I was running a session a few days ago for some high-level characters and in the palace vault they found themselves an Efreeti Bottle. I rolled for the efreeti's response to being released per the DMG, and wouldn't you know it, they got the result:

91-00: The efreeti can cast the wish spell three times for you. It disappears when it grants the final wish or after 1 hour, and the bottle loses its magic.

The efreeti pops out and reluctantly greets them and spells out what they've found. After the excitement subsides, the predictable line of thinking comes about and they discuss wishing for more wishes, which I shoot down as cosmic law dictates this and that, and we all understandingly nod our heads and move on.

But as I reread the section on the Efreeti Bottle and skimmed through the Efreeti in the Monster Manual, there's really nothing per RAW that would prevent a character from making a wish like "I wish you would grant me 10 more wishes" immediately followed by something like "I wish you would disappear after 1 year instead of 1 hour".

So if a character gets a hold of an Efreeti Bottle and essentially wishes for more wishes, per RAW, does it work?

Per RAW the DM decides about wishes.

You did the right thing. The PHB treatment of wish is pretty clear about - beyond the duplication of other spells - wish being finally adjudicated by the DM. The DMG does not counter that with any further guidance on the results of wishes. This makes it simplest to treat any wish as an iteration of the wish spell.

State your wish to the DM as precisely as possible. The DM has great
latitude in ruling what occurs in such an instance; the greater the
wish, the greater the likelihood that something goes wrong. (PHB, p. 289)

It is often simpler for the DM to advise the player "it doesn't work that way, try another approach" than to spend the effort to dream up whatever goes wrong. On the other hand, sometimes dreaming up what goes wrong can result in hilarity and fun at the table.

As a DM, go with what works best for your table.

For a darker feel, consider the trope that has grown up around the 1902 short story The Monkey's Paw - each wish granted comes with a hellish price. (Thank you to @ChrisFernandez)

As @guildsbounty points out, older editions encouraged the DM to gleefully corrupt any loopholes in a wish phrased by a player. An Efreeti that knew you were trying to manipulate it would find a loophole in your phrasing.

"I wish you would grant me 100 wishes" could easily be corrupted into "Here, let me pick the 100 most demented, destructive wishes I have ever granted for anyone, and grant them for you...all at once."

The Efreeti has technically lived up to the bargain - he granted you 100 wishes, just not 100 wishes of your choice.

That's not a stated power of wish.

The wish spell description states:

You might be able to achieve something beyond the scope of the above examples. State your wish to the DM as precisely as possible. The DM has great latitude in ruling what occurs in such an instance, the greater the wish, the greater the likelihood that something goes wrong. This spell might simply fail, the effect you desire might only be partly achieved, or you might suffer some unforeseen consequence as a result of how you worded the wish. For example, wishing that a villain were dead might propel you forward in time to a period when that villain is no longer alive, effectively removing you from the game. Similarly, wishing for a legendary magic item or artifact might instantly transport you to the presence of the item's current owner.

If they wish for something that isn't a stated power of wish (the closest is an eighth-level spell, and this is 10 ninth-level spells) then you can mess with them as you wish.

As a suggestion, perhaps they could be transported to the City of Brass, and given a chance to ask efreeti there for 10 more wishes or be slaughtered by angry efreeti.

There is actually something that limits the ability to do this - the rules of casting such a wish itself.

The stress of casting this spell to produce any effect other than duplicating another spell weakens you. After enduring that stress, each time you cast a spell until you finish a long rest, you take 1d10 necrotic damage per level of that spell. This damage can't be reduced or prevented in any way. In addition, your Strength drops to 3, if it isn't 3 or lower already, for 2d4 days. For each of those days that you spend Resting and doing nothing more than light activity, your remaining recovery time decreases by 2 days. Finally, there is a 33 percent chance that you are unable to cast wish ever again if you suffer this stress.

So the limiting factors listed here, for the Efreeti, include the following:

• Making two wish spells in a row like this would cause the Efreeti to take 9d10 Necrotic damage. This won't kill the Efreeti, but it could seriously damage it, and more castings like this could kill it.


• Every time they cast Wish outside of the duplication of 8th level spells or the listed possible effects, there's a 33% chance they can never cast it again.

So if you're going by RAW, these are the limits of what the PCs can get out of their 3 wishes.

Mind, you don't have to go by RAW, and it might be more fun to ignore this caveat for the Efreeti's wishes. That is up to you as the DM to decide - but if you're following the rules as written, then you need to take this into account.

No you can't because the Genie is bound by cosmic laws

There is actually a cosmic law limiting each Genie that can grant wishes to only grant three to a given creature. This is detailed in the Monster Manual entry on genies (under the VARIANT: GENIE POWERS sidebar on p. 144):

Wishes. [...] A particular genie that has this power can grant one to three wishes to a creature that isn’t a genie. Once a genie has granted its limit of wishes, it can’t grant wishes again for some amount of time (usually 1 year), and cosmic law dictates that the same genie can expend its limit of wishes on a specific creature only once in that creature’s existence.

For clarity, regular genies (as set out in their stat block) don't have the power to grant wishes, and the Monster Manual lore section on genies makes this clear:

All genies command the power of their native element, but a rare few also possess the power to grant wishes.

Thus the genie in the bottle is one of the rare genies that possesses this power and is covered by the rules in the variant sidebar mentioned above.

(Unless otherwise stated all emphasis is mine)

One thing you should be aware of as the DM is that in the same variant sidebar about wishes it states:

Depending on the genie’s nature, the genie might try to pervert the intent of the wish by exploiting the wish’s poor wording. The perversion of the wording is usually crafted to be to the genie’s benefit.
