RANGE/AREA: Self (15 ft)
COMPONENTS: V, S
DURATION: Instantaneous

DAMAGE/EFFECT: Thunder

• A wave of thunderous force sweeps out from you. Each creature in a 15-foot cube originating from you must make a Constitution saving throw. On a failed save, a creature takes 2d8 thunder damage and is pushed 10 feet away from you. On a successful save, the creature takes half as much damage and isn't pushed.
• In addition, unsecured objects that are completely within the area of effect are automatically pushed 10 feet away from you by the spell's effect, and the spell emits a thunderous boom audible out to 300 feet.

At Higher Levels: 

• When you cast this spell using a spell slot of 2nd level or higher, the damage increases by 1d8 for each slot level above 1st.

Components

• A spell's components are the physical requirements you must meet in order to cast it. Each spell's description indicates whether it requires verbal (V), or somatic (S). If you can't provide one or more of a spell's components, you are unable to cast the spell.

Verbal (V)

• Most spells require the chanting of mystic words. The words themselves aren't the source of the spell's power; rather, the particular combination of sounds, with specific pitch and resonance, sets the threads of magic in motion. Thus, a character who is gagged or in an area of silence, such as one created by the silence spell, can't cast a spell with a verbal component.

Somatic (S)

• Spellcasting gestures might include a forceful gesticulation or an intricate set of gestures. If a spell requires a somatic component, the caster must have free use of at least one hand to perform these gestures.
