Thunderwave
You hold your hands out in front of you, and when you speak, your voice is amplified into a blast of sound which extends forward in front of you, blasting everything backwards.
Action - 15 ft. Cube** (5 ft.) - 1st Level (Evocation) - VS
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.
Constitution Save
Failure: Target takes 2d8 sonic damage* and is pushed 10 feet away from you.
Success: Target takes half as much damage and isn't pushed.
*Upcasting: Increase damage by 1d8 for each spell level above 1st.
**This spell is commonly misinterpreted to deal damage in an area around the caster. Instead, place the cube next to the caster, on one side.
