PHB

Shapechange

9-level Transmutation

You assume the form of a different creature for the duration. The new form can be of any creature with a challenge rating equal to your level or lower. The creature can’t be a construct or an undead, and you must have seen the sort of creature at least once. You transform into an average example of that creature, one without any class levels or the Spellcasting trait. Your game statistics are replaced by the statistics of the chosen creature, though you retain your alignment and Intelligence, Wisdom, and Charisma scores. You also retain all of your skill and saving throw proficiencies, in addition to gaining those of the creature. If the creature has the same proficiency as you and the bonus listed in its statistics is higher than yours, use the creature’s bonus in place of yours. You can’t use any legendary actions or lair actions of the new form. You assume the hit points and Hit Dice of the new form. When you revert to your normal form, you return to the number o f hit points you had before you transformed. If you revert as a result of dropping to 0 hit points, any excess damage carries over to your normal form. As long as the excess damage doesn’t reduce your normal form to 0 hit points, you aren’t knocked unconscious. You retain the benefit of any features from your class, race, or other source and can use them, provided that your new form is physically capable of doing so. You can’t use any special senses you have (for example, darkvision) unless your new form also has that sense. You can only speak if the creature can normally speak. When you transform, you choose whether your equipment falls to the ground, merges into the new form, or is worn by it. Worn equipment functions as normal. The DM determines whether it is practical for the new form to w ear a piece of equipment, based on the creature’s shape and size. Your equipment doesn’t change shape or size to match the new form, and any equipment that the new form can’t wear must either fall to the ground or merge into your new form. Equipment that merges has no effect in that state. During this spell’s duration, you can use your action to assume a different form following the same restrictions and rules for the original form, with one exception: if your new form has more hit points than your current one, your hit points remain at their current value.

Player's Handbook

Feather Fall

1-level Transmutation

Choose up to five falling creatures within range. A falling creature’s rate of descent slows to 60 feet per round until the spell ends. If the creature lands before the spell ends, it takes no falling damage and can land on its feet, and the spell ends for that creature.

PHB

Ice Knife

1-level Conjuration

You create a shard of ice and fling it at one creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 piercing damage. Hit or miss, the shard then explodes. The target and each creature within 5 feet of it must succeed on a Dexterity saving throw or take 2d6 cold damage
At higher levels: When you cast this spell using a spell slot of 2nd level or higher, the cold damage increases by 1d6 for each slot level above 1st.

Gust of Wind

2-level Evocation

A line of strong wind 60 feet long and 10 feet wide blasts from you in a direction you choose for the spell's duration. Each creature that starts its turn in the line must succeed on a Strength saving throw or be pushed 15 feet away from you in a direction following the line.   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, torches, 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 each of your turns before the spell ends, you can change the direction in which the line blasts from you.

Ice Storm

4-level Abjuration

A hail of rock-hard ice pounds to the ground in a 20-foot-radius, 40-foot-high cylinder centered on a point within range. Each creature in the cylinder must make a Dexterity saving throw. A creature takes 2d8 bludgeoning damage and 4d6 cold damage on a failed save, or half as much damage on a successful one.   Hailstones turn the storm's area of effect into difficult terrain until the end of your next turn.
At higher levels: When you cast this spell using a spell slot of 5th level or higher, the bludgeoning damage increases by 1d8 for each slot level above 4th.

PHB

Legend Lore

5-level Divination

Name or describe a person, place, or object. The spell brings to your mind a brief summary of the significant lore about the thing you named. The lore might consist of current tales, forgotten stories, or even secret lore that has never been widely known. If the thing you named isn’t of legendary importance, you gain no information. The more information you already have about the thing, the more precise and detailed the information you receive is.
The information you learn is accurate but might be couched in figurative language. For example, if you have a mysterious magic axe on hand, the spell might yield this information: “Woe to the evildoer w hose hand touches the axe, for even the haft slices the hand of the evil ones. Only a true Child of Stone, lover and beloved of Moradin, may awaken the true powers of the axe, and only with the sacred word Rudnogg on the lips.”

Xanathar's Guide to Everything

Investiture of Ice

6-level Transmutation

Until the spell ends, ice rimes your body, and you gain the following benefits:

• You are immune to cold damage and have resistance to fire damage.

• You can move across difficult terrain created by ice or snow without spending extra movement.

• The ground in a 10-foot radius around you is icy and is difficult terrain for creatures other than you. The radius moves with you.

• You can use your action to create a 15-foot cone of freezing wind extending from your outstretched hand in a direction you choose. Each creature in the cone must make a Constitution saving throw. A creature takes 4d6 cold damage on a failed save, or half as much damage on a successful one. A creature that fails its save against this effect has its speed halved until the start of your next turn.

PHB

Planar Ally

6-level Conjuration

You beseech an otherworldly entity for aid. The being must be known to you: a god, a primordial, a demon prince, or some other being of cosmic power. That entity sends a celestial, an elemental, or a fiend loyal to it to aid you, making the creature appear in an unoccupied space within range. If you know a specific creature’s name, you can speak that name w hen you cast this spell to request that creature, though you might get a different creature anyway (DM’s choice). When the creature appears, it is under no compulsion to behave in any particular way. You can ask the creature to perform a service in exchange for payment, but it isn’t obliged to do so. The requested task could range from simple (fly us across the chasm, or help us fight a battle) to complex (spy on our enemies, or protect us during our foray into the dungeon). You must be able to communicate with the creature to bargain for its services. Payment can take a variety of forms. A celestial might require a sizable donation of gold or magic items to an allied temple, while a fiend might demand a living sacrifice or a gift of treasure. Some creatures might exchange their service for a quest undertaken by you. As a rule of thumb, a task that can be measured in minutes requires a payment worth 100 gp per minute. A task measured in hours requires 1,000 gp per hour. And a task measured in days (up to 10 days) requires 10,000 gp per day. The DM can adjust these payments based on the circumstances under which you cast the spell. If the task is aligned with the creature’s ethos, the payment might be halved or even waived. Nonhazardous tasks typically require only half the suggested payment, while especially dangerous tasks might require a greater gift. Creatures rarely accept tasks that seem suicidal. After the creature completes the task, or when the agreed-upon duration of service expires, the creature returns to its home plane after reporting back to you, if appropriate to the task and if possible. If you are unable to agree on a price for the creature’s service, the creature immediately returns to its home plane. A creature enlisted to join your group counts as a member of it, receiving a full share of experience points awarded.

Plane Shift

7-level Conjuration

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. If you are trying to reach the City of Brass, for example, you might arrive in its Street of Steel, before its Gate of Ashes, or looking at the city from across the Sea of Fire, at the DM’s discretion. 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.   You can use this spell to banish an unwilling creature to another plane. Choose a creature within your reach and make a melee spell attack against it. On a hit, the creature must make a charisma saving throw. If the creature fails this save, it is transported to a random location on the plane of existence you specify. A creature so transported must find its own way back to your current plane of existence.

Conjure Celestial

7-level Conjuration

You summon a celestial of challenge rating 4 or lower, which appears in an unoccupied space that you can see within range. The celestial disappears when it drops to 0 hit points or when the spell ends. The celestial is friendly to you and your companions for the duration. Roll initiative for the celestial, which has its own turns. It obeys any verbal commands that you issue to it (no action required by you), as long as they don’t violate its alignment. If you don’t issue any commands to the celestial, it defends itself from hostile creatures but otherwise takes no actions.   The DM has the celestial’s statistics.
 
At higher levels: At Higher Levels. When you cast this spell using a 9th-level spell slot, you summon a celestial of challenge rating 5 or lower.
