Sword Coast Adventurer's Guide

Booming Blade

0-level (Cantrip) Evocation

As part of the action used to cast this spell, you must make a melee attack with a weapon against one creature within the spell's range, otherwise the spell fails. On a hit, the target suffers the attack's normal effects, and it becomes sheathed in booming energy until the start of your next turn. If the target willingly moves before then, it immediately takes 1d8 thunder damage, and the spell ends.

This spell's damage increases when you reach higher levels. At 5th level, the melee attack deals an extra 1d8 thunder damage to the target, and the damage the target takes for moving increases to 2d8. Both damage rolls increase by 1d8 at 11th level and 17th level.

Players Handbook

Eldritch Blast

0-level (Cantrip) Evocation

A beam of crackling energy streaks towards a creature within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 force damage.
At higher levels: The spell creates more than one beam when you reach higher levels: two beams at 5th level, three beams at 11th level, and our beams at 17th level. You can direct the beams at the same target or at different ones. Make a separate attack roll for each beam.

Hex

1-level Enchantment

You place a curse on a creature that you can see within range. Until the spell ends, you deal an extra 1d6 necrotic damage to the target whenever you hit it with an attack. Also, choose one ability when you cast the spell. The target has disadvantage on ability checks made with the chosen ability.   If the target drops to 0 hit points before this spell ends, you can use a bonus action on a subsequent turn of yours to curse a new creature.   A Remove Curse cast on the target ends this spell early.
At higher levels: When you cast this spell using a spell slot of 3rd or 4th level, you can maintain your concentration on the spell for up to 8 hours. When you use a spell slot of 5th level or higher, you can maintain your concentration on the spell for up to 24 hours.

Sleep

1-level Enchantment

This spell sends creatures into a magical slumber. Roll 5d8 , the total is how many hit points of creatures this spell can affect. Creatures within 20 feet of a point you choose within range are affected in ascending order of their current hit points (ignoring unconscious creatures).  
Starting with the creature that has the lowest current hit points, each creature affected by this spell falls unconscious until the spell ends, the sleeper takes damage, or someone uses an action to shake or slap the sleeper awake. Subtract each creature's hit points from the total before moving on to the creature with the next lowest hit points. A creature's hit points must be equal to or less than the remaining total for that creature to be affected.  
Undead and creatures immune to being charmed aren't affected by this spell.
At higher levels: When you cast this spell using a spell slot of 2nd level or higher, roll an additional 2d8 for each slot level above 1st.
2nd level: 7d8 hit points affected
3rd level: 9d8 hit points affected
4th level: 13d8 hit points affected
5th level: 15d8 hit points affected
6th level: 17d8 hit points affected
7th level: 19d8 hit points affected
8th level: 21d8 hit points affected
9th level: 23d8 hit points affected

PHB

Faerie Fire

1-level Evocation

Each object in a 20-foot cube within range is outlined in blue, green, or violet light (your choice). Any creature in the area when the spell is cast is also outlined in light if it fails a Dexterity saving throw. For the duration, objects and affected creatures shed dim light in a 10-foot radius.

  Any attack roll against an affected creature or object has advantage if the attacker can see it, and the affected creature or object can't benefit from being invisible.

Armor of Agathys

1-level Abjuration

A protective magical force surrounds you, manifesting as a spectral frost that covers you and your gear. You gain 5 temporary hit points for the duration. If a creature hits you with a melee attack while you have these hit points, the creature takes 5 cold damage.
At higher levels: When you cast this spell using a spell slot of 2nd level or higher, both the temporary hit points and the cold damage increase by 5 for each slot.
