The Wizard is one of the most iconic and versatile spellcasters in Dungeons & Dragons 5th Edition, offering a deep toolkit for exploration, control, and burst damage. This guide explains how Wizard works at the table, details class features and key mechanics, and provides actionable advice for building and playing a Wizard effectively. Whether you are new to the class or refining a long-running arcane mind, you will find concrete guidance to make your spells count.
Core Class Features
At the heart of the Wizard is a simple structure: you prepare a limited number of spells each day, then use spell slots to cast them at higher levels as needed. Key traits include:
- Spellcasting based on Intelligence, making it the most important ability for attack rolls, DCs, and spell save DCs.
- Arcane Recovery, allowing you to regain some spell slots during a short rest.
- An expanded spellbook, where you can copy and customize spells as you level up.
Spellcasting and Spell Save DC
Your spell save DC is calculated as 8 + your proficiency bonus + your Intelligence modifier, while your spell attack modifier is spellcasting ability modifier + proficiency bonus. As you gain levels, increasing your Intelligence and proficiency bonus will directly improve your chance to hit and your DCs. This makes consistent ability improvement one of the highest priorities for the class.
Spellbook and Ritual Casting
Wizard prepares a number of spells from your spellbook each day, limited by your level and Intelligence modifier. Any Wizard spell you copy into your book can be prepared and cast, and many spells can be cast as rituals if they have the ritual tag and you have them prepared. Ritual casting is powerful for non-comoutine problem solving, provided you manage limited spell slots carefully.
Understanding Spell Slots and Preparation
Spell slots determine how many times you can cast your spells of each level, and they refresh after a long rest. Preparation lets you choose which spells to make available from your spellbook. Choosing the right prepared spells is one of the most impactful tactical decisions a Wizard makes. Below is an example table of slot progression and typical spell allotments for a level 5 Wizard prepared from a 10-spell spellbook.
| Wizard Level | Spell Slots (1st/2nd/3rd/4th) | Typical Spells Prepared | Key Source |

| 5 | 4/3/2/2 | 4–5 prepared, including key utility and damage spells | Player's Handbook |
| 10 | 4/4/3/3 | 6–8 prepared, balancing damage, control, and defense | Player's Handbook |
| 17 | 4/4/4/3 | 8–10 prepared, optimized around role, enemy types, and campaign | Xanathar's Guide to Everything |
