When you cast this spell, you inscribe a glyph that later unleashes a magical effect. You inscribe it either on a surface (such as a table or a section of floor or wall) or within an object that can be closed (such as a book, a scroll, or a treasure chest) to conceal the glyph. The glyph can cover an area no larger than 10 feet in diameter. If the surface or object is moved more than 10 feet from where you cast this spell, the glyph is broken, and the spell ends without being triggered.
The glyph is nearly invisible and requires a successful Intelligence (Investigation) check against your spell save DC to be found.
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, removing another object covering the glyph, approaching within a certain distance of the glyph, or manipulating the object on which the glyph is inscribed. For glyphs inscribed within an object, the most common triggers include opening that object, approaching within a certain distance of the object, or seeing or reading the glyph. Once a glyph is triggered, this spell ends.
You can further refine the trigger so the spell activates only under certain circumstances or according to physical characteristics (such as height or weight), creature kind (for example, the ward could be set to affect aberrations or drow), or alignment. You can also set conditions for creatures that don’t trigger the glyph, such as those who say a certain password.
When you inscribe the glyph, choose explosive runes or a spell glyph.
Explosive Runes. When triggered, the glyph erupts with magical energy in a 20-foot-radius sphere centered on the glyph. The sphere spreads around corners. Each creature in the area must make a Dexterity saving throw. A creature takes 5d8 acid, cold, fire, lightning, or thunder damage on a failed saving throw (your choice when you create the glyph), or half as much damage on a successful one.
Spell Glyph. You can store a prepared spell of 3rd level or lower in the glyph by casting it as part of creating the glyph. The spell must target a single creature or an area. The spell being stored has no immediate effect when cast in this way. When the glyph is triggered, the stored spell is cast. If the spell has a target, it targets the creature that triggered the glyph. If the spell affects an area, the area is centered on that creature. If the spell summons hostile creatures or creates harmful objects or traps, they appear as close as possible to the intruder and attack it. If the spell requires concentration, it lasts until the end of its full duration.
At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage of an explosive runes glyph increases by 1d8 for each slot level above 3rd. If you create a spell glyph, you can store any spell of up to the same level as the slot you use for the glyph of warding.

make a nuke. Take a one hundred page book, cast this on the front and back of each page, and If you can, store fireball on it. Set the trigger to a phrase. Cast magic mouth on the book or near it, and make it say the phrase when a hostile NPC gets within say, 10 feet.
Bam. Take the spells damage and multiply it by the number of pages, plus the wards, if made to do damage, too.

If you had a lenient DM, you put the glyph in/on a book, set the trigger to "whenever a creature walks within 10 ft of the glyph" and have stored catapult in the glyph. Have catapult fling the book at the person who triggered the glyph. Technically does not target a creature, so RAW this wouldn't work, but I think it would be fun. Get a library of similarly enchanted books and you have a very aggressive library.
note: the last suggestion is very expensive, ao you may wish to use wish for the casting of this spell if possible.
Question. If we cast this inside a bag of holding (assuming you can breath for the 1 hour casting time using water breathing and having a glass of water on your head, or simply be an air genasi) Would the glyph break if you moved the bag of holding, cause technically inside the bag of holding is an extra dimensional space and the space inside the bag isnt moving, but the entrance to it is.
Just want to find out if i can make a bag of buffs
Might depend entirely on the DM
A bag of holding states that it is an "Extradimensional space" which in terms of D&D means demiplanes. This means the Bag of Holding doesn't actually "hold" the glyph, rather the bag acts as a gate to the demiplane. This is why it never changes in weight. As such, unless you turn the bag inside out, the glyph wouldn't be moving away from where it was cast, and therefor "Bag of Buffs" is a completely usable strategy.
TL;DR A glyph of warding in a Bag of Holding, or similar extradimensional storage, would remain stable unless you turn the bag inside out.
Places where D&D refers to extradimensional spaces as demiplanes:
Waterdeep Extradimensional Sanctum
Living Demiplane
Miirym
(Miirym is the most useful as it states "She can’t enter extradimensional spaces, since they are not on the same plane of existence as Candlekeep.")

Given the 1 hour casting time, and the nature of the spell, it should be a Ritual spell.
I tried making a Homebrew version with the Ritual tag, but DnDBeyond complained that it was too similar to the existing spell. DnDBeyond is correct: I'm not looking to change the spell, just to add the Ritual tag.
You can still use it just not publish it for anyone else to use
The glyph cannot move 10ft., you can move away from the glyph. There is no point in spending 200 gold per day, either.
If you cast this and pick the Spell Glyph option, can you prepare a 3rd level spell cast with a 4th level spell slot?
Deleted by the author.
It isn't you that needs to stay within 10 feet, it's the surface or object that they are cast on that cannot move more than 10 feet from the original casting location.
(not trying to be rude, of course)
Excellent use of the wish spell. Let's you drop a nasty concentration spell up to 8th level that doesn't require concentration, since the Glyph will do it.
Portal Hole is the best way to have access to a Glyph you've prepared earlier. You simply lay out the Portable Hole, and then climb down into it. You are now standing on a different Plane of Existence.
"You can use an action to unfold a portable hole and place it on or against a solid surface, whereupon the portable hole creates an extradimensional hole 10 feet deep. The cylindrical space within the hole exists on a different plane, so it can’t be used to create open passages."
You then cast the Glyph on an object, and leave the object on that Plane of Existence. Climb out of the hole and close it up. The object inside the hole will remain where it is, and the Glyph will remain intact.
Then, when you want to access the Glyph, simply deploy the hole as an Action and jump down into it. Trigger the Glyph, and off you go.
you can basically build a computer with this spell alone and it would only take 10 in-game years and * - (incense and powdered diamond worth at least 200 gp, which the spell consumes)X770 and if your ARTIFICER wants to make a giant super cool robot that can do anything this is the spell for him
you can also make a network of spells that activate each others to make a dungeon that attacks the players that enter it with literally any and every spell in existens
this is literally the wish spell with extra steps
Could I use this on a shield?
So the rule says "The glyph can cover an area no larger than 10 feet in diameter. If the surface or object is moved more than 10 feet from where you cast this spell, the glyph is broken, and the spell ends without being triggered."
But if I am carrying the shield and I made the glyph of warding, would it still remain as the shield is never more than 10ft from me?
Thanks
One thing also to note, you need to expend 2 9th level slots in order to do this as
"You can store a prepared spell of 3rd level or lower in the glyph by casting it as part of creating the glyph. The spell must target a single creature or an area. The spell being stored has no immediate effect when cast in this way. When the glyph is triggered, the stored spell is cast. If the spell has a target, it targets the creature that triggered the glyph. If the spell affects an area, the area is centered on that creature. If the spell summons hostile creatures or creates harmful objects or traps, they appear as close as possible to the intruder and attack it. If the spell requires concentration, it lasts until the end of its full duration."
However... with one of the Dragon Foci from Fitzban this is still possible. https://www.dndbeyond.com/magic-items/4047194-dragon-touched-focus. It allows you to cast Glyph of Warding at 9th with your 3rd level slot, then you can cast wish as your 9th.
