You open a gateway to the Far Realm, a region infested with unspeakable horrors. A 20-foot-radius Sphere of Darkness appears, centered on a point with range and lasting for the duration. The Sphere is Difficult Terrain, and it is filled with strange whispers and slurping noises, which can be heard up to 30 feet away. No light, magical or otherwise, can illuminate the area, and creatures fully within it have the Blinded condition.
Any creature that starts its turn in the area takes 2d6 Cold damage. Any creature that ends its turn there must succeed on a Dexterity saving throw or take 2d6 Acid damage from otherworldly tentacles.
Using a Higher-Level Spell Slot. The Cold or Acid damage (your choice) increases by 1d6 for each spell slot level above 3.
You summon an otherworldly being that appears as a loyal steed in an unoccupied space of your choice within range. This creature uses the Otherworldly Steed stat block. If you already have a steed from this spell, the steed is replaced by the new one.
The steed resembles a Large, rideable animal of your choice, such as a horse, a camel, a dire wolf, or an elk. Whenever you cast the spell, choose the steed’s creature type—Celestial, Fey, or Fiend—which determines certain traits in the stat block.
Combat. The steed is an ally to you and your allies. In combat, it shares your Initiative count, and it functions as a controlled mount while you ride it (as defined in the rules on mounted combat). If you have the Incapacitated condition, the steed takes its turn immediately after yours and acts independently, focusing on protecting you.
Disappearance of the Steed. The steed disappears if it drops to 0 Hit Points or if you die. When it disappears, it leaves behind anything it was wearing or
carrying. If you cast this spell again, you decide whether you summon the steed that disappeared or a different one.
Otherworldly Steed
Large Celestial, Fey, or Fiend (Your Choice), Neutral
AC 10 + 1 per spell level
HP 5 + 10 per spell level (the steed has a number of Hit Dice [d10s] equal to the spell’s level)
Speed 60 ft., Fly 60 ft. (requires level 4+ spell)
You attempt to interrupt a creature in the process of casting a spell. The creature makes a Constitution saving throw. On a failed save, the spell dissipates with no effect, and the action, Bonus Action, or Reaction used to cast it is wasted. If that spell was cast with a spell slot, the slot isn’t expended.
A Line of strong wind 60 feet long and 10 feet wide blasts from you in a direction you choose for the duration. Each creature in the Line must succeed on a Strength saving throw or be pushed 15 feet away from you in a direction following the Line. A creature that ends its turn in the Line must make the same save.
Any creature in the Line must spend 2 feet of movement for every 1 foot it moves when moving closer to you.
The gust disperses gas or vapor, and it extinguishes candles and similar unprotected flames in the area. It causes protected flames, such as those of lanterns, to dance wildly and has a 50 percent chance to extinguish them.
As a Bonus Action on your later turns, you can change the direction in which the Line blasts from you.
You try to compel a creature into a duel. One creature that you can see within range makes a Wisdom saving throw. On a failed save, the target has Disadvantage on attack rolls against creatures other than you, and it can’t willingly move to a space that is more than 30 feet away from you.
The spell ends if you make an attack roll against a creature other than the target, if you cast a spell on an enemy other than the target, if an ally of yours damages the target, or if you end your turn more than 30 feet away from the target.
A bright streak flashes from you to a point you choose within range and then blossoms with a low roar into a fiery explosion. Each creature in a 20-foot-radius Sphere centered on that point makes a Dexterity saving throw, taking 8d6 Fire damage on a failed save or half as much damage on a successful one.
Flammable objects in the area that aren’t being worn or carried start burning.
Using a Higher-Level Spell Slot. The damage increases by 1d6 for each spell slot level above 3.
You touch another creature that is willing and create a mystic connection between you and the target until the spell ends. While the target is within 60 feet of you, it gains a +1 bonus to AC and saving throws, and it has Resistance to all damage. Also, each time it takes damage, you take the same amount of damage.
The spell ends if you drop to 0 Hit Points or if you and the target become separated by more than 60 feet. It also ends if the spell is cast again on either of the connected creatures.
Briefly surrounded by silvery mist, you teleport up to 30 feet to an unoccupied space you can see.
One creature that you can see within range must succeed on a Charisma saving throw or be transported to a harmless demiplane for the duration. While there, the target has the Incapacitated condition. When the spell ends, the target reappears in the space it left or in the nearest unoccupied space if that space is occupied.
If the target is an Aberration, a Celestial, an Elemental, a Fey, or a Fiend, the target doesn’t return if the spell lasts for 1 minute. The target is instead transported to a random location on a plane (DM’s choice) associated with its creature type.
Using a Higher-Level Spell Slot. You can target one additional creature for each spell slot level above 4.
