards can do.
Features by level
| Level | Feature | What it does, in short |
|---|---|---|
| 3 | Transmutation Savant | Free Transmutation spells for your spellbook: two at first, then one more with each new spell slot level. |
| 3 | Transmuter's Stone | A focus you can hand to anyone. The holder gets Constitution save proficiency plus one perk you pick: Darkvision, a damage Resistance, or +10 feet of Speed. |
| 3 | Wondrous Alteration | Cast Alter Self free once per Long Rest, with three upgrades to choose from: underwater Dash, a disguise bonus, or stronger unarmed strikes. |
| 6 | Empowered Transmutation | A limited number of times a day, certain Transmutation spells (ones with no attack roll or save) work as if cast one level higher. |
| 10 | Shape-Shifter | Polymorph joins your spellbook with one free cast per Long Rest, and you keep more of yourself in beast form, including Transmutation casting. |
| 10 | Potent Stone | Run two stone perks at once. Mighty Build and Tremorsense join the menu. |
| 14 | Master Transmuter | Drain the stone, or spend a level 7+ slot, for one big payoff: Major Transformation on a nonmagical object, curing a magical disease or curse, raising a fallen ally, or restoring youth. |
Feature names and levels follow two post-release breakdowns of the book (DungeonMister and Brandes Stoddard, September 2026), which agree with each other and with Wizards' preview on what each feature does. We haven't seen the printed text ourselves, so check your copy for exact wording.
Stone benefit picker
The stone's holder always gains Constitution save proficiency. The extra benefit is your call:
| Benefit | Pick it when | Who should hold it |
|---|---|---|
| Darkvision | Your party has a human or another species without Darkvision | Give it to the character who scouts |
| Damage Resistance | You know what you're fighting next (a dragon, a fire cult) | Give it to whoever takes the most hits |
| +10 feet Speed | A melee ally keeps arriving a turn late | Give it to the Fighter, Paladin or Barbarian |
| Mighty Build (from 10) | Someone needs to grapple, lift or carry more | Give it to your strongest character |
| Tremorsense (from 10) | Invisible or burrowing enemies | Give it to the party's front line |
Our early default: keep the stone yourself. Constitution save proficiency protects a Wizard's concentration, which is worth more than any of the extra benefits until you have a reason to pass it on.
Building one
- Ability scores: Intelligence first, Constitution second, Dexterity third.
- Savant picks: Enlarge/Reduce and Longstrider early, Haste and Fly at level 3 slots, Polymorph at level 4 slots.
- Feats: because the stone can cover Constitution saves, you can skip Resilient (Constitution) and take Alert or an Intelligence boost.
- Party fit: Haste on a Fighter or Rogue is often your best turn in a fight.
Who should pick it
Pick it if you like helping the party and solving problems more than topping the damage chart. Skip it if you want big explosions; an Evoker is the Wizard for that.
