In Dungeons & Dragons, wizards use Intelligence for spellcasting—not Wisdom. Wisdom still matters for abilities such as Perception and Insight, and it is one of the wizard’s saving-throw proficiencies in the 2024 rules.
Which ability does a D&D wizard use to cast spells?
Intelligence is the wizard’s spellcasting ability in both the 2014 rules and the 2024 rules reference. The 2024 System Reference Document 5.2 names Intelligence as the wizard’s primary ability. The 2014 Basic Rules explain that wizard spells rely on dedicated study and memorization.
Under the 2014 rules, Intelligence contributes to spell attacks and spell save DCs. The formulas are:
- Spell save DC: 8 + proficiency bonus + Intelligence modifier.
- Spell attack modifier: proficiency bonus + Intelligence modifier.
These formulas are from the 2014 rules; the 2024 reference identifies Intelligence as primary but should not be assigned the 2014 spell-preparation formula.

What does Wisdom do for a wizard?
Wisdom supports awareness and intuition rather than wizard spellcasting. In the 2014 rules, it is used for checks such as Perception, which can help notice danger, and Insight, which can help interpret another creature’s intentions. The 2024 SRD also lists Wisdom as one of the wizard’s saving-throw proficiencies, alongside Intelligence.
Intelligence and Wisdom are therefore useful in different ways: Intelligence powers wizard spells, while Wisdom can help with noticing, interpreting, and resisting certain effects. The rules do not present them as interchangeable spellcasting options.

How do the 2014 and 2024 rules differ?
| Rules reference | Wizard spellcasting ability | Other relevant detail |
|---|---|---|
| 2014 Basic Rules | Intelligence | Prepared spells equal wizard level + Intelligence modifier, with a minimum of one. |
| 2024 System Reference Document 5.2 | Intelligence is the primary ability. | Saving-throw proficiencies are Intelligence and Wisdom. |
The preparation count shown for 2014 is specific to that rules version. Do not use it as the 2024 preparation rule. The 2024 entry is in the official System Reference Document 5.2, while the 2014 spellcasting and preparation details appear in the 2014 wizard class rules.
What is the practical ability-score priority?
If you are deciding which ability supports your wizard’s spells, prioritize Intelligence. Wisdom can still be valuable for the character’s awareness, intuition, and relevant saving throws, but raising Wisdom does not replace Intelligence as the wizard’s spellcasting ability under these rules.

In the 2014 rules, Intelligence checks draw on logic, education, memory, or deduction; Wisdom checks reflect perceptiveness and intuition. The 2014 ability-score rules list Arcana and Investigation among Intelligence-linked skills, and Perception and Insight among Wisdom-linked skills. These are general ability roles, not a claim that every check must use a fixed ability-and-skill pairing.

No. This answer concerns Dungeons & Dragons, specifically the 2014 Basic Rules and the 2024 System Reference Document 5.2. Other games and fictional settings can assign different abilities or mechanics to a wizard.
