To beat Cazador in Baldur's Gate 3, follow these key strategies:
- Rescue Astarion Quickly: Astarion is trapped in the ritual and must be freed within three turns to prevent Cazador from completing the ritual and winning. Use the Help action to free him as soon as possible
- Exploit Sunlight Weakness: Cazador is highly vulnerable to sunlight, which stops his regeneration, deals 20 Radiant damage per turn, and imposes disadvantage on his attacks and checks. Use spells like Daylight or Sunbeam to simulate sunlight in the underground arena and severely weaken him
- Use Radiant and Magical Damage: Equip your martial characters with magical weapons and focus on radiant damage attacks, such as Paladin's Smite or anti-undead arrows, to overcome Cazador's resistance to non-magical physical damage and prevent his healing
- Area of Effect (AOE) Spells: The fight includes multiple minions like bats, ghasts, and werewolves. Use AOE spells like Fireball , Chain Lightning , or Spirit Guardians to clear them quickly, reducing pressure on your party
- Turn Undead: Clerics can use Turn Undead to neutralize ghasts and possibly Cazador himself, making the fight easier by incapacitating enemies for several turns
- Positioning and Crowd Control: Keep your party spread out and use abilities like Misty Step to position characters behind pillars or out of harm's way. Also, consider shoving Cazador off the platform for an instant kill on lower difficulties, though this is less reliable on higher settings
- Potions and Resistances: Use potions like necrotic resistance to mitigate damage from Cazador and his caster allies
- Focus Damage: Concentrate your attacks on Cazador to quickly reduce his health before his buffs from ritual sources make him stronger. Defeating or disrupting the ritual sources reduces his HP, damage, and movement speed bonuses
By combining these tactics—freeing Astarion promptly, using sunlight-based spells, applying radiant and magical damage, controlling the minions with AOE and Turn Undead, and careful positioning—you can defeat Cazador effectively even on higher difficulties
