What is your spellcasting ability when casting a spell from a Ring of Spell Storing?

The Ring of Spell Storing states (emphasis mine):

[…] While wearing this ring, you can cast any spell stored in it. The spell uses the slot level, spell save DC, spell attack bonus, and spellcasting ability of the original caster, but is otherwise treated as if you cast the spell. […]

So say somebody has acquired such a ring and casts counterspell or dispel magic using it, or is targeted by the Arcane Trickster Rogue’s Spell Thief feature:

[…] If it is casting a spell of 4th level or higher, make an ability check using your spellcasting ability. […]

[…] For each spell of 4th level or higher on the target, make an ability check using your spellcasting ability. The DC equals 10 + the spell’s level. […]

[…] Immediately after a creature casts a spell that targets you or includes you in its area of effect, you can use your reaction to force the creature to make a saving throw with its spellcasting ability modifier. […]

What would “your” or “its” spellcasting ability modifier actually be? Do you use the modifier of whoever put that spell into the ring? Does anything change if you have levels in zero, one, or two classes that can cast spells?

Some related questions:

  • What is the spell attack bonus and spell save DC of a Thief using the Use Magic Device feature?
  • What is the spellcasting ability of a Barbarian Totem Warrior?
  • For the Ring of Shooting Stars, what is the spell save DC of Faerie Fire?
  • What is the spell save DC for this magic item from Waterdeep: Dungeon of the Mad Mage?
  • What is the Wand of Paralysis' Saving Throw?
  • Do racial/feat/non-Spellcasting classes' spellcasting abilities count as a spellcasting ability for Staff of Power?

I believe my question is a bit different from these previous ones because the Ring of Spell Storing explicitly says that the spell uses the original caster’s spellcasting ability and not the spellcasting ability of whatever creature is actually using the ring.

If a platinum ring is removed and then replaced do the effects of Warding Bond resume?

Warding Bond has a duration of 1 hour and has a material requirement of

a pair of platinum rings worth at least 50 gp each, which you and the target must wear for the duration

If one of the two rings is removed does the spell end or are its effects merely suppressed? If the ring is replaced within the 1 hour duration would Warding Bond need to be re-cast or would its effects resume?

Does Ring of Mind Shielding or Mindblank block the Dream spell? If not, what does?

As the question states. What spells and/or effects apart from not sleeping give someone immunity from being contacted with Dream?

It would seem to me that as long as you’re on the same plane as your target and your target is asleep, there is no RAW way for your target to avoid being targeted by Dream.

Does Ring of Free Action give immunity to the Incapacitated Condition?

I am a DM who is planning to have the party finally face off against a criminal mastermind whose signature spell is Modify Memory. However, the party rogue is in posession of a Ring of Free Action. One of the effects of the Ring of Free Action is to make it impossible for magic to reduce your speed. The Modify Memory spell causes incapacitation in order to work, and one of the effects of incapacitation is the inability to move.

The question is, does the Ring of Free Action provide immunity to the Incapacitated condition if it was caused by magic?

Ring of Free Action: While you wear this ring, Difficult Terrain doesn’t cost you extra Movement. In addition, magic can neither reduce your speed nor cause you to be Paralyzed or Restrained.

What counts as “helping slay an elemental” for a Ring of Elemental Command?

The various Rings of Elemental Command in the DMG (p. 190) all have basic abilities that start working as soon as you attune them, but there are other abilities that only start working if you “help slay [an] elemental” of the same type that the ring commands.

As the DM of our current campaign, I’m considering having one of these rings be available to the group, but I’m curious how strict I should be in the interpretation of that “help slay” part. Most of the scenarios I can think of boil down to a version of:

Does dominating an elemental that’s otherwise been minding its own business and having it stand between me and (subsequently get eaten by) the dragon that’s chasing me count as “helping slay” that elemental?

My inclination is that this is perfectly acceptable but I’m curious if there’s a rules clarification on what counts as “slaying” in this case.

For Ring of Shooting Stars, can Ball Lightning affect a creature when you move it into their space?

The Ring of Shooting Stars has the following feature (emphasis mine):

Ball Lightning.

You can expend 2 charges as an action to create one to four 3-foot-diameter spheres of lightning. The more spheres you create, the less powerful each sphere is individually.

Each sphere appears in an unoccupied space you can see within 120 feet of you. The spheres last as long as you concentrate (as if concentrating on a spell), up to 1 minute. Each sphere sheds dim light in a 30-foot radius.

As a bonus action, you can move each sphere up to 30 feet, but no farther than 120 feet away from you. When a creature other than you comes within 5 feet of a sphere, the sphere discharges lightning at that creature and disappears. That creature must make a DC 15 Dexterity saving throw. On a failed save, the creature takes lightning damage based on the number of spheres you created. (4 spheres = 2d4, 3 spheres = 2d6, 2 spheres = 5d4, 1 sphere = 4d12)

Does this mean that the sphere discharges lightning whether you move it within 5 feet of a creature or whether a creature moves within 5 feet of it?

What happens if you move it within 5 feet of multiple creatures at once (or multiple creatures move within 5 feet of it at once)?

After a creature makes a Dex save from Wall of Fire, does it end up inside or outside the ring?

Let’s say a Wizard casts Wall of Fire in the ring shape, choosing the inside of the wall as the side that does damage.

An enemy is in one of the squares on the edge of the ring (ie. one of the 8 squares on the outside of the template for a 20′ diameter circle, and not the 4 inner squares). Therefore, the enemy must make a Dex save and might take 5d8 damage.

If it makes the save, is it inside the ring?

If it fails the save, is it inside the ring?

Here is a good reference for the way the damage works: Ringed Wall of Fire: How does the damage sequence go?

How does Ring of X-Ray Vision interact with Illusion spells and similar effects?

Specifically, the ring states that “solid Objects within that radius appear transparent and don’t prevent light from passing through them”. Does it apply to solid objects created through illusion?

It seems unlikely that the ring works selectively, and illusions can’t plausibly “know” they are being viewed in that way.

By extension, the Ring of X-Ray Vision seems to allow its wearer to inspect the internal organs of a person (be it through selective sight if we consider it to work like Superman’s X-Ray Vision, or by standing 30 ft from the intended target so that the target’s body is only partially within the ring’s radius (RAW explanation). If that’s the case, do spells like Disguise Self also disguise the internal organs of an affected character in such a way as to fool a person with a Ring of X-Ray Vision?

For example, would the user of Ring of X-Ray Vision be able to tell if a target has a second heart, or has only one lung, or is undead (dead organs) if that target is affected by spells like Disguise Self?

Moreover, would a Ring of X-Ray Vision allow its user to see selectively through clothes? If so, what about illusory clothes and other illusory objects? I am thinking that it should, otherwise its wearer could use it to automatically detect any illusion, which is not what it says in the description (no truesight, just see through solid objects).
