You create linked teleportation portals. Choose two Large, unoccupied spaces on the ground that you can see, one space within range and the other one within 10 feet of you. A circular portal opens in each of those spaces and remains for the duration.
The portals are two-dimensional glowing rings filled with mist that blocks sight. They hover inches from the ground and are perpendicular to it.
A portal is open on only one side (you choose which). Anything entering the open side of a portal exits from the open side of the other portal as if the two were adjacent to each other. As a Bonus Action, you can change the facing of the open sides.
Protective magical frost surrounds you. You gain 5 Temporary Hit Points. If a creature hits you with a melee attack roll before the spell ends, the creature takes 5 Cold damage. The spell ends early if you have no Temporary Hit Points.
Using a Higher-Level Spell Slot. The Temporary Hit Points and the Cold damage both increase by 5 for each spell slot level above 1.
Invoking Hadar, you cause tendrils to erupt from yourself. Each creature in a 10-foot Emanation originating from you makes a Strength saving throw. On a failed save, a target takes 2d6 Necrotic damage and can’t take Reactions until the start of its next turn. On a successful save, a target takes half as much damage only.
Using a Higher-Level Spell Slot. The damage increases by 1d6 for each spell slot level above 1.
You and up to eight willing creatures within range project your astral bodies into the Astral Plane (the spell ends instantly if you are already on that plane). Each target’s body is left behind in a state of suspended animation. It has the Unconscious condition, doesn't need food or air, and doesn't age.
A target's astral form resembles its body in almost every way, replicating its game statistics and possessions. The principal difference is the addition of a silvery cord that trails from between the shoulder blades of the astral form. The cord fades from view after 1 foot. If the cord is cut – which happens only when an effect states that it does so – the target's body and astral form both die.
A target's astral form can travel through the Astral Plane. The moment an astral form leaves that plane, the target's body and possessions travel along the silver cord, causing the target to re-enter its body on the new plane.
Any damage or other effects that apply to an astral form have no effect on the target's body and vice versa. If a target's body or astral form drops to 0 Hit Points, the spell ends for that target. The spell ends for all the targets if you take a Magic action to dismiss it.
When the spell ends for a target who isn't dead, the target reappears in its body and exits the state of suspended animation.
Up to three creatures of your choice that you can see within range must each make a Charisma saving throw. Whenever a target that fails this save makes an attack roll or a saving throw before the spell ends, the target must subtract 1d4 from the attack roll or save.
Using a Higher-Level Spell Slot. You can target one additional creature for each spell slot level above 1.
Casting Time: Bonus Action, which you take immediately after hitting a creature with a Melee weapon or an Unarmed Strike
The target hit by the attack roll takes an extra 5d10 Force damage from the attack. If the attack reduces the target to 50 Hit Points or fewer, the target 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.
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.
You blast the mind of a creature that you can see within range. The target makes an Intelligence saving throw.
On a failed save, the target takes 10d12 Psychic damage and can’t cast spells or take the Magic action. At the end of every 30 days, the target repeats the save, ending the effect on a success. The effect can also be ended by the Greater Restoration, Heal, or Wish spell.
On a successful save, the target takes half as much damage only.
You create a blade-shaped planar rift about 3 feet long in an unoccupied space you can see within range. The blade lasts for the duration. When you cast this spell, you can make up to two melee spell attacks with the blade, each one against a creature, loose object, or structure within 5 feet of the blade. On a hit, the target takes 4d12 force damage. This attack scores a critical hit if the number on the d20 is 18 or higher. On a critical hit, the blade deals an extra 8d12 force damage (for a total of 12d12 force damage).
As a bonus action on your turn, you can move the blade up to 30 feet to an unoccupied space you can see and then make up to two melee spell attacks with it again.
The blade can harmlessly pass through any barrier, including a Wall of Force.
