Flame Blade is a spell in the Dungeons & Dragons role-playing game that allows a caster to create a sword made of fire. This magical weapon can be wielded in combat, dealing both slashing damage and additional fire damage to enemies. The spell lasts for a duration of up to 10 minutes, providing a versatile option for characters who prefer melee combat. To cast Flame Blade, a spellcaster must use a spell slot and have access to the Druid or Sorcerer class. The caster can summon the blade as a bonus action, making it a quick and effective choice during battles. The spell's unique combination of fire and slashing damage makes it particularly useful against foes vulnerable to fire.
