Fire Volley (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Duration:||Concentration, up to 1 minute|
You shoot a bolt of fire at a creature or object that you can see within range. Make a ranged spell attack against the target. If the attack hits, the creature takes 8d8 fire damage. If the target is a creature or a flammable object, it ignites. Until a creature takes an action to douse the fire, the target takes 2d8 fire damage at the start of each of its turns.
As an action on each of your turns until the spell ends, you can hurl another bolt of fire.
