Shadow Blade is a spell in the game Dungeons & Dragons that allows a caster to create a blade of magical shadow. This weapon is considered a finesse weapon, meaning it can be used effectively with agility rather than brute strength. The blade deals psychic damage, making it unique compared to traditional weapons. When cast, Shadow Blade can be used in dim light or darkness, enhancing its effectiveness. The spell lasts for up to one minute, and the caster can choose to dismiss it at any time. It is particularly favored by characters like Rogues and Warlocks who thrive in stealthy situations.
