Archmage

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

The monster makes four Arcane Burst attacks.

Melee Attack: +9 to hit. reach 5 ft. Hit: 4d10 + 5 force damage.

The monster casts Misty Step, requiring no spell components and using the same spellcasting ability as Spellcasting.

Briefly surrounded by silvery mist, you teleport up to 30 feet to an unoccupied space you can see.

The monster casts Counterspell or Shield in response to the spell's trigger, using the same spellcasting ability as Spellcasting.

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.

An imperceptible barrier of magical force protects you. Until the start of your next turn, you have a +5 bonus to AC, including against the triggering attack, and you take no damage from Magic Missile.

The monster casts one of the following spells, using Intelligence as the spellcasting ability: At Will: Detect Magic, Detect Thoughts, Disguise Self, Invisibility, Light, Mage Armor (included in AC), Mage Hand, Prestidigitation 2/Day Each: Fly, Lightning Bolt (level 7 version) 1/Day Each: Cone of Cold (level 9 version), Mind Blank (cast before combat), Scrying, Teleport

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 activate one of the effects below. Until the spell ends, you can activate either effect as a Magic action on your later turns. Sense Thoughts. You sense the presence of thoughts within 30 feet of yourself that belong to creatures that know languages or are telepathic. You don't read the thoughts, but you know that a thinking creature is present. The spell is blocked by 1 foot of stone, dirt, or wood; 1 inch of metal; or a thin sheet of lead. Read Thoughts. Target one creature you can see within 30 feet of yourself or one creature within 30 feet of yourself that you detected with the Sense Thoughts option. You learn what is most on the target's mind right now. If the target doesn't know any languages and isn't telepathic, you learn nothing. As a Magic action on your next turn, you can try to probe deeper into the target's mind. If you probe deeper, the target makes a Wisdom saving throw. On a failed save, you discern the target's reasoning, emotions, and something that looms large in its mind (such as a worry, love, or hate). On a successful save, the spell ends. Either way, the target knows that you are probing into its mind, and until you shift your attention away from the target's mind, the target can take an action on its turn to make an check against your spell save DC, ending the spell on a success.

You make yourself—including your clothing, armor, weapons, and other belongings on your person—look different until the spell ends. You can seem 1 foot shorter or taller and can appear heavier or lighter. You must adopt a form that has the same basic arrangement of limbs as you have. Otherwise, the extent of the illusion is up to you. The changes wrought by this spell fail to hold up to physical inspection. For example, if you use this spell to add a hat to your outfit, objects pass through the hat, and anyone who touches it would feel nothing. To discern that you are disguised, a creature must take the Study action to inspect your appearance and succeed on an check against your spell save DC.

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 touch one Large or smaller object that isn't being worn or carried by someone else. Until the spell ends, the object sheds Bright Light in a 20-foot radius and Dim Light for an additional 20 feet. The light can be colored as you like. Covering the object with something opaque blocks the light. The spell ends if you cast it again.

You touch a willing creature who isn't wearing armor. Until the spell ends, the target's base AC becomes 13 plus its Dexterity modifier. The spell ends early if the target dons armor.

You create a magical effect within range. Choose the effect from the options below. If you cast this spell multiple times, you can have up to three of its non-instantaneous effects active at a time. Sensory Effect. You create an instantaneous, harmless sensory effect, such as a shower of sparks, a puff of wind, faint musical notes, or an odd odor. Fire Play. You instantaneously light or snuff out a candle, a torch, or a small campfire. Clean or Soil. You instantaneously clean or soil an object no larger than 1 cubic foot. Minor Sensation. You chill, warm, or flavor up to 1 cubic foot of nonliving material for 1 hour. Magic Mark. You make a color, a small mark, or a symbol appear on an object or a surface for 1 hour. Minor Creation. You create a nonmagical trinket or an illusory image that can fit in your hand. It lasts until the end of your next turn. A trinket can deal no damage and has no monetary worth.

You touch a willing creature. For the duration, the target gains a Fly Speed of 60 feet and can hover. When the spell ends, the target falls if it is still aloft unless it can stop the fall. Using a Higher-Level Spell Slot. You can target one additional creature for each spell slot level above 3.

A stroke of lightning forming a 100-foot-long, 5-foot-wide Line blasts out from you in a direction you choose. Each creature in the Line makes a Dexterity saving throw, taking 8d6 Lightning damage on a failed save or half as much damage on a successful one. Using a Higher-Level Spell Slot. The damage increases by 1d6 for each spell slot level above 3.

You unleash a blast of cold air. Each creature in a 60-foot Cone originating from you makes a Constitution saving throw, taking 8d8 Cold damage on a failed save or half as much damage on a successful one. A creature killed by this spell becomes a frozen statue until it thaws. Using a Higher-Level Spell Slot. The damage increases by 1d8 for each spell slot level above 5.

Until the spell ends, one willing creature you touch has Immunity to Psychic damage and the Charmed condition. The target is also unaffected by anything that would sense its emotions or alignment, read its thoughts, or magically detect its location, and no spell—not even Wish—can gather information about the target, observe it remotely, or control its mind.

You can see and hear a creature you choose that is on the same plane of existence as you. The target makes a Wisdom saving throw, which is modified (see the tables below) by how well you know the target and the sort of physical connection you have to it. The target doesn't know what it is making the save against, only that it feels uneasy. Your Knowledge of the Target Is …Save ModifierSecondhand (heard of the target)+5Firsthand (met the target)+0Extensive (know the target well)−5You Have the Target's …Save ModifierPicture or other likeness−2Garment or other possession−4Body part, lock of hair, or bit of nail−10On a successful save, the target isn't affected, and you can't use this spell on it again for 24 hours. On a failed save, the spell creates an Invisible, intangible sensor within 10 feet of the target. You can see and hear through the sensor as if you were there. The sensor moves with the target, remaining within 10 feet of it for the duration. If something can see the sensor, it appears as a luminous orb about the size of your fist. Instead of targeting a creature, you can target a location you have seen. When you do so, the sensor appears at that location and doesn't move.

This spell instantly transports you and up to eight willing creatures that you can see within range, or a single object that you can see within range, to a destination you select. If you target an object, it must be Large or smaller, and it can't be held or carried by an unwilling creature. The destination you choose must be known to you, and it must be on the same plane of existence as you. Your familiarity with the destination determines whether you arrive there successfully. The DM rolls and consults the Teleportation Outcome table and the explanations after it.

Here are the meanings of the terms in the table's Familiarity column:"Permanent circle" means a permanent teleportation circle whose sigil sequence you know."Linked object" means you possess an object taken from the desired destination within the last six months, such as a book from a wizard's library."Very familiar" is a place you have visited often, a place you have carefully studied, or a place you can see when you cast the spell."Seen casually" is a place you have seen more than once but with which you aren't very familiar."Viewed once or described" is a place you have seen once, possibly using magic, or a place you know through someone else's description, perhaps from a map."False destination" is a place that doesn't exist. Perhaps you tried to scry an enemy's sanctum but instead viewed an illusion, or you are attempting to teleport to a location that no longer exists. Mishap. The spell's unpredictable magic results in a difficult journey. Each teleporting creature (or the target object) takes damage, and the DM rerolls on the table to see where you wind up (multiple mishaps can occur, dealing damage each time). Similar Area. You and your group (or the target object) appear in a different area that's visually or thematically similar to the target area. You appear in the closest similar place. If you are heading for your home laboratory, for example, you might appear in another person's laboratory in the same city. Off Target. You and your group (or the target object) appear miles away from the destination in a random direction. Roll for the direction: 1, east; 2, southeast; 3, south; 4, southwest; 5, west; 6, northwest; 7, north; or 8, northeast. On Target. You and your group (or the target object) appear where you intended.

A spectral, floating hand appears at a point you choose within range. The hand lasts for the duration. The hand vanishes if it is ever more than 30 feet away from you or if you cast this spell again. When you cast the spell, you can use the hand to manipulate an object, open an unlocked door or container, stow or retrieve an item from an open container, or pour the contents out of a vial. As a Magic action on your later turns, you can control the hand thus again. As part of that action, you can move the hand up to 30 feet. The hand can't attack, activate magic items, or carry more than 10 pounds.
