Bounding Flame (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Duration:||Concentration, up to 1 minute|
You create a magical flame which appears in your space, and harms other creatures but not you. The flame effectively fills a 5-foot cube, and persists for the duration. It sheds bright light in a 20-foot radius, and dim light for an additional 20 feet. When you cast this spell, you can move this flame up to 10 feet in any direction along the ground. You can move it again on subsequent turns by using a bonus action. Whenever the flame moves into creature's space, that creature must make a Dexterity saving throw. If a creature moves through or into the flame's space on its own turn, it must make a Dexterity saving throw. On a failed save, the creature takes 1d8 fire damage.
This spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
