Robe of the Archmagi Guide: The Best Armor for Wizards?

Last Updated on November 5, 2023

Robe of the Archmagi 

Wondrous Item, legendary (requires attunement by a Sorcerer, Warlock, or Wizard)

This elegant garment is made from exquisite cloth of white, gray, or black and adorned with silvery runes. The robe’s color corresponds to the alignment for which the item was created.

A white robe was made for good, gray for neutral, and black for evil. You can’t attune to a robe of the archmagi that doesn’t correspond to your alignment. You gain these benefits while wearing the robe:

You gain these benefits while wearing the robe:

  • If you aren’t wearing armor, your base Armor Class is 15 + your Dexterity modifier.
  • You have advantage on saving throws against spells and other magical effects.
  • Your Spell Save DC and Spell Attack Bonus each increase by 2.

Cost:  We estimate the Robes of the Archmagi could cost in the vicinity of 40,000 gold pieces. That’s assuming you can find someone willing to sell one, of course. 

What Are Robes of the Archmagi? 

The Robes of the Archmagi are a legendary wondrous item that grants the wearer an increased Armor Class, advantage on saving throws against spells and other magical effects, and a +2 bonus to their Spell Save DC and Spell Attack Bonus. 

In order to attune to the Robes of the Archmagi, you must have at least one level in either the Wizard, Warlock, or Sorcerer class. Also, your alignment must in some way match the robe’s color. 

  • White: Lawful Good, Neutral Good, Chaotic Good 
  • Gray: Neutral Good, True Neutral, Neutral Evil 
  • Black: Lawful Evil, Neutral Evil, Chaotic Evil 

If your alignment changes while attuned to the robe and your new alignment no longer matches the color of your Robes of the Archmagi, your attunement ends. 

If your alignment still matches the robes but in a different way (changing from Lawful Good to Chaotic Good, or from Neutral Good to Neutral Evil, for example), you remain attuned to them. 

Are Robes of the Archmagi a Good Item? 

The Robes of the Magi are an undeniably powerful magic item, especially since they provide a huge survivability increase for what are arguably the three least survivable classes in the game.

Improving Wizards’, Warlocks’, and Sorcerers’ ability to resist magical effects and improving their actual Armor Class is hugely important at higher levels where enemies are dishing out huge amounts of damage. 

That being said, if you have low Dexterity it’s only a +2 AC increase over Mage Armor — a 1st-level spell 

The real meat of this item is the +2 bonus to Spell Save DC and Spell Attack Bonus. This stat is impactful to any caster.

At the very highest tiers of play where your characters can expect to be fighting demigods, tarrasques, and demon lords, every little bit helps.  

That being said, there are other legendary items that grant more powerful buffs and still more items (at other rarities) that provide more interesting active abilities. 

I can appreciate the simplicity of three passive buffs to a high-level spellcaster.

Do Robes of the Archmagi and Mage Armor stack?

No. Both the Robes of the Archmagi and Mage Armor reset your base Armor Class (to 15 and 13, respectively), which is then modified by your Dexterity. Both can’t work at once, and therefore, the higher result will cancel out the lower one. 

Can You Change the Alignment of Robes of the Archmagi? 

Not easily. There’s no specific way to change the alignment of Robes of the Archmagi as it is set at the item’s creation. However, you might argue that any magical effect (a Wish spell, for example) that could forcibly change a character’s alignment could also be used to alter the alignment of a set of Robes of the Archmagi.
