Can a 10th Lvl Chronurgy Wizard use its Arcane Abeyance on a spell cast into a Spell Glyph?

Question

(So far as I can tell, this isn't comparable to Wristpocket...)

In this scenario, let's say a 10th Lvl Chronurgy Wizard, casts Magic Circle into a Glyph of Warding spell glyph, & applies Arcane Abeyance to the casting of Magic Circle:

When a creature triggers the glyph, does that spell glyph produce a Magic Circle spell reserved for 1hr within an Arcane Abeyance bead?

I see a few limitations:

Any spell cast via a spell glyph, targets the creature triggering the glyph or an area centered on that creature.

A spell cast with Arcane Abeyance uses the Concentration of whatever creature uses the bead as an Action.

Would anything in RAW disallow this glyph-makes-bead combo? If not, then are there any problematic points a DM should be aware of before allowing it?

Answer 1

No.

This combo would produce:

1. a spell glyph that casts magic circle, and
2. an Arcane Abeyance bead that has no effect when activated.

From glyph of warding:

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 being stored has no immediate effect when cast in this way. When the glyph is triggered, the stored spell is cast.

A spell glyph causes the spell cast into it to have no effect. It then casts the spell anew when triggered. Note that the text does not say that "the glyph releases the stored spell," it says "the stored spell is cast."

From Arcane Abeyance:

The spell is frozen in time at the moment of casting and held within a gray bead for 1 hour... A creature holding the bead can use its action to release the spell within...

Arcane Abeyance delays the effect of a spell until a creature uses an action to release it. However, a spell cast in the creation of a spell glyph has no effect, so activating the bead created in this way would also produce no effect.

As a side note, Arcane Abeyance does not directly modify the effect of a spell, so even if glyph of warding delayed the effect of the stored spell rather than casting it anew, there is still no way that a spell glyph could produce an Arcane Abeyance bead.

Answer 2

No.

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.

At 10th level, when you cast a spell using a spell slot of 4th level or lower, you can condense the spell's magic into a mote. The spell is frozen in time at the moment of casting and held within a gray bead for 1 hour.

Emphasis mine; in order to successfully cast a Glyph of Warding: Spell Glyph, you must store the spell as part of creating the glyph, which happens in the same casting action.

This is impossible in your setup, because the spell is instead stored inside the bead, rather than inside the glyph. You cannot store the bead inside the glyph, because until it releases the spell, it is not the spell.

Unable to fulfill its prerequisite of storing the spell in the glyph when you cast it, the entire spell fails, and the slot is wasted.

One might think there's a way around this by releasing the spell from the bead as you cast a glyph, since -

A creature holding the bead can use its action to release the spell within, whereupon the bead disappears. The spell uses your spell attack bonus and save DC, and the spell treats the creature who released it as the caster for all other purposes

But this also doesn't work, since releasing the spell from the bead takes an action, and you must store the spell as part of creating the glyph, which means it must happen in the same unbroken casting as the action you cast the glyph with.

Answer 3

It should work as you described

Glyph of Warding:

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.

Arcane Abeyance:

At 10th level, when you cast a spell using a spell slot of 4th level or lower, you can condense the spell's magic into a mote. The spell is frozen in time at the moment of casting and held within a gray bead for 1 hour.

Both descriptions use the words 'casting' and 'cast' while not explaining the distinction. My memory of grammar is that casting would refer to the process as it's happening and cast would be the entire completed action. So, when you are 'casting' the spell into the glyph, you activate Arcane Abeyance as a sort of triggered reaction because the requirements are met. When the glyph trigger is activated, the bead would pop out in the space of the triggering creature.

The process of casting this, according to Storing long cast time spells in a glyph, would go like this:

1. Begin casting Glyph of Warding for hour.
2. At the end of 1 hour, begin casting Magic Circle for 1 minute.
3. At the end of this, the final action is used to complete the casting, and the glyph is instantaneously inscribed, triggering the free action of Arcane Abeyance.

This wouldn't do anything special that you couldn't do with either feature individually

Since Arcane Abeyance only affects spells of 4th level or lower, the really abuse prone spells are omitted. Plus, Glyph of Warding only applies to targeting single creatures or areas, so spells with a range of Self aren't possilbe. The resulting list is large, but shouldn't break any games.
