Luck of the Far Realms Tips in Baldur's Gate 3

Paladin Divine Smite Crit: Paladins can use a reaction with Luck of the Far Realms to guarantee a critical hit. When a Paladin has a spare spell slot, they can add this reaction to deal radiant damage on top of their normal attack damage. This allows for powerful Great Weapon Master hits, combined with a critical hit and a Divine Smite, resulting in massive damage.

Assassin Rogue Sneak Attack: Assassins focus on eliminating enemies in the first turn. By combining advantage rolls from Assassination with a guaranteed critical hit from Luck of the Far Realms using either a melee or ranged weapon, Rogues can deal substantial damage, especially against targets who haven't taken their turn yet. Stealth options further enhance this.

Colossal Slayer Ranger: This feat allows Rangers to deal extra damage against high HP foes. Using Luck of the Far Realms to guarantee an attack hit makes Rangers more effective boss killers.

Vulnerability Damage: In D&D, Vulnerability doubles damage. In baldurs gate 3, this is often applied by making a creature Wet and then hitting it with Cold or Lightning Damage. By guaranteeing a critical hit with Luck of the Far Realms, you can use your highest spell slot for a cold or lightning spell, maximize its damage due to the crit, and then double it due to the Wet status. The Blast Pendant from Act 1 can further empower lightning strikes. This combo is often seen with classes like Four Elements Monk, Druids using Lightning Grasp spells, or other niche methods of applying lightning or cold attacks.

Half-Orc Savage Attacks: Half-Orcs benefit significantly from Luck of the Far Realms due to their racial trait, Savage Attacks. This trait triples the amount of dice rolled on a critical hit, rather than doubling. Combining a Luck of the Far Realms guaranteed crit with Savage Attacks means you're rolling three dice for damage, on top of any other effects like a Paladin's Divine Smite.
