Flame of Wrath (5e Equipment)
From D&D Wiki
Weapon (swords), rare (requires attunement)
A special sword that has the magical ability to catch on fire and to cast a flaming mount of the users imagination.
You can use your bonus action to ignite this sword, dealing additional 1d6 fire damage on a hit and shedding bright light in a 10-foot radius, plus dim light in another 10 feet. You can put out the flames as a bonus action.
In addition, while your sword is ignited, you can use your action to summon a flaming mount. The flaming mount has the same statistics as the nightmare, and appears on the ground, on a unoccupied space within 5 feet of you. You can also summon the creature on your space, automatically mounting and controlling the mount.
The flaming mount is friendly to you and your companions. It understands your languages and obeys your spoken commands. If you issue no commands, the creature defends itself but takes no other actions.
The nightmare remains by your side for 1 hour or until you put off the flames of the sword. Once you summon the flaming mount, you can't do it again until the next dawn. If the nightmare is killed, you can't summon it again for 7 days.
