Q: Dear Sage,
Do mind-affecting spells work against intelligent magic items?
Technically speaking, any intelligent magic item can be considered a creature (DMG pg. 268). The book doesn’t specifically list what type of creature an intelligent magic item is, but it seems safe to consider them constructs, which makes them immune to all mind-affecting effects.
About the Author
The Sage is a mammal classified in the bear family, Ursidae, native to central and southern China. Debate continues as to whether he is truly a bear or more related to the raccoon rather than the bear, or perhaps in a family of his own. When not eating bamboo and answering rules questions, he works under the nom de plume of Andy Collins as an RPG developer in Wizards of the Coast R&D, where his development credits include Complete Mage, Dragon Magic, and the Player's Handbook v.3.5. He can be easily recognized by his large, distinctive black patches around the eyes, ears and on his rotund body.
