The short answer is: No, Detect Magic cannot directly “see” an invisible creature. While Detect Magic can sense the presence of magic within its range, it doesn’t grant the ability to visually perceive the source. Think of it like smelling smoke; you know something is burning, but you can’t see the flames if they’re hidden behind a wall. You’ll sense the magical aura, but you won’t know where it’s coming from. A dedicated spell like See Invisibility is specifically required to visually perceive invisible creatures and objects.
Delving Deeper into Detect Magic and Invisibility
Detect Magic is a valuable tool for identifying magical auras and discerning the school of magic associated with visible objects or creatures. However, it’s essential to understand its limitations. The spell only allows you to sense the presence of magic; it doesn’t automatically reveal the nature, location, or source of that magic if it’s already hidden from sight. The key distinction is that Detect Magic tells you that something magical is there, while other spells are needed to reveal what and where.
Imagine a scenario: A rogue casts Invisibility and sneaks into a room. A wizard, suspecting foul play, casts Detect Magic. The wizard will sense magic within range, but won’t be able to pinpoint the rogue’s exact location. They would need to cast See Invisibility or use another ability that grants the power to see the unseen.
Therefore, Detect Magic is best used as a first step in identifying magical activity, prompting further investigation with more specialized spells or abilities to reveal hidden elements. Understanding the interplay between these spells is crucial for effective gameplay and strategic decision-making.
Frequently Asked Questions About Detect Magic and Invisibility
Here are 15 frequently asked questions to further clarify the capabilities and limitations of Detect Magic in relation to invisibility and other related magical effects:
1. If I sense magic with Detect Magic, will I know it’s an Invisibility spell?
No. Detect Magic reveals the presence of magic and, if you take an action to concentrate on a visible object or creature, its school of magic. Invisibility is typically an illusion or transmutation spell. Detect Magic might indicate the presence of either of those schools of magic, but it won’t tell you what specific spell is creating the effect. You’d need Identify or similar spells to determine the precise magical effect.
2. Does Detect Magic reveal invisible objects?
Detect Magic can detect the presence of magic radiating from an invisible object within range. However, you won’t be able to see the object itself. You will just know that there is magic in a general area. A spell like See Invisibility is required to visually perceive the object.
3. Can Detect Magic penetrate walls to detect invisible creatures?
Yes, Detect Magic can penetrate barriers to some extent. The spell description typically specifies that it can penetrate most barriers, but is blocked by 1 foot of stone, 1 inch of common metal, a thin sheet of lead, or 3 feet of wood or dirt. So, if an invisible creature is behind a thin wooden door, Detect Magic could potentially sense its magic.
4. If a creature is Greater Invisible, can See Invisibility still reveal it?
Yes, See Invisibility will detect Greater Invisibility unless there’s something else specifically countering it. Greater Invisibility simply enhances the base Invisibility spell, and See Invisibility provides the ability to see through both.
5. Can Detect Magic reveal a Scrying sensor?
Yes, the sensor created by the Scrying spell can be sensed with Detect Magic. The sensor itself is an invisible magical effect, so while you won’t be able to see the sensor, Detect Magic will indicate its presence.
6. Can Detect Magic reveal illusions besides Invisibility?
By strict rules, Detect Magic can sense the presence of illusions of all kinds. However, it won’t reveal that they are illusions. You’ll only know there is a magical effect in your vicinity. Determining that the magic is an illusion requires further investigation and possibly another spell.
7. Does Detect Magic reveal a creature that is naturally invisible, rather than magically invisible?
No, Detect Magic only detects the presence of magic. If a creature has a natural ability to turn invisible (without magic), Detect Magic will not detect it.
8. Can Detect Magic reveal a caster concentrating on a spell that creates invisibility on another target?
No, Detect Magic doesn’t detect spellcasters concentrating on spells. It detects the presence of existing magic. The Invisibility spell cast on the target is what Detect Magic would detect, not the concentration of the caster.
9. Can I cast Identify on an invisible person after sensing magic with Detect Magic?
Yes. You can cast Identify on a person if the rules of your game allow. Because they are Invisible, you are able to cast Identify on the person once you know their position.
10. If a character is wearing a magic ring of invisibility, will Detect Magic reveal the magic?
Yes, Detect Magic will detect the magic radiating from the ring. Using your action, you will see a faint aura around the magic ring on the invisible character, and learn its school of magic, if any. You won’t be able to see the character unless you have other means of seeing invisible creatures.
11. Can Detect Magic see inside a Bag of Holding to detect invisible objects?
No, Detect Magic cannot see inside a Bag of Holding or other extradimensional spaces. These spaces exist on a separate plane of existence and are therefore beyond the range of the spell.
12. Does Detect Magic reveal undead creatures made invisible?
Detect Magic will detect the Invisibility spell affecting the undead creature. It will not identify the target as undead. Detect Magic does not generally detect undead creatures unless they are sustained by an ongoing magical effect. The lingering negative energy is considered a natural state.
13. How does True Sight compare to Detect Magic in revealing invisibility?
True Sight is far superior to Detect Magic in this regard. True Sight allows you to see things as they truly are, negating illusions and revealing invisible creatures and objects. Detect Magic only senses the presence of magic; it doesn’t grant visual perception. True Sight removes the need for interpretation by showing the reality of the situation. This also removes the need to deduce that an object is invisibile or not.
14. Does Detect Magic reveal Unseen Servants?
An Unseen Servant is not invisible in the traditional sense; it is shapeless and imperceptible, not rendered invisible by magic. Therefore, Detect Magic wouldn’t detect it since it’s not the result of a lasting magical effect, or the subject of any illusion.
15. Can Detect Magic sense a spell being cast that will result in invisibility?
No, Detect Magic cannot detect spells being cast. It only detects magic that is already in effect. It relies on an existing magical presence to be detectable. If a spellcaster starts casting Invisibility, Detect Magic won’t register anything until the spell is fully cast and the target becomes invisible.
