Transmuter Wizard: D&D 2024 (5.5e) Subclass Optimisation Guide

Transform matter at a whim with this buff/debuff wizard subclass, updated for D&D 2024.

At a glance

What’s changed in D&D 2024?

The 2014 school of transmutation was quite underwhelming. It lacked much in the way of raw power and really didn’t embody the idea of a transmutation expert. Instead they felt more of a dabbler in the transmutational arts. Fortunately, they’ve made loads of improvements with the new transmuter which I’ve summarised below:

• Subclass at level 3: Like all subclasses in D&D 2024, the transmuter features now kick in at level 3 rather than level 2.
• Transmutation savant: No longer makes it easier and cheaper to copy transmutation spells to your spell book. Instead, you get an extra transmutation spell known whenever you gain access to a new spell level.
• Wondrous alteration: Replaces minor alchemy which let you temporarily change something from one material to another. Now grants an enhanced alter self.
• Transmuter’s stone: Moves from level 6 to level 3. Proficiency in constitution saving throws is always granted by the transmuter’s stone.
• Empowered transmutation: Brand new feature for level 6 letting you upcast certain transmutation spells.
• Potent stone: New feature that grants your transmuter’s stone an extra buff.
• Shapechanger: Was limited to be cast on yourself and to beasts of CR1 or lower. It could be used every rest though. Now can be used for higher CR creatures and you retain more existing capabilities, including spellcasting.
• Master transmuter: Improves the options here like restore life not consuming material components and restore youth ends the exhaustion condition. Panacea only heals half HP maximum instead of all HP.

Transmuter features

Transmutation savant (Lv3) – 4/5

Like most wizards, transmuters get extra spells known for their given spell school. This means you get easy access to the likes of blindness/deafness, dragon’s breath, fly, haste, polymorph and timestop. There’s plenty of good spells there and that’s enough to be as good as any other subclass’ spell list.

Transmuter’s stone (Lv3) – 4/5

So this stone grants a buff that’s reasonable enough. Where this is better than some other standard buffs is you have changeable options and can give it to someone else. Importantly, the one consistent buff is proficiency in constitution saving throws which is really useful for the oft concentrating wizard.

Your other options are fairly standard stuff; darkvision, a damage resistance or a speed increase (+10ft). All solid and commonly used buffs. I’d be inclined to favour the speed increase as standard, but could switch to darkvision when needed or a damage resistance when facing certain foes.

Wondrous alteration (Lv3) – 2/5

Alter self is a decent spell, but it’s less good on a wizard than other classes. If you happen to be going underwater, it’s great and the bonus action dash is solid enough but that’s usually rare.

However, wizards won’t normally aim to do disguises as charisma isn’t their strength. This maybe works when the whole group is going undercover or in desperate situations, but ideally you want a bard or a sorcerer pulling off this kind of appearance changing malarky.

Natural weapons is a really terrible idea for a wizard. You really shouldn’t be trying to make unarmed strikes, even with the improved damage. The concentration boost might have been nice (notice it complements your transmuter’s stone concentration buff), but this means you’re stuck concentrating on alter self for its natural weapons which I wouldn’t care about losing concentration on anyway so this is just a near pointless option.

Empowered transmutation (Lv6) – 5/5

Upcasting transmutation spells by a level is really nice and very much pushes you to cast transmutation spells and select ones that can be upcast. Here’s a list of all the wizard spells that I think this impacts (remember, it can’t be used on spells that make an attack roll or force a saving throw):

• Animate objects
• Blindness/deafness
• Dragon’s breath (the spell doesn’t cause the saving throw, the breath weapon you’ve given someone does so I think this is allowed)
• Enhance ability
• Fly
• Gaseous form
• Jump
• Longstrider
• Magic weapon
• Spider climb

That’s a really solid bunch of spells, if not a huge list and nice to make your concentration go further with 2 flying creatures or granting an ally a +2 weapon through magic weapon, a stronger dragon’s breath or 2 targets of blindness (without expending concentration).

Technically, I don’t think this is limited to wizard spells either so if you’ve multiclassed, then you can use this on things like elemental weapon or shining smite too, but I doubt this will be particularly optimal.

Potent stone (Lv10) – 4/5

A second buff for your transmuter’s stone is handy. Tremorsense can be a useful method for tackling invisibility, though you may have spells for this already, but you can save spell slots and spells known for other things. The advantage on strength saving throws is useful as strength saving throws do come up a bit.

You should be casting enough transmutation spells at this point too, that this can become quite adaptable as well.

Shape-shifter (Lv10) – 5/5

At this point, the transmuter becomes better at being a druid than a druid. At least when it comes to wild shape. The beast form you can transform into is a much higher level (starting at CR10 and increasing with your level, not that this matters as the highest CR beast is CR8). You also retain things like your features, feats and spellcasting abilities. Importantly, you can still cast spells while in this form, though you’re limited to transmutation spells. Those transmutation spells also can’t use material components that have a cost or are consumed by the spell. Polymorph is also a concentration spell so concentration spells are out.

This doesn’t leave you with a lot of useful spells you can use while polymorphed. Blindness/deafness will be great, as is disintegrate. You might consider jump so you can leap much further round the battlefield in your new found beast form or magic weapon. They’re both bonus action spells so free up your action for beast form attacks. There’s not much other spellcasting to consider in this form.

For this reason, I don’t think you can think of this form as a way of doing all your wizardly stuff while having loads of temporary hit points for more resilience. I think you need to be using it to become an additional martial warrior and leaning hard into your beast form’s capabilities.

Beasts don’t tend to have a high CR though. 8’s the best you’ll get with a t-rex (which is very good). It can do some nasty damage and has 136 temporary hit points for you and a speed of 50ft. If you need range or a climb speed, then the giant ape is a strong option while the giant squid can help you with aquatic combat.

Master transmuter (Lv14) – 4/5

This is a sort of desperate measures kind of thing as using it will either expend a level 7 spell slot or destroy your transmuter’s stone. You can get it back after a long rest, but you likely want to keep the buffs it grants.

Major transformation seems really flexible, but is likely very difficult to gain a use for in actual play. I imagine you could create a key or a battering ram or something similar, but many obstacles you face can likely be overcome by more standard means at this level.

You then have some great healing options, including the ability to raise from the dead, remove curses and end the exhausted condition. Generally pretty nice stuff to have available.

How good is the transmuter?

The transmuter has some strong options and a load of flexibility. From an alterable transmuter stone to empowered polymorphing. They’re strong in combat and even better out of combat with a tool for most situations.

It’s also their ability switch up tactics that makes them a little more interesting as a subclass too. Tired of casting spells and just want to smash a dragon, then you can, as a t-rex no less.

They are sometimes a little limited by all the transmutation spells you’ll want to be slinging around. They tend to be more about buffs and debuffs rather than damage dealing. This can leave you wanting a few other options to use alongside your best features (shape-shifter and empowered transmutation in particular). But of course, you don’t want a transmuter for evocation, abjuration or anything else anyway.

The main criticism I would level is that it’s a little average at early levels and only really good at higher levels. For this reason, I don’t think it quite warrants the highest score. It’s still a strong subclass though.

4/5

Building an optimised transmuter

Transmuters follow mostly the same pattern as other wizards when it comes to build optimisation. You want to build for a backline spellcaster. The spells themselves may be different (a greater leaning towards transmutation spells) but other aspects of your build will be largely the same.

Below I’ve pieced together loads of advice on how you can build an optimised transmuter.

Ability scores

Recommended options

• Intelligence: Your most important ability score. You’ll need this for spellcasting prowess, knowledge skills and more uses of empowered transmutation.
• Dexterity: You’ll need this to have any kind of decent AC. You should consider grabbing the mage armor spell or the lightly armored feat to complement this and enhance your AC further.
• Constitution: Wizards have the smallest hit die in the game making them highly susceptible to damage. Upping this where you can will help make your character a bit more durable and help with concentration saving throws.

Options to avoid

• Strength: You’ve got almost no use for strength.
• Wisdom: Only useful for some skills and saving throws, otherwise, not worth investing in.
• Charisma: This is mostly for face skills which wizards aren’t that great at and you don’t have the space for.

Ability score	Point Buy	Standard Array
Strength	8	8
Dexterity	15	14
Constitution	15	13
Intelligence	15	15
Wisdom	8	10
Charisma	8	12

Skills

Recommended options

• Arcana: Common knowledge skill and you have the intelligence to back it up.
• History: Another common intelligence skill.
• Investigation: Investigation comes up a fair bit and as one of the few intelligence based classes, you’re in a good place to help here.
• Nature: This feels like the domain of rangers and druids, but as an intelligence skill, this is another that a wizard is well placed to focus on.
• Religion: Unless you have a cleric in the party, religion proficiency can be useful for all that religious lore you need to know.

Species/race

I’d look for species with the following qualities:

• Resilience: You could use your species to make you more durable. Things like extra HP, damage resistances, flight and teleportation will all help you either survive more damage, or get away from danger.
• Innate spellcasting: The more spells you have in your repertoire, the more situations you can aid your party with. Innate spellcasting will help you fulfill that role more and often give you free castings of spells too.

Recommended options

• Aasimar (2024): Damage resistances make you more durable. Some bonus action healing helps you play backup healer (an area of spellcasting wizards happen to be quite poor at). But you’re mainly here for temporary flight which will keep you a lot safer in nasty battles.
• Elf (2024): An extra skill and darkvision are both helpful but innate spellcasting is the most useful aspect for a wizard. High Elf is a good option for misty step and an extra cantrip. Drow are good for buffs and debuffs with the likes of faerie fire and darkness. Wood Elves are more about speed and stealth.
• Gnome (2024): Gnomish cunning is great against magical effects. Minor illusion and speak with animals are good utility options for a utility caster.
• Human (2024): If you need to boost your skill proficiencies to take full advantage of all those knowledge skills, then Human’s a good option. The consistent supply of heroic inspiration is useful too. I’d use the extra origin feat on the kinds of feats that can be difficult to grab through a compatible background. Things like tough are good for this, especially as this is a subclass that really benefits from lots of feats.
• Tiefling (2024): 4 extra spells known is mainly what you’re after here. I’d favour the infernal legacy as all their spells are evocation spells allowing you to enhance their damage.

Backgrounds

Backgrounds are much more important now with D&D 2024 with ability score increases, origin feats and skills all now linked to your background.

For a transmuter, I’d prioritise intelligence and then one of dexterity or constitution with the below being your best options:

Name	Ability scores	Origin feat	Skill proficiencies	Tool proficiency
Artisan	Strength, dexterity, intelligence	Crafter	Investigation, persuasion	One kind of artisan’s tools
Criminal	Dexterity, constitution, intelligence	Alert	Sleight of hand, stealth	Thieves’ tools
Merchant	Constitution, intelligence, charisma	Lucky	Animal handling, persuasion	Navigator’s tools
Mulhorandi tomb raider (HoF)	Dexterity, constitution, intelligence	Lucky	Investigation, religion	Mason’s tools
Sage	Constitution, intelligence, wisdom	Magic initiate (wizard)	Arcana, history	Calligrapher’s tools
Scribe	Dexterity, intelligence, wisdom	Skilled	Investigation, perception	Calligrapher’s tools
Spellfire initiate (HoF)	Constitution, intelligence, charisma	Spellfire spark	Arcana, perception	One kind of gaming set

Feats

Origin feats

I’d say the below are your best origin feats for a transmuter:

• Lucky: Invoking advantage and disadvantage is always handy. Consider using this for something like an upcast chromatic orb to increase the accuracy.
• Magic initiate: Grab some extra spells known from another spell list (or from your own). Wizards need a good range of spells and grabbing them from a other class list can help you fill any spellcasting gaps in the party (like becoming a backup healer with healing word for instance).
• Musician: A generally excellent origin feat for helping your allies out with some heroic inspiration (kind of like a slightly better lucky, you give to your friends).
• Skilled: If the party needs a bit more proficiency in knowledge skills, you’re a good candidate for that. This can bump up your number of skill proficiencies a decent bit.
• Spellfire spark (HoF): Some damage reduction against spells and a bonus action cantrip. The damage scales with your level too.
• Tough: Really valuable extra hit points for a subclass with few hit points.

General feats

At level 4, you can start picking up general feats. These are some of the better options for a transmuter:

• Fey touched: Misty step is great for staying safe. Plus you get more spells known. You can read my fey-touched guide for more advice
• Lightly armored: If you don’t want to keep spending spell slots on mage armor, then you could invest in this, especially as studded leather and a shield will give you better AC than mage armor.
• Mage slayer: Great for disrupting spellcasters and gives you something similar to legendary resistance. You should expect to be dealing damage most turns which gives you regular opportunities to disrupt concentration spells.
• Ritual caster: If you feel like you’re struggling to have enough of the spells you want available to you, then this is the best way to boost your utility with more spells gained through this feat than any other. You can check out my full guide to ritual casting for more tips.
• Shadow touched: Invisibility and an illusion or necromancy spell are great for a caster class.
• Spell sniper: Great for bypassing cover and getting some extra range on your spells. Pretty good for a subclass that will often be making ranged spell attacks.

Weapons

Between cantrips that get stronger by level 5+ Tyand plenty of levelled spells to cast that are even better, it’s almost always going to be better to use a spell than a weapon (or your attacks from the beast you’ve polymorphed into).

I’d grab a light crossbow and a dagger in case you get caught in an anti-magic field, a silence spell or something similar (or if you want to use them for the true strike spell). Otherwise, you should be wholly focused on magical damage.

Armor

Wizards don’t naturally have proficiency in any armor, which makes them even more vulnerable to attacks. Increasing your dexterity and grabbing the mage armor spell is the easiest way to enhance your AC.

Alternatively, you could grab the lightly armored feat for light armor and shield training. The best setup for this (studded leather and a shield) will grant you 1 extra AC than mage armor and won’t require spell slots. You may need the war caster feat if you opt for a shield though so your spell casting isn’t hampered.
