Casting spells in Baldur's Gate 3 can be incredibly beneficial - if you’re casting the right ones. Some spells are simply more powerful than others. It’s not just about dealing damage, though. You want spells with incredible utility as well. No matter what Evocation Wizards may tell you, you cannot simply Fireball your way through every problem you come across.Sometimes you need a spell that disables or blinds your foes, so you can complete an objective. It’s much easier to steal an item if nobody, but you can see, after all. I’m looking at my favorite spells in Baldur's Gate 3 today.I’ve broken them down into tiers based on how useful and powerful they are in a broad, general sense. While we won’t talk about what every spell does, I’ll explain why they are in each tier.What are the best spells in Baldur's Gate 3?1) S-Tier Eldritch BlastMagic MisslePass Without TraceArmor of AgathysSleepHealing WordChill TouchGuidanceFriendsHexTasha’s Hideous LaughterFaerie FireHunter’s MarkFlaming SphereScorching RayDarknessCloud of DaggersHold PersonThese are the most useful spells in the game (Image via Larian Studios)S-Tier spells in Baldur's Gate 3 are the cream of the crop. They’re useful in such a wide variety of situations for spellcasters. They aren’t necessarily the hardest-hitting combat abilities but are the ones that have the most utility. Magic Missile is a given, as is the mighty Eldritch Blast. Healing Word is also an incredibly useful support spell.There are also control spells like Sleep, Darkness, and Hold Person. You can’t forget Pass Without Trace either, which masks the movements of you and your companions. You don’t always need to obliterate foes with fireballs, and this list shows just how many options you have.2) A-Tier InvisibilityMisty StepShillelaghSpike GrowthMirror ImageShocking GraspFireballMoonbeamAidDancing LightsChromatic OrbHellish RebukeThorn WhipShield of FaithJumpInflict WoundsWebMage HandPrayer of HealingRay of FrostBaneMinor IllusionThey may not be as useful as S-Tier, but they're not to be underestimated (Image via Larian Studios)For Baldur's Gate 3’s A-Tier spells, they’re slightly less powerful than their S-Tier brethren. However, these are all abilities that other classes are going to love. Web is one of my all-time favorites in Dungeons & Dragons, especially when combined with grease and fireball.You have Invisibility and Minor Illusion for trickery and stealth and the mighty power of Thorn Whip and Hellish Rebuke. Mage Hand might not be A-tier worthy, but I’m a fan of it as it stands right now. There is a lot of usefulness in this catalog of Baldur's Gate 3 abilities.3) B-Tier Heat MetalFalse LifeCure WoundsFire BoltProtection from Evil & GoodLesser RestorationSilenceBurning HandsRay of EnfeeblementLongstriderGuiding BoltBlade WardThaumaturgyDarkvisionFind FamiliarCommandMage ArmorFind FamiliarBlurShatterMelf’s Acid ArrowGreaseEnsnaring StrikeResistanceSacred FlameThe B-Tier options are still good, if not restrictive (Image via Larian Studios)The B-Tier picks in Baldur's Gate 3 aren’t bad, per se’. When we get to this point, these are more limited in their use and scope. For example, you don’t need Darkvision as often as you’d think. If you aren’t using a familiar, why would you want Find Familiar?When you’re dealing with Druids, you have less for Heat Metal, as another example. These are solid spells, but they’re far from useful in every situation. Protection from Evil & Good is another example - it’s worth knowing, but not everything is good or evil.4) C-Tier Hail of ThornsPoison SprayEnhance AbilityColor SprayExpeditious RetreatSearing SmiteFeather FallTrue StrikeSometimes, you just need to jump off a cliff - that's when Feather Fall is useful (Image via Larian Studios)Baldur's Gate 3 has an enormous catalog of spells, thanks to Dungeons & Dragons 5th Edition. Many of these have been around for years before that. When it comes to the C-Tier options, they’re even more restrictive than the A and B-tier options. Again, they aren’t terrible, but moment-to-moment usefulness feels incredibly sparse.5) D-Tier Enlarge/ReduceSpeak with AnimalsDetect ThoughtsBlindnessDisguise SelfTrue StrikeAnimal FriendshipRay of SicknessWitch BoltCharm PersonCrown of MadnessGoodberryArms of Hadar Lae'zel doesn't need disguise self to blend in. by u/Immawatchinyou in BaldursGate3 By the time you have spare slots for these spells as a high-level character, they really aren’t worth having. Some of them feel more like role-play abilities, which isn’t a bad thing. I can’t think of a moment in Baldur's Gate 3 where I was grateful for a Speak with Animals cast. I’ve had moments in the tabletop version where these came in handy, sure.Of course, there will be moments when every spell on this list could be used. Just because I rank them lower doesn’t mean these Baldur's Gate 3 abilities are useless. Consider what you’re trying to do, and make the right pick for your needs as a caster.
