Notes

• Also granted to  Warlocks who choose the Eldritch Invocation  Armour of Shadows at level 2+. This version of the spell can only target self, and doesn't expend Spell Slots.
• You can cast this spell on all party members then dismiss the caster from the party and this buff will persist.
  • If cast by a  Wizard, this spell must remain Prepared by the party member who cast it; removing Mage Armour from the caster's Prepared Spells list will immediately remove the buff from all party members whom the caster applied it to. If applied by using (not scribing) a scroll, the caster does not need to keep this spell Prepared to maintain the buff.
• If a party member who has Mage Armour equips a piece of Armour, the buff will be removed. Mage Armour will not be reapplied when unequipping that Armour; it will need to be cast on them once more.

• The normal base  Armour Class is 10 + Dexterity modifier, while this changes it to 13 + Dexterity Modifier.
  • You will still get bonuses from other sources that don't change your base armour class like +1 AC robes, Bracers of Defence,  Shield of Faith, etc.
• Gloves and Helmets marked as  Light,  Medium or  Heavy Armour count as armour, and will prevent Mage Armour from working.
• Mage Armour works while wearing a  Shield.
•  Mage Armour,  Draconic Resilience,  Unarmoured Defence (Barbarian),  Unarmoured Defence (Monk) and  Barkskin all change your base armour class and therefore does not stack.
  • If you have multiple of these you will only get the benefit of the one that gives the most  Armour Class.
• Mage Armour can work while in  Wild Shape as long as you have no armour equipped in any slot before transforming.
  • This effect only works on forms with a base  Armour Class of less than 13.
• Mage Armour does not count as wearing armour for things like  Unarmoured Movement,  Become the Bulwark and  Defence.

• The incantation for Mage Armour is Mactē Virtutē, the Latin command "honour with virtue!"
