1. Understanding Spells Known in BG3

In Baldur’s Gate 3 (BG3), the concept of “Spells Known” is fundamental to how different caster classes function. Each class has a unique method for acquiring and utilizing spells, influencing their strengths and playstyles.

Automatic Spell Acquisition: Classes like Clerics, Druids, and Paladins inherently possess a comprehensive understanding of their class’s spell list. Upon leveling up, they automatically gain access to every spell available to their class at that level. This provides versatility and adaptability, allowing these classes to respond to diverse combat and exploration scenarios.
Selective Spell Learning: In contrast, Wizards, Sorcerers, Bards, Warlocks, and Rangers follow a selective approach to spell acquisition. At character creation, they choose a limited number of spells to know. Subsequently, when leveling up, they can add two additional spells from their class’s spell list. This necessitates careful consideration and strategic planning to ensure a well-rounded repertoire that aligns with their intended role within the party.

It’s important to recognize the distinction between these two approaches when evaluating caster classes. The ability to access every spell offers flexibility, while selective learning encourages specialization and resource management.

1.1. Domain and Oath Spells

Clerics and Paladins receive bonus spells specific to their chosen Domain and Oath, respectively. These bonus spells enhance their capabilities and reinforce their unique identities within the game world.

Clerics: Clerics gain extra spells from their Domain, reflecting their deity’s influence and granting them access to specialized abilities aligned with their divine calling.
Paladins: Similarly, Paladins gain extra spells from their Oath, reflecting their commitment to a sacred code and granting them access to abilities that embody their chosen ideals.

Crucially, Domain and Oath spells do not count against the normal limit of spells a caster can prepare. This means Clerics and Paladins can always have these spells ready for casting, in addition to the spells they choose to prepare after a long rest or at level up. However, it’s important to note that Domain and Oath spells still require a Spell Slot just like other spells.

1.2. Wizards and Spell Acquisition

Wizards have a unique ability to expand their spell repertoire by learning spells from scrolls. They can copy new Wizard class spells from Spell Scrolls by paying gold, making them the only class capable of learning spells in this manner. However, this ability is restricted to spells on the Wizard class spell list, preventing them from learning spells like Cure Wounds from spell scrolls.

1.3. Strategic Spell Selection for Limited Casters

For Sorcerers, Bards, Warlocks, and Rangers, strategic spell selection during level-ups is essential. These classes have limited spells known, making each choice impactful. Consider how spells synergize with your character’s abilities and your party’s composition.

1.4. Balancing Low and High-Level Spells

As casters level up and gain access to higher-level spells, it’s important to consider spells from lower levels as well. The number of available spells at high levels is smaller compared to low levels, and some low-level spells remain useful throughout the game.

Strategic Reassessment: Reassess previously overlooked low-level spells for their potential utility at higher levels.
Spell Slot Management: Evaluate the number of new high-level Spell Slots you receive and avoid selecting more high-level spells than you can cast.

Prioritize spells that offer versatility and utility, rather than simply choosing the highest-level spell available.

2. Mastering Spell Preparation in BG3

After taking a rest or leveling up, Wizards, Druids, Clerics, and Paladins engage in the process of spell preparation. They select a subset of spells from their pool of known spells and prepare them for actual casting.

Wizards: Wizards prepare spells by studying their spellbook, committing the arcane formulas and incantations to memory.
Druids: Druids prepare spells through meditation and attunement with the natural world, drawing upon the energies of the flora and fauna around them.
Clerics: Clerics prepare spells by praying to their deity, seeking guidance and empowerment to channel divine magic.
Paladins: Paladins prepare spells through reflection on their sacred oath, reaffirming their commitment to justice and righteousness.

In BG3, spell preparation is managed through the Spellbook tab of the character info menu, allowing players to create a personalized “menu” of spells they might want to cast that day.

2.1. Spell Preparation Limits

The number of spells a character can prepare is determined by their class level and primary spellcasting ability modifier.

Wizards, Druids, and Clerics: Can prepare a number of spells equal to their caster class level + their primary spellcasting ability modifier.
Paladins: Can prepare spells equal to half their caster class level + their primary spellcasting modifier.

Efficient spell preparation requires careful consideration of the challenges and opportunities the party is likely to face.

2.2. Always Prepared Spells

Bards, Warlocks, Rangers, and Sorcerers do not go through the process of preparing spells. Instead, all of their known spells are always prepared. This streamlined approach allows these classes to cast any of their known spells at any time, without the need for pre-selection.

The trade-off for this convenience is that they generally know fewer spells compared to classes that prepare spells.

3. Spells Known and Spells Prepared Caster List

Here’s a summary of how different caster classes handle spells known and spells prepared:

Class	Spells Known	Spells Prepared
Wizard	Limited number of spells known	Limited number of spells prepared
Sorcerer	Limited number of spells known	All known spells always prepared
Bard	Limited number of spells known	All known spells always prepared
Druid	Knows all class spells	Limited number of spells prepared
Cleric	Knows all class spells	Limited number of spells prepared
Warlock	Limited number of spells known	All known spells always prepared
Ranger	Limited number of spells known	All known spells always prepared
Paladin	Knows all class spells	Limited number of spells prepared

4. Understanding Spell Slots in BG3

Spell Slots represent the magical energy a caster has available to cast spells before needing to rest. Each caster class has a certain number of 1st Level Spell Slots, 2nd Level Spell Slots, 3rd Level Spell Slots, and so on, depending on their class level.

Full Casters: Classes like Wizards, Clerics, and Druids can get up to four spell slots for 1st level spells, but only one spell slot for 6th level spells.
Limited Casters: Classes like Paladins and Rangers have fewer spell slots overall, reflecting their hybrid nature.

Classes that don’t automatically know all of their class spells when leveling up, like Wizards, Sorcerers, Bards, Warlocks, and Rangers, must carefully select spells at higher levels to maximize their effectiveness with limited spell slots.

4.1. High-Level Spell Slot Management

Consider a 12th level Wizard who can know as many as four 6th level spells by default but only has a single 6th level spell slot. This means they can only prepare one of those spells at a time. Similarly, a 12th level Cleric automatically knows all six of their 6th level class spells but also only has a single 6th level spell slot.

Effective spell slot management involves prioritizing spells that offer the greatest impact and utility, while also considering the availability of lower-level spells that can be upcast for increased effectiveness.

4.2. Visualizing Spell Slots in BG3

In BG3, Spell Slots are represented as small check boxes on the Action Bar interface. When you cast a spell, one of your Spell Slot check boxes of the appropriate Spell Level loses its color and becomes white. This provides a clear visual representation of your remaining magical energy.

4.3. Accessing Available Spells

You can see all your available spells to cast by clicking on the Action or Bonus Action boxes. Alternatively, you can click on your 1st Level Spell Slot check boxes to see only your 1st Level spells, click the 2nd Level Spell Slot check boxes to see your 2nd level and lower spells, and so on.

4.4. Upcasting Spells

The Spell Slot check boxes make the Upcasting mechanic easy to use in game. Upcasting involves casting a lower-level spell using a higher-level spell slot, increasing its effectiveness.

5. Optimizing Your Spellcasting Strategy in BG3

To become a master spellcaster in BG3, consider the following strategies:

Know Your Class: Understand the unique spellcasting mechanics of your chosen class, including how they acquire spells, prepare spells, and manage spell slots.
Strategic Spell Selection: Carefully select spells that complement your character’s abilities and your party’s composition, prioritizing versatility and utility.
Efficient Spell Preparation: Prepare spells that are appropriate for the challenges you expect to face, considering both combat and exploration encounters.
Spell Slot Management: Manage your spell slots wisely, prioritizing high-impact spells and utilizing upcasting to maximize your magical potential.
Adapt to the Situation: Be flexible and adapt your spellcasting strategy to the specific circumstances of each encounter, considering enemy weaknesses and environmental factors.

By mastering these principles, you can unlock the full potential of your spellcaster and become a formidable force in BG3.

6. Advanced Spellcasting Techniques in BG3

Beyond the fundamentals, several advanced techniques can further enhance your spellcasting prowess:

Spell Synergies: Identify spells that synergize well with each other, creating powerful combinations that can devastate enemies or overcome challenging obstacles.

Environmental Interactions: Take advantage of environmental interactions, such as using spells to create difficult terrain or manipulate hazards.
Counterspelling: Master the art of counterspelling to disrupt enemy spellcasters and prevent them from unleashing devastating attacks.

6.1. Metamagic (Sorcerers)

Sorcerers gain access to Metamagic, allowing them to modify their spells in various ways, such as increasing their range, empowering their damage, or splitting them between multiple targets.

6.2. Eldritch Invocations (Warlocks)

Warlocks gain access to Eldritch Invocations, granting them unique abilities and spell modifications that enhance their combat prowess and utility.

6.3. Channel Divinity (Clerics and Paladins)

Clerics and Paladins gain access to Channel Divinity, allowing them to unleash powerful divine abilities that can turn the tide of battle or provide essential support to their allies.

7. Case Studies: Spellcasting in Action

To illustrate the principles discussed above, let’s examine a few case studies:
