Blazing Smite (5e Spell)
From D&D Wiki
|Casting time:||1 bonus action|
|Duration:||Concentration, up to 1 minute|
The next time you hit a creature with a melee weapon attack during this spell's duration, your weapon roars with divine flame, and the attack deals an extra 2d8 fire damage and 2d8 radiant damage to the target. Furthermore, 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 1d8 fire damage and 1d8 radiant damage at the start of each of its turns.
