Djinni

If the monster dies outside the Elemental Plane of Air, its body dissolves into dirt, and it gains a new body in days, reviving with all its Hit Points somewhere on the Plane of Air.

The monster has Advantage on saving throws against spells and other magical effects.

The monster has a 30 percent chance of knowing the Wish spell. If the monster knows it, the monster can cast it only on behalf of a non-genie creature who communicates a wish in a way the monster can understand. If the monster casts the spell for the creature, the monster suffers none of the spell's stress. Once the monster has cast it three times, the monster can't do so again for 365 days.

Wish is the mightiest spell a mortal can cast. By simply speaking aloud, you can alter reality itself. The basic use of this spell is to duplicate any other spell of level 8 or lower. If you use it this way, you don't need to meet any requirements to cast that spell, including costly components. The spell simply takes effect. Alternatively, you can create one of the following effects of your choice:Object Creation. You create one object of up to 25,000 GP in value that isn't a magic item. The object can be no more than 300 feet in any dimension, and it appears in an unoccupied space that you can see on the ground. Instant Health. You allow yourself and up to twenty creatures that you can see to regain all Hit Points, and you end all effects on them listed in the Greater Restoration spell. Resistance. You grant up to ten creatures that you can see Resistance to one damage type that you choose. This Resistance is permanent. Spell Immunity. You grant up to ten creatures you can see immunity to a single spell or other magical effect for 8 hours. Sudden Learning. You replace one of your feats with another feat for which you are eligible. You lose all the benefits of the old feat and gain the benefits of the new one. You can't replace a feat that is a prerequisite for any of your other feats or features. Roll Redo. You undo a single recent event by forcing a reroll of any die roll made within the last round (including your last turn). Reality reshapes itself to accommodate the new result. For example, a Wish spell could undo an ally's failed saving throw or a foe's Critical Hit. You can force the reroll to be made with Advantage or Disadvantage, and you choose whether to use the reroll or the original roll. Reshape Reality. You may wish for something not included in any of the other effects. To do so, 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 be achieved only in part, or you might suffer an 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 an Artifact might instantly transport you to the presence of the item's current owner. If your wish is granted and its effects have consequences for a whole community, region, or world, you are likely to attract powerful foes. If your wish would affect a god, the god's divine servants might instantly intervene to prevent it or to encourage you to craft the wish in a particular way. If your wish would undo the multiverse itself, threaten the City of Sigil, or affect the Lady of Pain in any way, you see an image of her in your mind for a moment; she shakes her head, and your wish fails. The stress of casting Wish 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 score becomes 3 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.

The monster makes three attacks, using Storm Blade or Storm Bolt in any combination.

The monster casts one of the following spells, requiring no Material components and using Charisma as the spellcasting ability: At Will: Detect Evil and Good, Detect Magic 2/Day Each: Create Food and Water (can create wine instead of water), Tongues, Wind Walk 1/Day Each: Creation, Gaseous Form, Invisibility, Major Image, Plane Shift

For the duration, you sense the location of any Aberration, Celestial, Elemental, Fey, Fiend, or Undead within 30 feet of yourself. You also sense whether the Hallow spell is active there and, if so, where. The spell is blocked by 1 foot of stone, dirt, or wood; 1 inch of metal; or a thin sheet of lead.

For the duration, you sense the presence of magical effects within 30 feet of yourself. If you sense such effects, you can take the Magic action to see a faint aura around any visible creature or object in the area that bears the magic, and if an effect was created by a spell, you learn the spell's school of magic. The spell is blocked by 1 foot of stone, dirt, or wood; 1 inch of metal; or a thin sheet of lead.

You create 45 pounds of food and 30 gallons of fresh water on the ground or in containers within range—both useful in fending off the hazards of malnutrition and dehydration. The food is bland but nourishing and looks like a food of your choice, and the water is clean. The food spoils after 24 hours if uneaten.

This spell grants the creature you touch the ability to understand any spoken or signed language that it hears or sees. Moreover, when the target communicates by speaking or signing, any creature that knows at least one language can understand it if that creature can hear the speech or see the signing.

You and up to ten willing creatures of your choice within range assume gaseous forms for the duration, appearing as wisps of cloud. While in this cloud form, a target has a Fly Speed of 300 feet and can hover; it has Immunity to the Prone condition; and it has Resistance to Bludgeoning, Piercing, and Slashing damage. The only actions a target can take in this form are the Dash action or a Magic action to begin reverting to its normal form. Reverting takes 1 minute, during which the target has the Stunned condition. Until the spell ends, the target can revert to cloud form, which also requires a Magic action followed by a 1-minute transformation. If a target is in cloud form and flying when the effect ends, the target descends 60 feet per round for 1 minute until it lands, which it does safely. If it can't land after 1 minute, it falls the remaining distance.

You pull wisps of shadow material from the Shadowfell to create an object within range. It is either an object of vegetable matter (soft goods, rope, wood, and the like) or mineral matter (stone, crystal, metal, and the like). The object must be no larger than a 5-foot Cube, and the object must be of a form and material that you have seen. The spell's duration depends on the object's material, as shown in the Materials table. If the object is composed of multiple materials, use the shortest duration. Using any object created by this spell as another spell's Material component causes the other spell to fail.

The Cube increases by 5 feet for each spell slot level above 5.

A willing creature you touch shape-shifts, along with everything it's wearing and carrying, into a misty cloud for the duration. The spell ends on the target if it drops to 0 Hit Points or if it takes a Magic action to end the spell on itself. While in this form, the target's only method of movement is a Fly Speed of 10 feet, and it can hover. The target can enter and occupy the space of another creature. The target has Resistance to Bludgeoning, Piercing, and Slashing damage; it has Immunity to the Prone condition; and it has Advantage on Strength, Dexterity, and Constitution saving throws. The target can pass through narrow openings, but it treats liquids as though they were solid surfaces. The target can't talk or manipulate objects, and any objects it was carrying or holding can't be dropped, used, or otherwise interacted with. Finally, the target can't attack or cast spells. Using a Higher-Level Spell Slot. You can target one additional creature for each spell slot level above 3.

A creature you touch has the Invisible condition until the spell ends. The spell ends early immediately after the target makes an attack roll, deals damage, or casts a spell. Using a Higher-Level Spell Slot. You can target one additional creature for each spell slot level above 2.

You create the image of an object, a creature, or some other visible phenomenon that is no larger than a 20-foot Cube. The image appears at a spot that you can see within range and lasts for the duration. It seems real, including sounds, smells, and temperature appropriate to the thing depicted, but it can't deal damage or cause conditions. If you are within range of the illusion, you can take a Magic action to cause the image to move to any other spot within range. As the image changes location, you can alter its appearance so that its movements appear natural for the image. For example, if you create an image of a creature and move it, you can alter the image so that it appears to be walking. Similarly, you can cause the illusion to make different sounds at different times, even making it carry on a conversation, for example. Physical interaction with the image reveals it to be an illusion, for things can pass through it. A creature that takes a Study action to examine the image can determine that it is an illusion with a successful check against your spell save DC. If a creature discerns the illusion for what it is, the creature can see through the image, and its other sensory qualities become faint to the creature. Using a Higher-Level Spell Slot. The spell lasts until dispelled, without requiring Concentration, if cast with a level 4+ spell slot.

You and up to eight willing creatures who link hands in a circle are transported to a different plane of existence. You can specify a target destination in general terms, such as the City of Brass on the Elemental Plane of Fire or the palace of Dispater on the second level of the Nine Hells, and you appear in or near that destination, as determined by the DM. Alternatively, if you know the sigil sequence of a teleportation circle on another plane of existence, this spell can take you to that circle. If the teleportation circle is too small to hold all the creatures you transported, they appear in the closest unoccupied spaces next to the circle.
