Can Detect Magic Go Through Walls?
Detect Magic is a fascinating spell in the world of Dungeons & Dragons, allowing casters to sense the presence of magic within a certain radius. But, can it penetrate solid barriers like walls? In this article, we’ll dive into the intricacies of Detect Magic and explore whether it can go through walls.
The Basics of Detect Magic
Before we dive into the specifics of Detect Magic’s ability to penetrate walls, let’s quickly review the spell’s mechanics. Detect Magic is a 1st-level divination spell that allows the caster to sense the presence of magic within 30 feet of them. The spell reveals the location, strength, and duration of magical auras, as well as the school of magic they belong to.
The Rules on Penetration
According to the official rules, Detect Magic can penetrate most barriers, but there are some exceptions. Stone with a thickness of 1 foot or more, common metal with a thickness of 1 inch or more, thin sheet of lead, 3 feet of wood or dirt, and magical barriers can all block the spell’s effects.
Wall Thickness
When it comes to wall thickness, Detect Magic can penetrate walls of up to 1 foot thick. This means that a 1-foot thick stone wall, for example, would not block the spell’s effects. However, a 2-foot thick stone wall would be able to block the spell, as it exceeds the 1-foot threshold.
Material Types
The type of material used in the wall can also affect the spell’s penetration. Stone, wood, and dirt can all be penetrated by Detect Magic, while common metal and magical barriers can block the spell. Lead, in particular, is a unique case, as a thin sheet of lead can block the spell’s effects.
Exceptions
There are some exceptions to the rules on penetration. Extradimensional spaces, such as those found in Bag of Holding or Portable Hole, are not detectable by Detect Magic, even if they are filled with magical auras. Constructs, including golems, are also not detectable by the spell, unless they are the result of an ongoing spell, such as Summon Monster.
