Sword Burst

0-level (Cantrip) Conjuration

You create a momentary circle of spectral blades that sweep around you. Each creature within range, other than you, must succeed on a Dexterity saving throw or take 1d6 force damage.
At higher levels: This spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).

Booming Blade

0-level (Cantrip) Abjuration

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.
At higher levels: 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.

Comprehend Languages

1-level Divination (ritual)

For the duration, you understand the literal meaning of any spoken language that you hear. You also understand any written language that you see, but you must be touching the surface on which the words are written. It takes about 1 minute to read one page of text.   This spell doesn't decode secret messages in a text or a glyph, such as an arcane sigil, that isn't part of a written language.

Unearthed Arcana

Id Insinuation

1-level Enchantment

You unleash a torrent of conflicting desires in the mind of one creature you can see within range, impairing its ability to make decisions. The target must succeed on a Wisdom saving throw or be incapacitated. At the end of each of its turns, it takes 1d12 psychic damage, and it can then make another Wisdom saving throw. On a success, the spell ends on the target.
