Booming Blade
cantrip, Evocation
- Casting time: 1 Action
- Range: Self (5-foot Radius)
- Components: S, M (a melee weapon worth at least 1 sp)
- Duration: 1 round
You brandish the weapon used in the spell’s casting and make a melee attack with it against one creature within 5 feet of you. On a hit, the target suffers the weapon attack’s normal effects and then becomes sheathed in booming energy until the start of your next turn. If the target willingly moves 5 feet or more before then, the target takes dice:1d8|noform|noparens|avg (1d8) thunder damage, and the spell ends.
This spell’s damage increases when you reach certain levels. At 5th level, the melee attack deals an extra dice:1d8|noform|noparens|avg (1d8) thunder damage to the target on a hit, and the damage the target takes for moving increases to dice:2d8|noform|noparens|avg (2d8). Both damage rolls increase by 1d8 at 11th level (dice:2d8|noform|noparens|avg (2d8) and dice:3d8|noform|noparens|avg (3d8)) and again at 17th level (dice:3d8|noform|noparens|avg (3d8) and dice:4d8|noform|noparens|avg (4d8)).
