Best Multiclass Builds in Baldur’s Gate 3

Multiclassing — splitting levels between two or more classes — can create brokenly strong characters when done right, or a confused mess when done wrong. This guide covers the rules, the planning, and the proven combos.

Multiclass Rules to Know

• You need 13 in the relevant ability for each class you enter (13 STR/DEX for martial, 13 in the casting stat for casters).
• Casters share spell slots by tier: a 1 Wizard / 2 Sorcerer still casts Sorcerer spells using the higher of the two class levels for slot count.
• Extra Attack from different classes does not stack — plan one source.

Top Multiclass Combos

1. Sorcerer 1 / Warlock X — “The Blaster”

• 1 level of Warlock gives 2 pact slots that recharge on short rest.
• Convert those into Sorcery Points → more Twinned/Quickened spells per day.
• Best for a Charisma-face caster with huge spell uptime.

2. Paladin 2 / Warlock X — “Lockadin”

• Paladin 2 grants Smite; Warlock (Hexblade) lets you smite using Charisma.
• Dump Strength, scale from Charisma, smite on every crit/elite hit.
• One of the highest single-target damage builds in the game.

3. Fighter 2 / Rogue X — “Battle Master Sneak”

• Fighter 2 → Action Surge + Battle Maneuvers; Rogue X → Sneak Attack.
• Action Surge lets you double your Sneak Attack turns.

4. Gloom Stalker 5 / Assassin Rogue X

• Initiative + stealth opener; Assassin crits on surprised enemies.
• Devastating first-round burst.

Planning Your Splits

1. Decide your core fantasy (blaster, smiter, skirmisher).
2. Take the minimum levels needed from the “dip” class (usually 1-2).
3. Pour the rest into your primary class for its capstone.
4. Keep one ability score maxed; don’t split stats.

Common Mistakes

• Multiclassing too early (wait until at least level 4-5 in your main).
• Splitting ability scores (e.g. STR and DEX both medium → both weak).
• Expecting two Extra Attacks to stack.
