The strongest all-round Wizard build in Baldur’s Gate 3 is the Divination Wizard: Intelligence 17, Dexterity 14, Constitution 14 at level 1, Portent dice to force failed saving throws, and a spell list built around Hypnotic Pattern, Counterspell and Hold Monster. If your party already has a dedicated controller and you simply want to delete packs of enemies, Evocation is the better subclass, because Sculpt Spells lets you drop Fireball onto your own front line without damaging your allies. Both builds run on the same skeleton — Intelligence first, Constitution second, and every level spent on spells that either end a fight or stop one from starting.

Quick comparison: the four Wizard builds worth building
All four use point buy and assume a race that can contribute at least +1 Intelligence. “Difficulty” here means how much babysitting the build needs from the rest of the party in the first six levels.
| Build | Best for | Level 1 ability spread (after racial) | Signature feature | Difficulty |
|---|---|---|---|---|
| Divination | Best overall — control and reliability | 8 / 14 / 14 / 17 / 12 / 8 | Portent (level 2): replace any attack roll or save with a rolled die | Moderate |
| Evocation | Best for raw area damage | 8 / 14 / 14 / 17 / 12 / 8 | Sculpt Spells (level 2): allies automatically save against your evocations | Easy |
| Abjuration | Best for solo runs and Honour Mode | 8 / 14 / 16 / 16 / 12 / 8 | Arcane Ward (level 2): a damage-absorbing pool that refills when you cast abjurations | Easy |
| Bladesinging (added in Patch 8) | Best melee hybrid | 8 / 16 / 14 / 17 / 10 / 8 | Bladesong: bonus AC, concentration protection and movement speed | Demanding |
Best overall: the Divination Wizard, level by level
Divination wins because Wizard damage is replaceable and Wizard reliability is not. Portent gives you a small pool of pre-rolled d20 results each long rest; spending a low one on an enemy’s save against Hold Monster or Dominate Person is worth more than any damage spell in the game, because a failed save removes a target from the fight entirely rather than chipping at its hit points. It also rescues you from your own bad luck — per the class feature description, Portent can replace any attack roll, saving throw or ability check made by you or a creature you can see.
Ability scores and why each number matters
| Ability | Point buy | Level 1 final | Target by level 8 | Reason |
|---|---|---|---|---|
| Strength | 8 | 8 | 8 | Dump stat; nothing a Wizard does keys off it |
| Dexterity | 14 | 14 | 14 | +2 initiative and +2 AC, giving AC 15 with Mage Armour |
| Constitution | 14 | 14 | 14 | Concentration saves keep Haste and Hypnotic Pattern alive |
| Intelligence | 15 | 17 | 20 | Drives spell save DC and spell attack rolls |
| Wisdom | 12 | 12 | 12 | Perception checks and resisting charm effects |
| Charisma | 8 | 8 | 8 | Dump stat; let a party member talk |
To hit 17 Intelligence at level 1 you need a race that contributes +2 to the stat — the gnome subraces are the straightforward route. If you would rather play a Githyanki, you get +1 Intelligence instead and start at 16, which costs you exactly one point of spell save DC until level 4. In exchange, Githyanki medium armour proficiency pushes your resting AC from 15 to 17 without spending a spell slot on Mage Armour, and Astral Knowledge covers the skill checks your dump stats would otherwise fail. That is a real trade, not a downgrade.
The level-by-level plan
| Level | What you take | Why it matters |
|---|---|---|
| 1 | Cantrips: Fire Bolt, Ray of Frost, Minor Illusion. Spells: Shield, Magic Missile, Grease, Chromatic Orb | Shield is a reaction for +5 AC and will save your life more than any damage spell |
| 2 | Divination subclass — Portent | Two pre-rolled d20s per long rest; hold them for boss saves |
| 3 | Misty Step, Web, Scorching Ray, Hold Person | Web is the best level-2 control spell in the early game; Misty Step escapes grapples |
| 4 | Ability score increase: +2 Intelligence (19) | Spell save DC rises to 15 with a +3 proficiency bonus |
| 5 | Fireball, Counterspell, Hypnotic Pattern, Haste | The biggest power spike in the game; Counterspell shuts down enemy casters outright |
| 6 | Divination subclass feature — The Third Eye | Free Darkvision and See Invisibility; fixes the class’s reliance on light |
| 7 | Polymorph, Greater Invisibility, Wall of Fire, Ice Storm | Polymorph doubles as removal and as an emergency heal for a downed ally |
| 8 | Ability score increase: +2 Intelligence (20) | Save DC reaches 17 before gear |
| 9 | Cone of Cold, Wall of Force, Hold Monster | Wall of Force splits encounters in half with no save allowed |
| 10 | Second subclass feature; scribe any scrolls you have been hoarding | Your Portent pool and utility expand at the point gold stops mattering |
| 11 | Chain Lightning, Disintegrate, Globe of Invulnerability, Otto’s Irresistible Dance | Sixth-level slots; Globe trivialises caster-heavy Act 3 fights |
| 12 | Feat: Alert, War Caster or Resilient (Constitution) | Alert for initiative, War Caster for concentration; take the one your party lacks |
The other three builds, and who each one suits
Evocation — best for players who keep hitting their own tank
Evocation’s level 2 feature, Sculpt Spells, lets you nominate allies inside an area spell and have them automatically succeed their save, taking no damage from a successful one. That single line turns Fireball and Cone of Cold from situational into every-turn tools. Take it on a first playthrough if you are tired of repositioning before every cast. The trade-off is that you have no answer to a boss who saves against everything — you cannot force a failure the way a Divination Wizard can, so your damage ceiling depends on enemy positioning.
Abjuration — best for solo runs and Honour Mode
Arcane Ward builds a pool of absorbable damage that refills whenever you cast an abjuration spell, and Shield, Counterspell, Mage Armour and Glyph of Warding all feed it. A well-played Abjuration Wizard at level 12 is genuinely hard to kill, which matters when a single lost fight ends the run. The cost is offence: you are spending turns and slots maintaining a shield instead of ending encounters, so pair it with at least two damage dealers.
Bladesinging — best melee hybrid, hardest to pilot
Patch 8 added Bladesinging, which trades the pure caster fantasy for a Dexterity-and-Intelligence skirmisher. Bladesong boosts your AC, protects your concentration and increases movement speed, and the subclass expects you to be in melee range where a d6 hit die hurts. It rewards tight play and punishes sloppy positioning harder than any other Wizard option. If you want to swing a sword, this is the build; if you want to win reliably, it is not.
Gear priorities by act — where the real power sits
Wizard gear is unusually simple: almost everything you want either raises spell save DC, raises AC, or protects concentration. Exact numbers on individual items have shifted between patches, so read the tooltip before committing a slot.
| Slot | Early priority (Acts 1–2) | Late priority (Act 3) | What you are buying |
|---|---|---|---|
| Staff | Melf’s First Staff | Markoheshkir | +1 to spell save DC and spell attack rolls; Markoheshkir adds a free spell per short rest |
| Head | Any +1 DC focus or a spell-attack circlet | Hood of the Weave | Another +1 spell save DC |
| Cloak | Cloak of Protection | Cloak of the Weave | +1 AC and +1 to saves early; a DC bonus later |
| Body | Mage Armour (no armour proficiency) | Robe of the Weave | DC bonus without giving up your spellcasting |
| Amulet | Anything with a utility cast | Amulet of Greater Health | Sets Constitution to 23 — enormous concentration insurance |
| Rings | Ring of Protection | Ring of Protection plus a DC ring | +1 AC and +1 to all saving throws |
Worked example: how spell save DC actually adds up
A level 12 Divination Wizard with Intelligence 20, a +4 proficiency bonus and the gear above ends up at 8 + 4 (proficiency) + 5 (Intelligence modifier) + 1 (staff) + 1 (hood) + 1 (cloak) + 1 (robe) = 21. Without any gear the same character sits at 17. That four-point gap is the difference between an enemy needing a 14 to save and needing an 18, and it applies to every single target spell you cast for the rest of the run. This is why the Weave accessories are worth chasing before any damage item.
How to choose, in one table
| Your situation | Pick | Reason |
|---|---|---|
| First playthrough, four-person party | Divination | Portent patches bad rolls and guarantees key control spells land |
| You keep catching your own melee in Fireball | Evocation | Sculpt Spells removes friendly fire entirely |
| Solo run or Honour Mode | Abjuration | Arcane Ward absorbs the burst damage that ends runs |
| Party already has a Bard or Sorcerer controlling fights | Evocation | Overlapping controllers waste turns; bring damage instead |
| You want a gish with a weapon in hand | Bladesinging | Bladesong makes melee viable without abandoning the spell list |
| You are playing on Explorer difficulty | Evocation | Raw damage clears encounters fastest with the least setup |
Common mistakes and the upkeep nobody mentions
- Dumping Constitution. Every control spell you cast is a concentration spell. A broken concentration on Haste can cost you an entire fight, so 14 Constitution is a floor, not a luxury.
- Standing in the open. Your AC is 15 with Mage Armour and 12 without it. If you skipped Mage Armour, you skipped your armour.
- Forgetting Shield. It is a reaction, it costs a level-1 slot, and it grants +5 AC until your next turn. Wizards who never use reactions are Wizards who die to archers.
- Wasting Portent dice. Spending a low roll on a random lockpick is a waste. Bank them for the fight’s biggest saving throw.
- Ignoring scroll scribing. Wizard is the only class that can permanently learn spells from scrolls, and the fee scales with the spell’s level. Budget a few hundred gold across a run and you effectively gain extra spells known for free.
- Skipping the long rest ritual. Mage Armour lasts until your next long rest and costs nothing but a slot you recover anyway — recast it every morning.
