Can detect magic see invisibility 5e?
In simple words, Detect magic can not see Invisibility in 5e. You can’t see the animal’s aura. You can still detect whether there’s magic within 30 ft of you, including magical things he might be carrying out. However, you can not determine the nature of the products, in the text of Detect Magic 5e.
For the duration, you sense the presence of magic within 30 feet of you. Suppose you feel magic in this manner. You can use your actions to see a faint aura about any observable creature or object in the area that conveys charm. You learn its college of magic if any. You can’t pinpoint an invisible animal or object’s place with Detect Magic alone.
First, as Miniman points out, the evil Mage should not be permitted to maintain Concentration on both Fly and Greater Invisibility at the same time.
Secondly, Jeremy Crawford, on Twitter, ruled the following. While you detect the presence of a magically invisible creature within 30′ you can’t see its aura unless it’s possible to see the monster.
Detect Magic 5e
Detect magic allows you to see an aura only around a visible creature or thing, not around an illusion. But you can sense the magic.
So if the Mage had only cast Greater Invisibility, a PC which casts Detect Magic 5e would know there is some magic in 30′ but not see an aura to the Mage (or his wand). The sensation of mysticism could be brought on by anything, including PC magic items or continuing spells. Therefore this might not be helpful. The PC would not know which square the Mage was from Detect Magic because he wouldn’t see an aura.
The Mage should roll a Stealth test (conceal as an Action) if he doesn’t want the PCs to understand where he is. Every time he strikes or makes substantial noise. For example, in spellcasting, he needs to spend a new Action to conceal. When a PC’s passive perception beats/equals the Mage’s Stealth test, the PC knows what square the Mage is in and may use an attack or spell that does not require sight (most non-AoEs spells with saves need that the visible target. Attacks (and spells with attacks) will have drawback but spells with saving throws won’t. A PC may also spend an action to roll an active perception check to try to beat the Mage’s Stealth (if their passive was not significant enough).
Each time the Mage takes some damage, they will have to make a Concentration check to stay invisible. The PCs will have to rely on a blend of multiple hits to force minimum Concentration saves. A few considerable damages (>= 22 damage) strikes to induce a Concentration save using a greater DC.

A PC which knows which square the Mage is in will Attack with a weapon at a disadvantage. Each attack that strikes will lead to another check. Cast an attack spell such as Eldritch Blast or Shocking Grasp or Scorching Ray with Disadvantage. Each attack that hits will lead to another Concentration check.
- Twist Fireball at the Mage’s square foot. The rescue is rolled usually.
- Cast Acid Splash normally (it aims at “one creature within range”).
The PC cannot:
A PC can probably figure out which square to a goal by watching where their allies are targeting or get advice if they could not figure it out.
Can Blindsight see invisibility 5e?
It can see whatever that comes in its radius. All of the kinds mentioned above of sight penetrate Invisibility. See Invisibility in 5E is a little weirder than it was. From the condition list:
An invisible creature is not possible to see without the help of magic or a unique sense. For the role of Hiding, the beast is greatly obscured. The animal’s location could be detected by any sound it makes or some other tracks it leaves. Attack rolls against the creature possess drawback, and the monster’s Attack rolls have an edge.
5e way of handling see Invisibility
3.5E had a much more explicit rule when dealing with stuff that’s imperceptible. However, the 5E ones had been left intentionally vague. You may handle it in a 3.5E way mixed with the new 5E way:
The invisible creature gets a Stealth check (usually with advantage). The creature hoping to detect it actively will get a Perception check. If the animal is not actively searching, they may get a passive Perception chance to “catch a flicker at the corner of the eye” or something like this. Even with the victory, they may know the creature is from the general area. If they succeeded (or the invisible creature messed up its Stealth check), they might see the square the monster is in. However, the beast remains invisible. Treat it heavily obscured so can’t be targeted by spells requiring visibility. It may nevertheless Hide, and creatures seeking to strike it will have the disadvantage.
The activity breakdown supposes that you are not in turns (combat has not started); if you are in the battle, keep in mind Hiding is a routine activity. If the invisible creature was detected, it could move then make use of the Hide action to begin the process all over again.
