Bardadin Build Guide — BG3's Strongest Sword Bard / Paladin Hybrid

Bardadin At-a-Glance

Why Bardadin Dominates BG3

Bardadin's strength comes from compounding small advantages across two CHA-stacking classes. Sword Bard (College of Swords) at level 3 gains Blade Flourishes — special attack maneuvers that you use during a normal attack action, costing one Bardic Inspiration die per Flourish. The three Flourishes are: Slashing (2 melee attacks instead of 1, each dealing weapon damage + inspiration die bonus damage), Defensive (1 attack + temporary AC bonus = inspiration die value), Mobile (1 attack + push target 3m + move yourself without OAs).

Slashing Flourish is the engine. At Sword Bard 3, you spend 1 Inspiration die to make 2 weapon attacks plus add an inspiration die (d8 at level 5+) of damage to each. At Sword Bard 6, this stacks with Extra Attack — making Slashing Flourish into 3 attacks per Action (Extra Attack + Slashing Flourish's bonus = 3 total). Each of those attacks can be Divine Smited (Paladin 2 grants Smite). With CHA 20, your weapon attacks use CHA via Pact-equivalent feature (Sword Bard doesn't grant CHA-attack scaling directly — use a Pact-bound weapon if multiclassing Warlock, OR rely on DEX for finesse weapons like rapier).

Aura of Protection (Paladin 6) is the highest-impact party feature in the game. All allies within 3m gain +CHA modifier (up to +5 at CHA 20) to all saving throws. This is the difference between failing and passing critical saves against Hold Person, Banishment, Dominate Person, and Honour Mode boss legendary abilities. Bardadin parks the Aura on top of the most-targeted party member (usually Shadowheart or Gale, who need save protection most).

Bardic Inspiration scaling is the third multiplier. At Bard 5, Inspiration dice become d8. At Bard 10 (Lore variant), d10. Bardic Inspiration is a Bonus Action — give it to an ally to add an Inspiration die to their next ability check, attack roll, or save. Combined with Cutting Words (Lore 3 reaction: subtract Inspiration die from enemy attack roll), Bardadin actively buffs the entire party every turn without spending their own Action.

Magical Secrets (Lore Bard 6 or Sword Bard 10) unlocks access to any spell from any class. This is why Lore Bard 10 / Paladin 2 is a competitive alternative — it grants Magical Secrets at Bard 6, letting you steal Counterspell, Fireball, Spirit Guardians, and other top-tier spells from Wizard/Cleric lists.

Combat Rotation — Burst and Sustain Turns

Turn 1 setup: Open with Channel Divinity Vow of Enmity (Action) on the priority target. This costs your Action but grants Advantage on attacks for 10 turns — pays off across the entire fight. Bonus Action: Bardic Inspiration to your strongest ally (Karlach gets it most often for her three-attack turn) OR cast Bless (concentration, 4 targets gain +1d4 to attack rolls and saves for 10 turns).

Turn 2 (core damage turn): Action = Slashing Flourish (costs 1 Inspiration die). This makes 2 weapon attacks (or 3 with Extra Attack at Bard 6) each dealing weapon damage + Inspiration die bonus + Smite (if you choose to spend a slot). At Bard 6 + Paladin 6: 3 attacks per Slashing Flourish. Each attack: 1d8 (longsword) + 5 (CHA) + 1d8 (Inspiration die) + 1d4 (Strange Conduit) + 1d4 (Radiating Orb from Belligerent Skies) = ~22 base. Smite a 2nd-level slot: +3d8 = ~13 more damage. Three Smited attacks = ~105 damage per turn at level 12.

Reaction usage: Lore Bards have Cutting Words — react to subtract an Inspiration die from an enemy's attack roll, ability check, or damage roll. Use this to negate boss critical hits or important enemy concentration breaks. Sword Bards don't have Cutting Words; their reaction is for Opportunity Attacks instead (or Shield reaction if multiclassed Wizard).

Aura management: Aura of Protection requires allies to be within 3m of you. Position yourself to keep the aura on at least Shadowheart and Gale (the squishy casters). If you're in melee while they're at range, the aura is useless. Solution: stand between the melee line and the caster line, OR have Shadowheart cast Spirit Guardians and stand next to her (her aura damages enemies, your aura saves her).

Inspiration economy: At Bard 5+, Font of Inspiration refills all Bardic Inspiration on short rest. At level 12 with CHA 20, you have 5 Inspiration dice per short rest. Slashing Flourish costs 1 per use. So you have 5 Flourishes per short rest, or ~15 per long rest. That's enough for every meaningful fight to be a 3-attack Flourish turn.

Concentration management: Bless (1st-level) is the standard turn-1 concentration. Drop Bless for Hypnotic Pattern when facing a swarm (5+ enemies, AoE incap). Drop Bless for Hold Person against a humanoid boss (paralyzed target = auto-crit from melee). War Caster prevents most concentration breaks; Advantage on CON saves means you almost never lose concentration.

Sword Bard vs. Lore Bard — Which to Pick?

Sword Bard 6 / Paladin 6 prioritizes raw damage. Slashing Flourish + Extra Attack + Smite = ~100+ damage per burst turn. The build has minimal spell utility — Bard spells are limited to 3rd-level, Paladin spells to 2nd-level. You're a damage dealer with strong saves (Aura of Protection) and party buffs (Bardic Inspiration).

Lore Bard 10 / Paladin 2 prioritizes utility and party control. You only get 1 attack per Action (no Extra Attack at Bard 6 because Lore Bard doesn't grant it — Sword Bard 6 specifically grants Extra Attack as a subclass feature). Your damage per turn is lower (~30-40 instead of 100). However, you have Magical Secrets access to 4 spells from any list — typical picks are Counterspell, Spirit Guardians, Fireball, and Haste. You can cast 4th-level Bard spells (Greater Invisibility, Polymorph, Dimension Door) and 5th-level (Hold Monster, Animate Objects).

Honour Mode preference: Lore Bard 10 / Paladin 2 is the most popular Bardadin variant in Honour because Counterspell + Spirit Guardians + Cutting Words reaction protection prevents the legendary action cascade that kills runs. Sword Bard 6 / Paladin 6 is more popular on Tactician because the damage output is higher and most fights end before resource economy matters.

First-time player recommendation: Sword Bard 6 / Paladin 6. The build is straightforward — Slashing Flourish + Smite is one easy rotation. Lore Bard requires understanding Counterspell timing, Spirit Guardians positioning, and Hypnotic Pattern targeting. Sword Bard plays itself once you understand Flourish + Smite. Switch to Lore Bard variant on second playthrough.

Sword Bardadin vs. Lore Bardadin

Verdict: Sword Bardadin wins on raw damage. Lore Bardadin wins on utility, spell access, and Honour Mode survival. For first Honour run: Lore Bard 10 / Paladin 2. For damage-maxing Tactician runs: Sword Bard 6 / Paladin 6.

Bardadin vs. Lockadin

Verdict: Bardadin has more party utility (Inspiration, skill checks, Cutting Words on Lore variant). Lockadin has more smites per day and a stronger ranged option (Eldritch Blast). For party face Tav, take Bardadin. For ranged-melee hybrid Tav, take Lockadin.

Common Mistakes with Bardadin

• Starting Bard instead of Paladin. Paladin 1 grants heavy armor proficiency; Bard 1 does not. Always start Paladin for the armor proficiency. You can still go full Sword Bard from level 2 onwards.
• Forgetting Slashing Flourish costs 1 Bardic Inspiration die. Some players think it's free. Without dies, Slashing Flourish doesn't work — and you might be saving them for Inspiration buffs.
• Wasting Magical Secrets on niche spells. Common bad picks: Wish (cool but no slot to cast it on a 12-class character), Power Word Kill (single-target nuke, situational). Stick to Counterspell, Spirit Guardians, Fireball, Haste, or Hypnotic Pattern.
• Using Vicious Mockery in melee. The damage is bad and the Disadvantage debuff is wasted if the target is dead from Smite next turn. Vicious Mockery is for opening rounds against ranged enemies.
• Not stacking Bardic Inspiration uses. At Bard 5 (Font of Inspiration), Inspiration refills on short rest. At CHA 20, you have 5 dice per short rest. Use them generously — they refresh.
• Concentrating on Bless when Hypnotic Pattern is available. Bless is 1st-level and modestly useful. Hypnotic Pattern (3rd-level Bard) incapacitates 5+ enemies in a large radius. Bless is for trash, Hypnotic Pattern is for boss waves.
• Choosing Defensive Flourish over Slashing in damage fights. Defensive adds AC = Inspiration die value. Slashing adds an extra attack. Two attacks at +1d8 damage each is better than +d8 AC in most situations.
• Skipping Vengeance subclass for Oath of Devotion. Devotion's Sacred Weapon (CHA to attack rolls) is similar to Pact of the Blade's CHA scaling but worse because it's once per short rest. Vengeance's Vow of Enmity is permanent Advantage for 10 turns — strictly superior.
