The  spell description states:     For the duration, you sense the presence of magic within 30 feet of you. If you sense magic in this way, you can use your action to see a faint aura around any visible creature or object in the area that bears magic, and you learn its school of magic, if any.   In  question it is said that detect magic can reveal the presence of a sorcerer. What about other classes, like clerics (whose magic has a divine origin), or wizards?

Inspired by a recent question about discerning divine and arcane spellcasters, of like to hear the case for and against detecting spellcasters of either style with .  I think you can detect whether someone has prepared spells, based on this language:     For the duration, you sense the presence of magic within 30 feet of you. If you sense magic in this way, you can use your action to see a faint aura around any visible creature or object in the area that bears magic, and you learn its school of magic, if any. (emphasis mine)   Preparing spells is described as having the spell "fixed in mind" (). I'd argue that qualifies as bearing magic, and opens the door to using detect magic to identify spellcasters with currently prepared spells. What do you think?

Creatures with Truesight, have a number of benefits, one of which is that they     automatically detect visual illusions and succeed on saving throws   against them   How do you determine if a spell creates a visual illusion? Is it as simple as "If the illusion creates something that the target can see, it's visual" or is there a more specific rule?  For some context, this came up into play in our last session where a Wizard PC cast Mental Prison on an enemy with Truesight an we weren't exactly sure how to rule it at the time and decided to research it after the session was over.

Several wands and other magic items in the DMG cite &quot;spellcaster&quot; as an attunement requirement, specifically &quot;requires attunement by a spellcaster&quot; while others list multiple spellcasting classes (e.g., a Staff of Fire &quot;requires attunement by a druid, sorcerer, warlock, or wizard&quot; p. 201). However, all the DMG states in this regard is:  Some magic items require a creature to form a bond with them before their magical properties can be used. This bond is called attunement, and certain items have a prerequisite for it. If the prerequisite is a class, a creature must be a member of that class to attune to the item.¹ (If the class is a spellcasting class, a monster qualifies if that monster has spell slots and uses that class's spell list. [emphasis and footnote added] (p. 136)  The language of the Mage Slayer feat describes a spellcaster as a creature casting or concentrating on a spell.  You have practiced techniques useful in melee combat against spellcasters [...] When a creature within 5 feet of you casts a spell ... [and] When you damage a creature that is concentrating on a spell ... (PHB, p. 168)  From the above, it does not appear that &quot;spellcaster&quot; would necessarily be considered a class or group of classes, so Are characters that can cast spells, regardless of their class(es), considered spellcasters? Or, put another way, Does &quot;spellcaster&quot; (as an attunement prerequisite) mean any creature who can cast a spell or does it mean all classes with the Spellcasting feature? I can think of five particular cases—innate abilities, two subclasses and two feats: High Elves know one wizard cantrip (0-level spell) of their choice. Drow can cast the dancing lights cantrip, 1st-level spell faerie fire and 2nd-level spell darkness. Forest Gnomes know the minor illusion cantrip, and Tieflings can cast the thaumaturgy cantrip and 2nd-level spells hellish rebuke and darkness. Also, many monsters have innate spellcasting abilities, which would trigger the Mage Slayer feat. Starting at 3rd level, both the Eldritch Knight (Fighter Martial Archetype) and Arcane Trickster (Roguish Archetype) gain the ability to cast wizard spells and gain wizard spell slots (potentially) up to 4th-level spells. PHB, pp. 75 &amp; 98. The latter's 17th-level Spell Thief feature also states &quot;you gain the ability to magically steal the knowledge of how to cast a spell from another spellcaster,&quot; (Ibid.) which strongly implies that (at least) the Arcane Trickster is a spellcaster, although neither subclass is specifically listed as a prerequisite for any magic item in the DMG. Eldritch Knight and Arcane Trickster are also found under Multiclassing, Spell Slots in the PHB:  You determine your available spell slots by adding together all your levels in the bard, cleric, druid, sorcerer, and wizard classes, half your levels (rounded down) in the paladin and ranger classes, and a third of your fighter or rogue levels (rounded down) if you have the Eldritch Knight or the Arcane Trickster feature. (p. 164)  With the Ritual Caster feat, a character chooses a spellcasting class (except paladin or ranger) and gains the ability to cast spells of that class with the ritual tag as rituals. The character immediately gets two 1st-level ritual spells of that class and has the potential to (eventually) learn all of the ritual spells of the chosen class. PHB, p. 169. With the Magic Initiate feat, a character chooses a particular spellcasting class (except paladin or ranger) and immediately learns two cantrips and one 1st-level spell from the class with no further advancement. PHB, p. 168. By definition, it seems all of the above would qualify as spellcasters, but I feel spellcaster typically (or maybe traditionally) refers to bard, cleric, druid, paladin, ranger, sorcerer, warlock and wizard.   I believe an exception would be a 13th level or higher Thief (Roguish Archetype) due to the Use Magic Device feature. PHB, p. 97.

This came up in game tonight.   is a spell with Range: Self (15-foot cube).  The description reads:     A wave of thunderous force sweeps out from you.  Each creature in a 15-foot cube originating from you...   Players Handbook, 282-283  Does the area of effect center on the caster (extending 7.5 feet in each direction), or does it begin from the caster, and extend in the direction desired (for a full 15 feet)?

Last session, one of my players said he wanted to cast minor illusion - creating a high-pitched screaming noise - within the inner ear of a Worg. I ruled it was permissible, got the Worg to take a Constitution check to not be alarmed, and it succeeded, remaining unperturbed.  But I've since been thinking - could you cast minor illusion in such a small, specific location within combat? Could I perhaps rule that the PC should take a penalty of some sort? Is a Con check appropriate? What would the effects of such below-the-belt tactics be if they succeed?

get the Eyes of the Dark feature (XGtE, p. 51):     When you reach 3rd level in this class you learn the darkness spell [...] If you cast it with sorcery points, you can see through the darkness created by the spell.   Does this mean that if a Shadow Sorcerer casts darkness using sorcery points and then moves into a different area of magical darkness (not the one s/he created), the Sorcerer would not be able to see?  Or does the ability mean that the Sorcerer would possess the ability to see through the magical darkness created by the darkness spell in general (provided they were maintaining their own casting of the spell)?

So, say you are a wizard 15/warlock 2. You have the Lance of Lethargy invocation, which pushes an enemy you target with eldritch blast and hit back 10 feet. Say you put a demiplane entrance ~5 feet behind the enemy you target with it. When you hit, you throw the enemy in. Before all this, you had put a Glyph of Warding in there on one of the surfaces. What would be the limit to the trigger for this? Would it be forced to be touch or proximity, or could you base it off something like hostility towards the caster?      ... When you cast this spell, you inscribe a glyph that later unleashes a magical effect ... You decide what triggers the glyph when you cast the spell. For glyphs inscribed on a surface, the most typical triggers include touching or standing on the glyph, ... (PHB 245)   The key word here is "typical". Based on Google's definition, the informal definition of "typical" is     showing the characteristics expected of or popularly associated with a particular person, situation, or thing.   This means, if my assumption is true, that the triggers in the PHB are only the most common ones. Other than the one about being forcibly at maximum 10 feet in diameter in the PHB, I cannot see a limit. Though I probably should assume this would all be DM discretion, (and I know that I sound like a broken record here) but could the trigger be hostility toward the caster, or something else, like being a specific race, gender, from a specific place, etc., or would it be forced to being something from the PHB?

Invisibility reads: "A creature you touch becomes invisible until the spell ends..."  Greater Invisibility says: "You or a creature you touch becomes invisible until the spell ends..."  By omission, does this suggest that one cannot use Invisibility on oneself?

In D&amp;D 5e, the description of hiding (PHB p177) says an invisible creature needs to stay quiet and otherwise avoid leaving signs of its passing, while the "invisible" condition (p291) says the creature's location can be determined by any noise it makes. This seems straightforward: even a blinded creature can pinpoint the location of anything on the battlefield that isn't tiptoeing/holding its breath.   However, the Ranger's "Feral Senses" ability (p92) grants awareness of the locations of invisible creatures within 30 feet, provided the creatures aren't hiding and that the Ranger can both hear and see. I realize the ability also removes the disadvantage to attack rolls against invisible creatures, but the wording and limitations seem to imply that awareness of the location of an invisible, unhidden creature isn't a given.  I realize the hidden vs invisible question has , but I'm hoping someone can explain what changes for a Ranger when she hits 18th level. Is there a scenario where a creature who can see and hear would not be aware of the location of unhidden, invisible creatures within 30 feet? Or is this just the equivalent of giving a fighter the ability to add half of their proficiency bonus to attacks with simple weapons for which they don't already have proficiency?

Well, as the trace is present upon an underage Wizard before he comes of age, hence the Ministry being able to detect underage magic immediately whenever the underage Wizard does it, I still don't quite understand the following situations.  (Is it traceable by location or by person?)  When Dobby did the Hover Charm (Year 2), the Ministry couldn't differentiate whether it was indeed Dobby or Harry Potter who performed it. Suggesting the Ministry detect some kind of magic at a particular address they have on record as being resident to an underage wizard?  However, when Arthur Weasley visited Harry Potter at Privet Drive (Year 4), he did a lot of magic, including magically dodging the teacups Mr. Dursley was throwing as him, and as well as performing an anti-Engorgment charm to return Dudley's tongue to a normal size. So how come did the Ministry differentiate who actually performed magic?  Moreover, at The Burrow, what happens if an underage Harry or Ron performs magic? Can't simply the elders say they performed magic instead?  Update: After reading two answers below I'm still confused. If magic is location based, Tonks, Madeye and Dumbledore all do a lot of magic at Privet Drive and Harry is never caught. Additionally, can't Harry do magic at The Burrow and Mrs. Weasley simply say she did it instead. Whereas if Magic is person based, obviously it isn't because they could differentiate that Dobby performed the magic and not Harry.

I had a disagreement with one of my groups recently: They believe that the  spell is the only way to identify a magic item, while I believe a high enough Intelligence (Arcana) check is able to do the same.   What I came here to ask is: What are all the possible ways to identify a magic item?

Is it true that not even the person/creature/thing doing the initial action that starts a combat is able to use a full-round action?  According to all sources I can find, the initial attack already is part of the surprise round, so you're only entitled to a move action or standard action; but that leads to an (in my opinion) absurd scenario, so I just wanted to be sure whether there is something I'm missing:  Let's say sorcerer A is hiding in the bushes, 1HP left, waiting to finish sorcerer B (1HP left) off with magic missiles before B does the same to A. Then he suddenly spots sorcerer B - but sadly, he's some feet out of range. Now sorcerer A wants to use metamagic to double his magic missiles range and fire that on sorcerer B ... but now his magic missile takes a full-round action to cast, so sorcerer A cannot surprise sorcerer B with it anymore.  Is this interpretation right RAW-wise or am I missing something?

got me thinking about the mechanics of the Magic Initiate feat when you have class levels in the class into which you were inducted.    Among the classes you can pick with this feat are the Bard, Sorcerer, and Warlock, which know a limited number of spells and all have the same statement under Spells Known.     Additionally, when you gain a level in this class, you can choose one of the [class] spells you know and replace it with another spell from the [class] spell list , which must also be of a level for which you have spell slots.   The term "learning" is used both to describe new spells acquired on level-up and the spell acquired through the feat. This would seem to indicate your Magic Initiate spell counts among the spells you know, and is thus eligible for retraining if you learned it as a spell of your class.  An odd change in wording occurs during the Magic Initiate feat description (emphasis mine):     In addition, choose one 1st-level spell from the same list. You learn that spell and can cast it at its lowest level.   This generalization in describing the learned spell's level seems to imply that there exists a scenario where it would not be appropriate to restrict the spell to being cast as a 1st-level spell.  Could one of the charisma casters retrain Magic Initiate into a higher level spell, which they could then cast once per long rest without using a slot?  This would turn an otherwise unexciting feat into, effectively, a Mystic Arcanum for Bards and Sorcerers. This seems too powerful to be intentional,  but the feat description appears to have gone out of its way to permit it.

The  spell has a duration of instantaneous, which implies that the familiar itself is not an ongoing magical effect. However, the spell provides a number of ongoing features that are definitely supernatural:    The familiar disappears when it drops to 0 HP. The wizard can temporarily or permanently dismiss the familiar. The wizard can communicate with the familiar telepathically. The wizard can observe through the familiar's eyes and ears. The familiar can deliver touch spells on behalf of the wizard.   Which of these features are considered magical? For example, would any of them show up to a detect magic spell or be suppressed by an antimagic field? In addition, is my assumption above correct that the familiar itself is not considered magical?

I'm curious of how illusions would affect spells or abilities that require a target to be looking at something. A good example of this would be Medusa's Petrifying Gaze which has the following effect:  Petrifying Gaze: When a creature that can see the medusa's eyes starts its turn within 30 feet of the medusa, the medusa can force it to make a DC 14 Constitution saving throw if the medusa isn't incapacitated and can see the creature. If the saving throw fails by 5 or more, the creature is instantly petrified. [...]  So if someone were to cast Minor Illusion to put a bag over Medusa's head, would other player/creatures who do not realize that the bag is an illusion be affected by the gaze if they were looking in the direction of it? Does the illusion block the effect?

My understanding is that when a spell is known or prepared via one of your class features, or if you cast it via a class feature, it's considered a "class spell" (sorcerer spell, cleric spell, etc.) for you. If you cast it via some method outside your class (items, etc.), it isn't considered a spell from your class.  For clarity, some class features care about whether or not a spell is a 'class' spell (emphasis mine):    Wild Magic Surge for Wild Magic sorcerers can only trigger "[...] immediately after you cast a sorcerer spell [...]". Overchannel for School of Evocation wizards can only be used "when you cast a wizard spell [...]" Empowered Evocation for School of Evocation wizards can also only be used on "[...] any wizard evocation spell you cast". Rod of the pact keeper gives a bonus "[...] to the saving throw DCs of your warlock spells".   Contrast with a feature like Blessed Healer for Life Domain clerics that just use the language of "When you cast a spell [...]", and you'll see why I believe there's an important distinction as to whether or not a spell instance is a 'class' spell.  However, comments on  made me question where my understanding of what makes a spell instance a 'class' spell comes from, and I'm not sure of a concise spot that explains it. What are the rules that govern what is or is not considered a class spell when cast?   Of particular concern is whether or not a spell is, in all instances, a class spell once you've obtained it from your class. For example, if you were a wizard that had magic missile both prepared and in your spellbook, would any instance of magic missile you cast be considered a wizard spell, even if it was cast by way of, say, a wand of magic missile?

Assuming a target of a Pathfinder spell did not see/hear/notice a caster casting the spell, do they know/feel they were targeted?  Is it relevant if the spell worked or not, if a save was involved (either successful nor not)? Does it depend on the spell?  Example: A cleric casts detect evil through a door. What do the NPCs on the other side know now?
