This is looking at what appears to be a somewhat bizarre rules exploit, and attempting to determine if it is, in fact, viable under the rules.
Premise
We have a Bard who likes having friends – a lot of friends. He has Find Familiar. At level 10, he takes Find Steed and Find Greater Steed as his magical secrets and the DM has given him a ring of Spell storing.
Now, it's pretty clear that by himself, he can have one Familiar, one Greater Steed, and one Steed (perhaps a mastiff, because he wants a dog, and can't ride two things at once). We'll say that he chooses a hawk as his familiar.
Can the bard allow the creatures summoned by the spells to attune to and use the ring of spell storing containing Find/Familiar spells to summon Steeds/Familiars of their own?
A DM might adjudicate that a hawk/mastiff/griffin has no fingers and cannot use a ring, but Polymorph is available to a Bard of that level, and seems like it should be able to handle the issue for the Steed and Greater Steed. (I'm not sure if there are any beasts of low enough CR for the familiar that would have something appropriately finger-like.)
Is there a reason why the dog would not be able to have a perfectly loyal griffin of its own? Is there any real limit to the potential pyramid of perfect loyalty/obedience that would result?
This is in some ways similar to the linked question, and may have the same answer, but it is distinct on a couple of points.
- The first is that the linked question is about the Pact of the Chain
familiar, most of which have obvious fingers already, as compared to
the generic Familiar, Steed, and Greater Steed. -
The second is that this question is specifically about the three Find
spells, which seem like they might be a special case – it's not
merely about whether your dog (polymorphed into an
octopus/monkey/whatever) is able to cast the spell, but whether they
are able to permanently maintain the found creature afterwards.In particular, this seems to severely break the intended limit of one steed, greater steed, and familiar per PC, and it seemed like there might be some further limit in place preventing it from working out this way.
Best Answer
All the way down (it works*)
As you've thought, there is nothing in this that creates any rules issues.
You've hit the pertinent points:
Any creature can attune to the Ring of Spell Storing
Whomever is attuned, including beasts, to the Ring of Spell Storing can cast a spell from it:
Find Familiar, Find Steed, and Find Greater Steed are all 5th level spells or below and viable to be stored in the ring.
This shows that your belief that this should work is in fact correct.
There is one problem
You personally can't have Find Steed and Find Greater Steed going simultaneously. Find Greater Steed explicitly states:
However, that just limits your starting set to 2 creatures and they can do this again. You just don't start with three.
A DM's option
Having said that, the DM can still put the kibosh on this if they feel it's taking away from the table or other players. One player having a huge array of creatures at their disposal may cause issues with other players to the point where it becomes unfun. That's going to be up to the table, the players, and the DM.
*The only issue to really consider is if the animals have the right appendage. It's important to note that if you do use polymorph to get around that, then the creatures will lose their intelligence and drop back down to whatever the new stat block says it is. A DM can rule that creatures of low enough intelligence aren't able to understand how to utilize the magic item or be able to maintain concentration for the casting durations.
